         COPYRIGHT (C) 1994 BY MERRILL CONSULTANTS DALLAS TEXAS         
                                                                        
0. IBMs MVS Version 5 Workload Manager and Parallel Sysplex Processors  
                                                                        
  IBM presentations at the recent SHARE meeting provided early insight  
  into the expected announcement of new mainframe hardware using CMOS   
  technology, and a new MVS/ESA 5.1 with its Workload Manager component 
  that will revolutionize the measurement and management of MVS.        
                                                                        
  For the first time in any computer system, the operating system will  
  operate in concert with its subsystems to not only measure the service
  objectives, but also to react when those service goals are not being  
  met, and MVS will assign resources (for example, dispatching priority)
  so that the service goal is met!                                      
                                                                        
  Previously, only resource consumption was measured, and delivery of   
  resources was managed by MVS without regard to response times or      
  workloads, but now, workloads are defined (eg., CICS transactions     
  starting with PAY*) and their service goals are measured (eg., 90%    
  completed in 1 second) so that your business plan controls the        
  delivery of computer resources.                                       
                                                                        
  This feedback loop from the application to the operating system in    
  terms of business purpose is truly unique, and there is even more     
  power to come in this new world, because the Workload Manager's       
  measurements and decisions apply not just to a single MVS image, but  
  across the sysplex, so that multiple CPUs in multiple boxes can       
  operate in concert!                                                   
                                                                        
  And the new Parallel Sysplex mainframes are multiple  CPUs in         
  multiple boxes!  These new CMOS technology parallel processors        
  will be driven by the new MVS component.  Previous MVS hardware used  
  BiPolar technology which was fast, but was also expensive, and it     
  generated lots of heat that had to be cooled, often with water.  The  
  CMOS technology of PCs and workstations has been harnessed into small,
  inexpensive, air cooled CPUs that, while individually a little slower,
  can deliver the same total power as the BiPolar technology because    
  they operate in parallel, to dramatically reduce the cost of mainframe
  computing, while providing all of the industrial strength, security,  
  management, economy of scale, backup, and control that will always be 
  missing in networks of independent workstations and PCs.              
                                                                        
  While some of what MVS used to do really does belong on workstations  
  or PCs, many workloads were moved off the mainframe only because of   
  the disparity between BiPolar and CMOS costs;  the CMOS platforms and 
  the workload measurement and management aspects of the new MVS will   
  stem the tide of irrational downsizing, and decisions of what platform
  will service what workload will be based on location of data and the  
  appropriateness of the technology instead of short term false economy!
                                                                        
  A VP of DP at an oil company was required to supply workstations to   
  his petroleum engineers because of only hardware cost savings, but he 
  now laments that his engineers spend half of their time looking for   
  oil, and the other half of their time looking for disk space on their 
  workstations!  Each engineer's productivity was diluted as each became
  half-time engineers and half-time data center managers.               
                                                                        
  That is unlikely to occur again with CMOS mainframes and MVS 5.1!     
                                                                        
  I am tremendously impressed by IBM's forward thinking design of this  
  new world of mainframes in which company business goals direct the use
  of computer technology, and not vice versa.                           
                                                                        
I. MXG Software Production Version 11.11, dated March 26, 1994, was     
   shipped with MXG Newsletter TWENTY-FIVE.                             
                                                                        
  Critical notes about MXG Version 11.11:                               
                                                                        
  - Products that require MXG 11.11 because of incompatible records:    
                                                                        
    DB2 Version 3.1.0.

    Sterling's NDM, now Connect Direct 1.7.01.                          
                                                                        
  - ANALDB2R users must use MXG 11.11 because of report corrections.    
                                                                        
  - You MUST use member CONFIG from this MXG SOURCLIB or you will get   
    many strange errors! (If you are still stuck at SAS 6.06, see Change
    11.187 and use CONFIG06).  Member CONFIG executes %VMXGINIT with    
    INITSTMT='%INCLUDE SOURCLIB(VMXGINIT); %VMXGINIT;' to initialize the
    internal macro variables introduced in Change 11.150.               
                                                                        
  - If any of these members exist in your USERID.SOURCLIB(s) libraries: 
               ASUMDBDS ASUMDB2A ASUMDOS  ASUMHPCS ASUM70PR             
               DAILYDSN GRAFDB2  GRAFLPAR TRNDDB2A                      
    or if you use %VMXGSUM in your own report/summarization programs,   
    then you MUST read the incompatibility details in Section VIII and  
    in Change 11.309 and you will need to re-tailor your changes.       
                                                                        
  - MXG 11.11 requires SAS 6.08 at maintenance TS407 plus Zap Z6088203  
    to correct all known SAS errors.  See Section VIII.                 
      (Note: the online NEWSLETTER was revised - the original text also 
             listed Z6086442 as required, but later input from SAS      
             Institute Tech Support indicated that 6442 was already     
             included in Maintenance TS407).

  TYPEZRB - RMF III VSAM file for MVS/ESA 4.2 and 4.3 is not correct.   
                                                                        
  Huron   - Huron SMF record is not supported yet; no sample data SMF   
            data was provided, and the printed DSECTs were massive and  
            needed in machine readable form.  Planned for 2nd quarter.  
                                                                        
  EPIC    - LEGENT has not provided the format of their tape catalog;   
            instead, they want you to use the output of their extract   
            program, which means double processing and kludgy coding.   
            Nothing planned until LEGENT supplies needed formats.       
                                                                        
II.   MXG Technical Notes                                               
                                                                        
 1.  Executing MXG on PCs and Workstations                              
                                                                        
 a. Non-portability of SAS data libraries with $HEX variables.          
                                                                        
SAS data libraries are currently not completely portable between EBCDIC 
and ASCII platforms, because SAS Transport Procedures (UPLOAD, DOWNLOAD,
etc.) convert all character values from EBCDIC to ASCII.  Thus character
variables that contain binary data (i.e., those with $HEX format) are   
corrupted when moved between platforms.  An MVS '40'X value is changed  
to a '20'X under ASCII versions, causing bit tests to fail and wrong    
values to be printed.                                                   
                                                                        
SAS Institute recognizes the unilateral conversion as a design problem, 
and had considered changing the Transport Procedures so they would NOT  
translate any variable with the special INFORMAT name of $NOTRAN.  Code 
was added to MXG to assign the $NOTRAN informat to all MXG character    
variables that contain binary data, in anticipation of the SAS design,  
and member FORMATS creates a $NOTRAN informat.  However, SAS Institute  
has now decided that the informat attribute is inappropriate for this   
usage, and is investigating alternative solutions for SAS Version 7.    
  Note: Aug 2, 2004:  See Change 22.192. All INFORMAT xxx $NOTRAN. ;    
  statements were removed from MXG source code.                         
                                                                        
Until SAS Institute resolves this design issue, you must be aware of any
character variables that contain binary ($HEX) data, and convert their  
values back to the original value after downloading the SAS Data Sets   
on the ASCII platforms, using the new MXG utility UTILCVRT.             
                                                                        
 b. Datasets SORTed BY character variables are unsorted after download. 
                                                                        
Datasets that were sorted BY character variables under EBCDIC will not  
be sorted under ASCII (and vice-versa), because the EBCDIC collating    
sequence is different than ASCII.  You will have to re-SORT the data.   
                                                                        
 c. SAS Source code changes made so that MXG executes under ASCII SAS:  
                                                                        
 - All numeric informats whose interpretation depends on the execution  
   platform were replaced with a macro variable whose value is now set  
   in VMXGINIT (which is now automatically invoked by the INITSTMT= in  
   the CONFIG member).  The numeric informats macro variable names and  
   their values under EBCDIC and ASCII platforms are:                   
                                                                        
     Macro variable       EBCDIC value       ASCII value                
        &PIB                 PIB              S370FPIB                  
        &IB                  IB               S370FIB                   
        &PD                  PD               S370FPD                   
        &PK                  PK               PK                        
        &RB                  RB               S370FRB                   
        &NUM                 null             S370FF                    
                                                                        
 - All character variables that contain printable data were changed to  
   be INPUT with $EBCDICn. informat instead of $CHARn.                  
                                                                        
 - All character variables that contain hexadecimal data (i.e., have    
   format $HEX) were changed to be input with $CHAR informat, and all   
   were also explicitly assigned the informat named $NOTRAN.            
                                                                        
 - All date variables input as DDMMYY, MMDDYY, or YYMMDD and all time   
   variables input as TIME or HHMMSS were replaced with individual      
   inputs of DD MO and YY or HH MM and SS using the &NUM macro variable 
   and then dates are created with the MDY function.  All dates are now 
   formatted DATE7 (to avoid confusion between USA and European date    
   formats).                                                            
                                                                        
 - Character variables whose length had been set in a FORMAT statement  
   were instead declared in a LENGTH statement for consistency.         
                                                                        
 - Use of INPUT(string,format) were examined, and if the format item    
   expected EBCDIC representation, the input of the string was $CHAR,   
   but if the format item expected printable character/numeric date, the
   string was input with $EBCDIC.                                       
                                                                        
 - Formats that test for hexadecimal data values were identified (in    
   member FORMATS) and variables using those formats were changed to be 
   INPUT $CHAR with INFORMAT $NOTRAN.                                   
                                                                        
 - Numeric variables minimum LENGTH is 3 under ASCII SASs.  Previously, 
   length 2 could be used.                                              
                                                                        
 - Obscure input informats $PHEX and $CHARZB have no exact equivalent   
   for processing MVS data under ASCII platforms.  Each case has to be  
   modified with unique coding.                                         
                                                                        
 - The algorithm used to identify EBCDIC numerics from alphabetics:     
      IF var LT '0' ==> alphabetic      IF var GE ='0' ==> numeric      
   is invalid under ASCII.  EBCDIC numbers are 'F0'x->'F9'x, which is   
   greater than EBCDIC alphabetics ('81'x->'E9'x), but ASCII numbers are
   '30'x->'39'x, which is smaller than ASCII alphabetics ('41'x->'7A'x).
   Only VMACVMXA's building of the INSTREAM format used this algorithm. 
                                                                        
 - Use of $VARYINGnnn must be examined individually.  $VARYINGnnn acts  
   like $CHAR instead of $EBCDIC, so strings input with $VARYING that   
   are printable characters must be converted with:                     
         INPUT variable $VARYINGnn. lenvar @;                           
         variable=INPUT(variable,$EBCDIC.);                             
         variable=TRANSLATE(variable,' ','80'x);                        
     Note: the TRANSLATE was required because the INPUT function was    
           used.  SAS Institute pointed out that the INPUTC(str,val,len)
           function would have eliminated the need for TRANSLATE().     
   For character variables that do not contain printable characters, the
   INPUT and TRANSLATE are not required, but the variable must be FORMAT
   with $HEX, and INFORMAT with $NOTRAN.                                
                                                                        
 - Statistics about Change 11.150:  The 244 members starting with 'V'   
   were PROC SOURCEd into a single text file of 128,144 lines (10MB).   
   Three TSO sessions totalling 40 hours across three days issued 11,810

    This was a fairly intense TSO EDIT session for 40 session hours!    
                                                                        
                                                                        
  As a result of these changes, MXG 11.11 Software can now be executed  
  on ASCII platforms (i.e., on PCs with WINDOWS or OS/2, or on          
  workstations with UNIX) to read raw data records (i.e., SMF,          
  VM/Monitor, etc.) that were downloaded, and MXG will create the same  
  MXG datasets that you have been using all along on your EBCDIC        
  platforms (i.e., MVS or VM)!                                          
                                                                        
 d. Downloading the MXG Source Library from MVS to ASCII PC Platforms.  
                                                                        
   This example shows how you can use IND$FILE to convert the MVS PDS   
   into one ASCII file per member.                                      
                                                                        
   The MXG members must be unnumbered to execute correctly under the SAS
   ASCII versions, and each ASCII file must be named "member.SAS".      
                                                                        
   First, create MXG.IEBUPDTE.NUMBERED, an 80-byte numbered sequential  
   file in IEBUPDTE format from your MXG.SOURCLIB PDS. (Since this is   
   an exact copy of the MXG IEBUPDTE distribution tape, so you could    
   alternatively just copy the tape into MXG.IEBUPDTE.NUMBERED.)        
   Sample JCL for these steps is in member JCLDOWNL.                    
                                                                        
      //IEBUPDTE EXEC SAS608                                            
      //IN     DD DSN=MXG.MXG.SOURCLIB,DISP=SHR                         
      //OUT    DD DSN=MXG.IEBUPDTE.NUMBERED,                            
      //          DISP=(NEW,CATLG),SPACE=(CYL,(69,5)),UNIT=DASD,        
      //          DCB=(RECFM=FB,LRECL=80,BLKSIZE=32720),VOL=SER=MXGNNN  
          PROC SOURCE INDD=IN OUTDD=OUT;                                
                                                                        
   Second, create MXG.IEBUPDTE.UNUMBERD, a 72-byte unnumbered copy of   
   the IEBUPDTE-format sequential dataset, by truncation:               
                                                                        
      //TRUNCATE EXEC SAS608                                            
      //IN       DD DSN=MXG.IEBUPDTE.NUMBERED,DISP=SHR                  
      //OUT      DD DSN=MXG.IEBUPDTE.UNUMBERD,                          
      //            DISP=(NEW,CATLG),SPACE=(CYL,(65,6)),UNIT=DASD,      
      //            DCB=(RECFM=FB,LRECL=72,BLKSIZE=23400),VOL=SER=MXGNNN
          DATA _NULL_; INFILE IN; FILE OUT;                             
           INPUT @1 CARD $CHAR72.; PUT @1 CARD $CHAR72.;                
                                                                        
   (Or you could use SPF 3.3 (COPY) to copy with truncation.)           
                                                                        
   Since ASCII versions of SAS require unnumbered source code, we want  
   to truncate on the mainframe before we download, as that will reduce 
   the download time.  Furthermore, unnumbered files require less space 
   on the PC than the same file if numbered, because ASCII source files 
   are stored as a variable-length, delimited string, with trailing     
   blanks removed.  Note that the DIR command shows the size of the PC  
   Source directory as only 25MB, but actually 39MB of disk space is    
   needed for that directory, because of space waste at the end of each 
   of the 2500+ individual files in that directory!

        PK Zip of PC Source Directory      5,766,824   5MB              
                                                                        
        Note that the zipped MXG Source Library now fits on only four   
        "stiffie" disks - the Australian nickname for 3-1/2 floppies.   
                                                                        
   Third, on the PC, create directories:                                
                                                                        
     MD \MXG\SOURCLIB       MD \MXG\PDB                                 
     MD \MXG\USERID         MD \MXG\CICSTRAN                            
     MD \MXG\SMFDATA        MD \MXG\SPIN                                
     MD \MXG\FORMATS        MD \MXG\DB2ACCT                             
                                                                        
   Fourth, use IND$FILE to download mainframe's MXG.IEBUPDTE.UNUMBERD   
   into the PC's \MXG\SOURCLIB\IEBUPDTE.UNU, specifying ASCII and CRLF  
   options for the download.  Depending on line speed, this can take    
   from seventeen minutes to seven hours.  The mainframe file is about  
   44MB; coax moves at 1 MB/min, a 4 MBit LAN moves at 2.25 MB/min,     
   while 19.2KB dial-up can only move about 5-6MB/hour!                 
                                                                        
   Fifth, download member IEBUPDTE of the MXG SOURCLIB PDS using        
   IND$FILE into \MXG\SOURCLIB\IEBUPDTE.BAS, using ASCII CRLF.          
                                                                        
   Sixth, use BASIC to execute IEBUPDTE.BAS to read IEBUPDTE.UNU, which 
   splits that sequential file and creates a separate PC file for each  
   member of the original PDS.  For example:                            
                                                                        
          CD \MXG\SOURCLIB                                              
          BASICA IEBUPDTE.BAS                                           
          and reply with filename  IEBUPDTE.UNU                         
                                                                        
   IEBUPDTE.BAS creates each file with the name of "member.SAS", so that
   the %INCLUDE statements in MXG, of the form:                         
        %INCLUDE SOURCLIB(XXXXXXXX);                                    
   are recognized by the ASCII SAS version.                             
                                                                        
   The Basic program to split the sequential file into individual PC    
   files took about 48 minutes on a 486/33..                            
                                                                        
 e. Downloading raw SMF, VM/Monitor, etc. data from MVS with IND$FILE,  
    or with ftp.                                                        
                                                                        
   You can use IBM's IND$FILE under TSO to an SDLC link (Barr Systems   
   BARRSNA or Extra's ATTACHMATE), or to an ASYNC link (IBM's INPCS),   
   or you can use ftp (binary) to download V, VB, or VBS files.         
                                                                        
   First, the data file to be downloaded must have DCB attributes of    
   RECFM=U and BLKSIZE=32760.  You can make a copy of the original SMF  
   data with the changed DCB using this JCL:                            
                                                                        
        //  EXEC PGM=IEBGENER                                           
        //SYSPRINT DD SYSOUT=*                                          
        //SYSIN    DD DUMMY                                             
        //SYSUT1   DD DSN=MXG.SMFDATA.ORIGINAL,DISP=SHR,                
        //            DCB=(RECFM=U,BLKSIZE=32760)                       
        //SYSUT2   DD DSN=MXG.SMFDATA.RECFMU,DISP=(NEW,CATLG),          
        //            UNIT=DASD,VOL=SER=MXGNNN,SPACE=(CYL,(60,5)),      
        //            DCB=(RECFM=U,BLKSIZE=32760)                       
                                                                        
   and then download MXG.SMFDATA.RECFMU.  If you cannot afford the DASD 
   space, and if no other job will try to access the original SMF file  
   for the duration of the download, you could simply change its DCB    
   attributes, using this JCL:                                          
                                                                        
        //  EXEC PGM=IEBGENER                                           
        //SYSPRINT DD SYSOUT=*                                          
        //SYSIN    DD DUMMY                                             
        //SYSUT1   DD DSN=MXG.SMFDATA.ORIGINAL,DISP=SHR                 
        //SYSUT2   DD DSN=MXG.SMFDATA.ORIGINAL,DISP=MOD,                
        //            DCB=(RECFM=U,BLKSIZE=32760)                       
                                                                        
   and then download the changed ORIGINAL file (and then reset the DCB).
   We have to either make a copy or change the DCB attributes because we
   cannot override the DCB attributes used by IND$FILE.  If you instead 
   use SAS/CONNECT, or any other file transfer protocol that allows you 
   to preallocate or respecify the DCB attributes of the file to be     
   downloaded, the extra step can be avoided.  The important aspect is  
   that the downloader must see its input as RECFM=U,BLKSIZE=32760.     
                                                                        
   Second, now that you have copied or reset your SMF raw data in a     
   dataset with DCB=(RECFM=U,BLKSIZE=32760), you can then use IND$FILE  
   to download the SMF data set into \MXG\SMFDATA\SMFDATA.U on your PC. 
   You must have the NOCRLF and NOASCII options in effect (i.e., do not 
   specify CRLF nor ASCII) so that NO carriage return/line feed         
   ('13'x,'26'x) is inserted in the data, and so that NO conversion from
   EBCDIC to ASCII is done. We want the PC file to be a serial stream of
   unmodified blocks of mainframe data, including BDWs and RDWs.        
                                                                        
   You cannot point to a VBS file on the mainframe and bring it down to 
   the PC; you MUST have the downloading program see RECFM=U, so that   
   the raw SMF data is brought down as a complete block, including both 
   the BDW and the RDW.  Nothing else will work!                        
                                                                        
   If you are direct connected, you can expect a 200MB file to take from
   40 minutes (5MB/min) to 100 minutes (2MB/min), depending on speed and
   contention.  Using dial-in at 19.2KB, it will take 33 hours (6MB/hr) 
   to download the 200 MB SMF file!                                     
                                                                        
   This download time for SMF data may be reducible with PKZIP/MVS.  On 
   the PC, PKZIP reduced the 200MB SMF file to only 30MB, an actual     
   compression factor of nearly 8:1, taking only 65 elapsed minutes to  
   compress on the Model 95, so downloading and rebuilding a ZIPed file 
   at 19.2KB might take only 6 hours after compression.  PKZIP/MVS uses 
   the same algorithms and should be suitable for reduction of download 
   time of large SMF files, as well as the MXG Source.  Benchmarks are  
   planned.  (PKZIP/MVS is available from Scott Avera at ASI, Dayton,   
   OH, 513-222-9012).                                                   
                                                                        
 f. Moving the raw data and source libraries from PC to UNIX with ftp.  
                                                                        
   You can also use ftp if you have a TCP/IP connection.  This example  
   shows the ftp commands to copy the MXG SMF and Source data from a    
   PC to UNIX; a similar sequence could be used to download directly    
   from MVS with TCP/IP.                                                
                                                                        
   - FTP to the machine that has the data and log on:

   - Change directories to where the data is:                           
                                                                        
        cd SMFDATA

   - Make sure download is binary

   - Change directory to source library and mode to ASCII:              
                                                                        
        cd SOURCLIB

 g. Environmental options (CONFIG.SYS,AUTOEXEC.SAS,etc) required.       
                                                                        
  SAS For Windows 6.08 at TS405 or later maintenance is required.       
                                                                        
  Remove any Disk Caching Software, notably Microsoft's SMARTDRV:       
                                                                        
     No problems were encountered whatsoever with an 85MB SMF file and  
     its BUILDPDB, but when the 200MB file was executed, using a 1700MB 
     SCSI disk volume for input, work, swap, and PDB output, that 1700MB
     disk was completely destroyed by SMARTDRV.  ("INVALID MEDIA TYPE"  
     and total corruption of data).  I believe the error is encountered 
     when the total file size being written exceeds 524MB, the limit for
     an IDE partition; it appears that hardware limit is somehow        
     embedded in SMARTDRV in DOS 5.0.                                   
                                                                        
     Removal of SMARTDRV eliminated the overwrite of the SCSI disk, but 
     the run time was now increased by 50%!  Disk caching is still under
     investigation!                                                     
                                                                        
  CONFIG.SYS requires this additional specification:                    
                                                                        
          FILES=255                                                     
                                                                        
     The FILES parameter is needed to prevent an "OUT OF FILE HANDLES"  
     condition.                                                         
                                                                        
  AUTOEXEC.BAT requires this additional specification:                  
                                                                        
          SHARE /L:200 /F:10264                                         
                                                                        
     The SHARE parameters are required if you use SHARE (required with  
     some LANs and by SPFPC) to prevent "OPERATING SYSTEM ERROR 36."    
     The /F parameter defines how many bytes are available to store     
     file names.  Since the full path and file name is stored, if you   
     use more sub-directories and/or longer directory names, you may    
     still have to increase the /F: value.                              
                                                                        
                                                                        
   AUTOEXEC.SAS changes required:                                       
                                                                        
      Member AUTOEXEC.SAS was downloaded into your \MXG\SOURCLIB        
      directory.  It needs to be copied into your \SAS directory, as it 
      sets up both the required file names, and invokes the %VMXGINIT   
      member that defines the &PIB and other macros described earlier.

  Yes, you CAN execute MXG under SAS on ASCII platforms;                
   on PCs with much longer run times, on Workstations quite comparably. 
  But just because you CAN does not mean you SHOULD!                    
                                                                        
  Does a corporate resource (the PDB) belong on a single-user platform? 
  Backup and Archiving of PDB directories will require manual management
   of tapes, a process which is automated on MVS.                       
  Large volume transfer will impact other LAN users during prime time.  
                                                                        
  Nevertheless, the economic motivation for downsizing may be strong,   
   if MXG is the only SAS user on MVS; the HP 720 costs $25,000, the    
   PS/2 is a $5,000 box, and SAS is much cheaper on ASCII than EBCDIC!  
                                                                        
 2. MXG Release 11.11 requires SAS Version 6, but it is still possible  
    to run MXG 11.11 under SAS 5.18, with these considerations:         
                                                                        
 a. You need member SASOPTV5 from MXG 11.11, and the first statement of 
    your program must be: be %INCLUDE SOURCLIB(SASOPTV5);               
    (This now invokes %VMXGINIT and defines the &PIB++ macros.)         
 b. You must change all occurrences of $EBCDIC to $CHAR in the entire   
    MXG sourclib.  (Version 5 does not recognize $EBCDIC.)              
 c. You must change all occurrences of double-exclamation-points "!!",  
    ('5A'x) with double-solid-vertical-bars "  " ('4F'X).               
 d. If there are any other problems, let me know.  None of my test sites
    still have SAS 5.18, and truly, everyone should be on Version 6 now!
                                                                        
 3. Running the MONTHBLD program on a day other than the 1st day of the 
    month requires these modifications in member MONTHBLD:              
 a. If the rerun day is within the same week as the first day of the    
    month, it is only necessary to change MONTHBLD and rerun:           
     In the DATA _NULL_ step, replace  TODAY=TODAY(); with the specific 
     date of the first day of the month:  TODAY='01APR94'D;             
     This will calculate _BEGIN and _END dates correctly and will avoid 
     the USER ABEND 1111 condition.                                     
 b. If the rerun day is in the week after the week of the first day of  
    the month, you will need to change both the TODAY= and the DAY=     
    statements in the DATA _NULL_ step to read:                         
      TODAY='01DEC93'D;                                                 
      DAY='MON';                                                        
    as that will cause none of the Daily PDBs to be read; instead, the  
    five previous weekly datasets will be read and selected from to then
    create the monthly dataset.  You will need to point the five DD's in
    your JCL for //WEEK1 - //WEEK5 to the five specific weekly PDBs that
    span the month that you are recreating.                             
 c. Note added August, 1996.                                            
    If you have to recreate a month PDB well after the fact:  Assume you
    are missing one weekly PDB from FEB.  Yesterday you created the week
    PDB, but its observations have ZDATE=13AUG96 (for example).  You can
    modify the SET statement in the heart of MONTHBLD, below) as shown  
                                                                        
     - remove the _D1._DSET  thru _D2._DSET text from the SET statement 
       (so the Daily PDBs won't be read)                                
                                                                        
     - change the test for _BEGIN and _END to the explicit dates to be  
       selected from the five WEEKly PDB's being read, remembering that 
       the ZDATE selection is from the 2nd of the Month to the 1st of   
       the next (because on the 2nd of this Month is when you process   
       the work of the 1st, etc.).

III.  MVS Technical Notes                                               
                                                                        
 1. Impact of VSAM CI Size on DASD Space and SMF Write Activity         
                                                                        
    I have recommended setting the CISIZE of SMF VSAM data sets to      
    half-track value (26K for 3390), because that should minimize the   
    number of physical blocks read or written, and reducing the number  
    of blocks always reduces both the CPU and the elapsed time to read  
    or write SMF data to/from the VSAM file.  Or so I thought!          
                                                                        
    One site increased its CISIZE from 8K to 26K and found that they had
    to double the size of their SMF VSAM data set from 500 to 1000 cyl, 
    but the size of the 450 cylinder SMF dump output data set did not   
    change!  Lawrence Jermyn and Tim VanderHoek at Fidelity opened a    
    problem with IBM.  Kathy McEwen at SMF Support replied in her ETR   
    3E902, which provided me with insight into the internal architecture
    of the SMF writer; that ETR precipitated this analysis.             
                                                                        
    Because the SMF writer does not write true VBS records, lots of VSAM
    space can be wasted; the amount wasted depends on both the CI Size  
    and the number of logical records that are greater than the CI Size.
    This is not really new; SMF has always worked this way since the    
    1978 rewrite that introduced VSAM files, but the combination of the 
    now-possible larger CI size of 26624 on 3990s, combined with lots of
    CICS/ESA type 110 records (which are typically close to 32760 bytes 
    long) can dramatically increase the wasted DASD space.              
                                                                        
                                                                        
    The SMF writer uses a "pseudo-VBS" algorithm to write records to the
    VSAM data set.  New variable-length records are put into the current
    CI as long as the new record fits.  If there is not enough room for 
    the new record in the current CI, the new record is normally NOT    
    spanned; instead, the new record is written into the start of the   
    next CI.  Record spanning only occurs when the new record's LRECL is
    greater than the CI size of the VSAM data set.  In that case, the   
    new record starts in the next CI and fills as many CIs as are needed
    to span the long record, but then any space remaining in the final  
    CI for the long record is never used.  Consider this example with   
    records of 1000, 32760, 1000, and 32760 bytes using a 26624 CI size:
                                                                        
            ------track 1------ ------track 2------ ------track 3------ 
             CI=1      CI=2      CI=3      CI=4      CI=5      CI=6

    Thus 67,520 data bytes were written, but the 6 CIs (159,744 bytes)  
    required THREE full 3390 tracks for the four SMF records.           
                                                                        
    If a CI size of 8192 is used, these 4 SMF records are written in 10 
    10 CIs (81,920 bytes) on less than TWO tracks, using less space:

    Why does SMF not span all records?  It all goes back to the original
    SMF BSAM architecture introduced in OS/360 in 1969.  The SMF dump   
    program would fail with an ABEND 002 when it encountered broken VBS 
    records.  If records were always spanned, a system crash would cause
    the SMF dump program to ABEND 002, because the last block written to
    DASD before the crash would have indicated spanning, but the next   
    block found would be the new IPL record that was written after the  
    crash!  So as to minimize the probability of the 002 abend, the     
    original SMF writer only spanned when the LRECL was greater than the
    BLOCKSIZE.  Since records written by BSAM were still truly variable 
    records, whether spanned or not, there was no wasted space.  This   
    pseudo-VBS algorithm was repeated in the 1978 VSAM- based redesign, 
    but that implementation fixed the CI size at 4096, so wastage was   
    small.  Now, with many long SMF records and the now-possible larger 
    CI sizes, the pseudo-VBS algorithm of the SMF writer not only wastes
    DASD space, it also causes the SMF Writer to issue many more VSAM   
    physical writes than would be if ALL records were spanned.          
                                                                        
    So what is the right CI size? It depends mostly on how many records 
    are greater than the CI size, and also on the order in which records
    are written.  It also depends on whether you want to minimize the   
    DASD space required, or whether you want to minimize the number of  
    write operations performed by the SMF writer (i.e., the overhead of 
    the SMF writer).  Only by reading your SMF file to simulate the VSAM
    write activity of the SMF Writer with different CI Sizes, can you   
    determine the CI size impact on your installation.  MXG's ANALSMF   
    program now contains "The SMF Simulator" which reads your input SMF 
                                                                        
    file and analyzes the impact of various CI sizes at your site.

    Here, the 26K CI Size minimizes VSAM space, but the 26K savings is  
    only 6% less than 4K, so the CI Size impact on DASD is small.       
    However, the 26K CI Size reduces the number of SMF Write operations 
    to one-sixth the number at 4K; clearly the large CI Size here       
    benefits both DASD Space and SMF Writer operations.

    Here, the 4K CI Size minimizes DASD space, using 6745 fewer cyls    
    (26% less) than the 26K CI size, but that 4K CI Size maximizes the  
    CI writes (over 4 times as many writes than the 26K CI size), so the
    minimization of both DASD space and CIs written here is mutually    
    exclusive!  The best compromise here is the 16K CI size, as 16K uses
    only 3% more DASD space than the minimum DASD, and 16K writes only  
    15% more CIs than the minimum write activity.                       
                                                                        
    The IBM ETR recommended a CI Size of 8K (based upon the average SMF 
    record length of 28000 reported by the SMF Dump program); while 8K  
    does require slightly less DASD space, the Simulator provides better
    basis for optimizing both DASD Space and Writes than average size!  
                                                                        
    The SMF development team has been made aware of these results, and  
    is investigating the feasibility of spanning all records so as to   
    minimize both the size of the VSAM file and the number of writes.

  Note: As there are 86,400 Seconds in one day, SMF on SYS2 only wrote  
  during 1 out of every 8 seconds.  Even on the massive systems, writes 
  occur seconds apart (and devices can handle tens of I/Os per second!) 
                                                                        
 The peak SMF writer activity always occurs during the second when the  
 RMF interval expires.  For the 500MB case 1 site, the ten peak seconds 
 of the day show how little activity actually occurs; furthermore, no   
 task is waiting while SMF writes asynchronously from its buffers:

 2. An increase in recorded CPU TCB time and total CPU Busy time has    
    been found when sites have installed Microcode Level SEC 228150 plus
    MVS/ESA 4.2, and are running in an LPAR Environment.  Sites that had
    measured CPU TCB time variability in the range of 0-7% before the   
    changes, found the variability range was now from 0-15%.  When these
    sites upgraded to MVS/ESA 4.3, the CPU variability returned to the  
    earlier, lower, values.  This turns out to be yet another LUE, or   
    Low Utilization Effect, even though the PR/SM hardware was running  
    at 100% CPU busy!                                                   
    What happens, according to IBM's Gary Hall, at the SHARE 1994 Winter
    Meeting, is that while "SEC150" is best known for giving us EMIF, it
    also revamped the microcode for the LPAR Dispatcher, aiming to      
    minimize the LUE, of PR/SM.  However, that microcode level, plus    
    changes in the MVS dispatcher (to make it more event driven, so as  
    to reduce SIGPs, for example) conspired together, and ole MVS/ESA   
    4.2 hammered the LPAR environment, causing the recorded CPU time to 
    increase!                                                           
       Consider a PR/SM machine with several production LPARs, and with 
       a nearly-idle 3090-600 LPAR for SYSPROGs:  even though the rest  
       of the LPARs are driving the real engines to 100% busy, and even 
       though nary a SYSPROG is logged on to this LPAR (so this LPAR's  
       utilization is very low), ole 4.2 in this LPAR frequently wakes  
       up each of the 6 CPUs it thinks it's got, to see if there is any 
       work for 4.2 to do!  That means each of the 6 Logical CPUs have  
       to be dispatched on a real CPU, so LPAR management now has to    
       steal a real engine from your online system, and that engine then
       has to invalidate lines in its HSB, the High Speed Buffer (also  
       called the CPU cache), to make room for the SYSPROG LPAR's MVS   
       instructions, so that that MVS can execute instructions, to find 
       out that there is still nobody logged on and nothing to do!  And 
       this happens every time MVS wants to enter the wait state, which 
       is very frequent in a machine that's waiting most of the time!   
       The big difference between MVS waking up in a native machine and 
       MVS waking up in an LPAR machine is that the HSB is not shared in
       a native machine, so there is little cost and no contamination   
       for the wake up, but in LPAR machines, with their shared HSB, any
       logical machine wake up can contaminate the current contents of  
       the HSB, causing additional overhead to reload the replaced line.
                                                                        
    Since LPAR management has to execute each logical engine on a real  
    engine, the overhead increases with the total number of logical     
    engines that are defined, and the LPAR management time primarily    
    contributes to uncaptured CPU time.  The TCB time effects primarily 
    result from the changing of lines in the HSB (or CPU cache), which  
    cost more CPU time when the production LPAR is re-dispatched, since 
    it now has to reload the HSB from real storage.                     
                                                                        
    MVS/ESA 4.3 makes the problem go away because the MVS Dispatcher was
    redesigned (and uses what is now called Alternate Wait Management); 
    MVS now looks at its own utilization, and when utilization is low,  
    MVS stops waking up the extra logical CPUs until new work arrives!  
                                                                        
    This problem was originally reported by a Gartner Group "FLASH", but
    that alert did not mention that the problem only occurs in LPARs.   
                                                                        
 3. APAR OY65101 adds a new JES2 option (NEWPAGE=1/ALL) to choose if a  
    new page is counted only for "skip-to-channel-one" (NEWPAGE=1), or  
    if a new page is counted for "skip-to-any-channel" (NEWPAGE=ALL, the
    default, and the old way).  This APAR addresses a long standing need
    to make variable PAGECNT more accurate; however, you should read the
    discussion in Newsletter 23, "MVS/ESA Resource Accounting- PRINTERS"
    on page 22, because PAGECNT is still a poor choice for accounting.  
                                                                        
 4. APAR OY61331 corrects wrong/impossible values in type 14 SMF records
    for multi-volume datasets in fields (SMF14RIN,SMF14NEX,SMF14NER,    
    SMF14NTA,SMF14NTR,SMF14NTU,SMFTIOE4,SMFSRTES) which caused values   
    like 168 extents allocated, 1 track allocated, false PDSE flag, etc.
    That APAR went PE, so see also OY63627.                             
                                                                        
 5. APAR OY65854 reports (without a fix) errors in STARTIME (SMF7xIST)  
    in RMF after applying OY59552.  The error is that STARTIME contains 
    the interval end time instead of the interval startime!  Also, the  
    DURATM (SMF7xINT) may be very small ('0000010F'x = 10 millisec).    
                                                                        
 6. APAR OY65280 corrects invalid data in TYPE24 when a multi-destinated
    SYSOUT data set followed by a normal SYSOUT data set are offloaded. 
                                                                        
 7. APAR OY66531 corrects erratic values in TYPE74 Disconnect and Pend  
    Times.  While the APAR mentions only Monitor II (i.e., type 79 RMF  
    record), and only for Serial Channels, installing this APAR did in  
    fact correct bad values for both Parallel and Serial channels in the
    type 74 RMF record (i.e., Monitor I).                               
                                                                        
 8. APAR OY67681 reports (without PTF yet) that TYPE62 variable DSNAME  
    is incorrect when the component/cluster being opened is the catalog 
    itself.  The first 12 bytes of the name are overlaid in that case.  
                                                                        
 9. Boole and Babbage CMF type 70 records under Amdahl's MDF contain    
    incorrect CPU utilization that is fixed by their correction BAM3760.
                                                                        
10. MVS/ESA allocates secondary extents differently than MVS/XA.  A site
    running BUILDPDB under SAS Version 5, with //WORK block-allocated   
    SPACE=(6144,(100,50)), found the job ran under XA but failed with   
    insufficient work space under ESA.  It turns out that under XA the  
    secondary allocation of 50 blocks used the DCB blocksize, and not   
    the JCL block parameter.  The DCB blocksize after open was 32760,   
    and the job got the space it needed in secondaries of 50*32760 per  
    secondary.  However, ESA (correctly, I believe) always uses the JCL 
    block size for secondaries, and the job only got 50*6144 per        
    secondary, and thus failed for insufficient space!                  
                                                                        
11. After installing PUT 9332, invalid type 70 records are created with 
    no PR/SM section (and thus no observations in MXG TYPE70PR dataset),
    and with invalid data for WAIT times in the TYPE70 data set, and    
    these invalid type 70 records caused IBM's RMF Report program to    
    ABEND 0C9.  These errors are corrected by APAR OY67002 for MVS/ESA  
    4.2.0 thru MVS/ESA 4.3.0.                                           
                                                                        
12. Type 6, 24, and 26 SMF records READTIME can be later than REND time 
    when using the sysplex timer with a non-zero leap second value until
    APAR OY67004 is installed.  IBM uses STCK instruction for READTIME, 
    and the TIME macro for reader end time, but only the TIME macro had 
    proper support for leap-seconds.  APAR OY67004 now causes the STCK  
    instruction to now factor leap seconds into conversion to local.    
    This APAR also indicates that timestamps that used to be all nulls  
    are now going to be formatted as a zero-value packed field; this may
    cause problems since SAS has always input all nulls as a missing    
    value (i.e., the event did not occur), but a zero-value packed field
    would be input as 01Jan1960:00:00:00!                               
                                                                        
13. PTF UY91040 corrupts the Cache RMF Reporter data (size of cache is  
    wrong).  APAR AW01787 corrects the error.                           
                                                                        
14. APAR OW01141 reports SMF/RMF records are not synchronized when they 
    should be, but no PTF is yet available. (4/12/1994: PTF does exist).
                                                                        
15. IBM Washington System Center Flash 94-06, (Internal Use Only),      
    "Release to Release Migration Software Performance Impact" provides 
    an excellent, open discussion of how the recorded CPU time was      
    changed by upgrading several products at one time.  Get your IBM SE 
    to share it with you.                                               
                                                                        
16. APAR PN52658 corrects the wait times in the BatchPipes/MVS Product's
    type 91 SMF record.  Without the APAR, those times are invalid.     
                                                                        
17. APAR PN49692 corrects type 96 (TIRS) SMF record; subtype was 36 vice
    2, and CPU times were five times too large.                         
                                                                        
18. APAR OW02571 reports (no PTF yet) invalid DCOLLECT values for 3390-9
    devices; values in DCVFRESP/DCVALLOC are overreported.              
                                                                        
19. Type 30 interval records are not written for swapped out tasks.     
    This is not new, but just a reminder of a typical TSO session:      
              INTBTIME   INTETIME      SMFTIME                          
               8:23am      8:30am      8:30am                           
               8:41am      9:00am     12:14pm                           
              12:14pm     12:15pm     12:15pm                           
    This TSO user logged on at 8:23, worked until before 8:30.  At 8:41 
    he did a little, but then slept until 12:14, when he logged off.  No
    records were written between 9:00am and 12:14, because the task was 
    swapped out, and no task is swapped in to write the type 30 interval
    accounting records; only when the task has come back into memory    
    will the SMF interval record be written.  Now that we can           
    synchronize type 30s with time of day, summarization of PDB.SMFINTRV
    with workloads defined by job name, account number, etc., becomes   
    feasible, and is under development!                                 
                                                                        
20. IBM Cache RMF Reporter Version 1.5 is required with MVS/ESA 4.3; if 
    Release 1.4 is used, binary zeros are in configuration data fields. 
                                                                        
21. APAR OW03158 implies a new 4-byte Date Opened Field (finally!) will 
    be added to type 14/15 records, but there is no PTF yet, and I can't
    write the MXG code change to support it until there is!             
    Online only update Aug 24, 1994: APAR OW00484 actually added the new
    field, which was supported by MXG Change 12.036, in MXG 12.01.      
                                                                        
                                                                        
IV.   VM Technical Notes                                                
                                                                        
 1. MXG 11.11 has been partially tested under CMS versions of SAS, but  
    the standard BUILDPDB may not compile in a 12MB machine.  The       
    REXXTES6 example was also revised to supply the VMXGINIT invocation.
    Currently, BUILDPDB with the recommendation of Change 11.067 to     
    remove CICS and DB2 processing does successfully execute under CMS  
    SAS.  The installation instructions have not been rewritten for CMS.
                                                                        
 2. SAS Version 6 data libraries created by MVS SAS cannot be read      
    directly by CMS SAS from a volume shared between MVS and CMS.  CMS  
    SAS sites who want to build their PDB under MVS and then access the 
    PDB from CMS for reports/graphs must build the PDB in Version 5     
    format (by specifying LIBNAME PDB ENGINE=V5).  Alternatively, build 
    the PDB under Version 6 in Xport format, (by specifying LIBNAME PDB 
    ENGINE=V6SEQ;), and then import the library into CMS, creating a    
    separate CMS file for each data set in the library, and obviously   
    requires twice the DASD space:                                      
          LIBNAME PDB V6SEQ 'C';                                        
          CMS FD PDB C DSN SYS1.MXG.PDB;                                
    The only other alternative is to use SAS/SHARE on both MVS and CMS  
    to share the PDB.  See SAS Usage Note V6-SYS-SASIO-2172 for details.
                                                                        
V.    CICS Technical Notes                                              
 1. Truncated type 110 Statistics records written by CICS/ESA are now   
    corrected by APAR PN39841.  They were detected by MXG and deleted.  
                                                                        
VI.   SAS Technical Notes                                               
                                                                        
 1. CRITICAL ZAP Z6088203 REQUIRED for MVS sites at TS405 or TS407.     
                                                                        
    Sites with SAS 6.08 at TS405 or TS407 Level (under MVS only) must   
    immediately install Critical Zap Z6088203.  Without this ZAP, very  
    large Data steps (specifically, BUILDPDB's SMF-reading data step)   
    can generate specious MXG ERRORs, such as INVALID OMVS TRIPLET      
    messages, and/or INPUT STATEMENT EXCEEDED RECORD LENGTH conditions, 
    and/or fractional/wrong values for integers.  In all reported       
    occurrences thus far, the job ABENDed, but that is not guaranteed.  
                                                                        
    SAS Maintenance installed in TS405/TS407 for MVS did not initialize 
    numeric variables correctly, and the text of 8203 reads:            
       "when the sum of the lengths of the constants in a DATA step are 
       between 32K and 40K and the number of non-retained numeric       
       variables exceeds 160, it is possible that the numeric variables 
       may contain garbage values when they should be missing."         
                                                                        
    Thus far, the error has occurred only when BUILDPDB has been        
    "tailored" to read additional SMF records.  My untailored BUILDPDB  
    did not produce any error, but adding just one SMF record (albeit   
    complicated) increased the program size enough to cause the failure.
    Nevertheless, I strongly recommend installation of this ZAP at all  
    MVS sites with TS405/TS407 - the cure is easy, the disease fatal!   
                                                                        
*****THIS IS AN ABSOLUTELY CRITICAL ZAP - DO NOT OVERLOOK THIS NOTE**** 
                                                                        
    The ZAP became available for download from SAS Institute on Feb 2,  
    and has corrected the problem at 6 sites, with no induced problems. 
    The logic error in the compiler has been fixed in source in time for
    automatic inclusion in SAS Maintenance Level TS410, due out later   
    this year, so this ZAP will not be needed when TS410 is available.  
                                                                        
 2. The erratic series of SAS errors (NOTSORTED condition when the data 
    had just been sorted, HEADER LENGTH wrong, etc.), that ABENDed once,
    and wouldn't fail again, has finally been nailed down by techs at   
    SAS Institute, because one user, ???  ???????????, at Iowa State    
    University, was finally able to create a repeatable failure!  Zaps  
    Z6076442 or Z6086442 are now available for down loading from SAS    
    and they were on the "second" maintenance tape, TS407.  The actual  
    error was the overlay of bit maps used by SAS to describe where data
    elements were located in the WORK file.                             
                                                                        
 3. When moving SAS Graphics catalogs, the only way to keep the graphs  
    in the same order is to use PROC GREPLAY.  If instead you use PROC  
    DOWNLOAD or CPORT, your graphs will be reordered based on the NAME  
    of the graph, and we can only partially control the name of a graph.
    While you can specify NAME= parameter on the graphics procedure, the
    name you specify is given only to the first graph produced,  If more
    than one graph is produced, the name of subsequent graphs is your   
    NAME suffixed with a number.  PROC DOWNLOAD and CPORT sort graphs in
    collating sequence before moving, so if you have more than 10 graphs
    of the same NAME=, the order becomes NAME NAME1 NAME10 NAME11 NAME2.
    Using PROC GREPLAY to move graphics catalogs is thus recommended!   
      We need to be able to control the names of graphs. Left padding of
      the numbers with zeros, and numbering all names would work, but   
      the ability to specify a GROUP at the same time as the NAME would 
      also help; these suggestions have been made to SAS Institute.     
                                                                        
 4. SAS 6.08 ABEND 0C4 in Function VG2LD at OFFSET 00009A has SAS ZAP   
    Z6087606 now available that corrects the ABEND.                     
                                                                        
 5. SAS 6.08 and 6.07 can enter an SVC Wait state if an invalid VBS data
    record is found as the last record at a concatenation boundary.  SAS
    Usage Note 6810 discusses, and suggests to circumvent by  a) making 
    the file with the bad record the very last concatenation, or  b)    
    processing the individual files separately, or c) specifying on each
    DD statement  DCB=BUFNO=1.  The last circumvention is probably the  
    best, as it inhibits the SAS read-ahead which is the real culprit   
    here, but you do not want to normally specify only one buffer, as it
    will slow down normal processing.  This SAS error is a high-priority
    item, and a ZAP was to be available soon from SAS Institute.        
                                                                        
 6. SAS USER ABEND 315 has occurred in an SMS environment in which Tape 
    Mount Management saw a request for UNIT=TAPE, but converted that    
    request to a DASD allocation (because the data set was expected to  
    be small, and would be copied with many other small data sets from  
    DASD to TAPE later by SMS).  A problem is open at SAS Institute, but
    it's not clear to me that this is a SAS problem, because in adding a
    SPACE=(CYL,(XX,YY)) parameter to the UNIT=TAPE DD works, and thus it
    appears that SMS is not properly allocating the data set!  A better 
    alternative solution is to specify your Storage Class for tape      
    (i.e., the one that will bypass SMS Tape Mount Management).  Still  
    another choice is for your SMS guru to exclude program name SAS*    
    from Tape Mount Management.  This note will change if more is known.
                                                                        
 7. Using an MVS PDSE library instead of an MVS PDS library for your MXG
    SOURCLIB requires SAS ZAP Z6077095 for 6.07, Z6087095 for 6.08 thru 
    TS0405 maintenance; otherwise, you will get ERROR 180s.             
                                                                        
 8. One site received a 'FORMAT MGxxxxx UNKNOWN', even though the job   
    had the //LIBRARY format library properly built and connected.  It  
    turns out the real problem was insufficient memory - increasing the 
    MEMSIZE in CONFIG made the error go away!                           
                                                                        
VII.  IMS Technical Notes - Newsletter TWENTY-FIVE                      
                                                                        
      MXG Position on using only IBM IMS Log Records, updated 28Oct2010 
                                                                        
 1. MXG has always stated that IMS sites must install an IMS monitor to 
    accurately capture resources and responses for IMS transactions; the
    IMS log data written by IBM records only program resources and does 
    not record transaction data for IMS accounting or capacity planning.
                                                                        
 2. MXG currently supports three IMS monitors: BMC's MVIMS, Mainview for
    IMS, previously Boole's IMS Measurement Facility, "IMF", product    
    (supported in MXG member TYPECIMS, from its original name of        
    Control/IMS), and ASG-Landmark's The Monitor for IMS, (member       
    TYPETIMS), and IBM/Candle's IMS Transaction Reporting Facility,     
    "ITRF" product (member TYPEITRF).  These IMS monitors "hook" IMS to 
    capture and record both resource and response measurements for each 
    transaction that are legitimate for accounting, performance tuning, 
    and capacity planning.                                              
                                                                        
 3. To IBM, the IMS log exists only for recovery of databases; it is not
    designed for transaction accounting nor response measurement.  What 
    little resource accounting there is (only CPU and DL/I count, no I/O
    counts), exists only in the Program record, written when a program  
    is de-scheduled, and each Program record contains totals for all of 
    the transactions that were executed by that program schedule.  (IMS 
    Wait-for-Input, WFI, programs can stay up all day and execute many  
    thousands of transactions in one program record!)                   
                                                                        
    Some IMS log records are at the transaction level, but only for the 
    response time, and as there is no unique token in those records that
    associates records with specific transactions, post-processing to   
    assemble transaction events from log records is not guaranteable.   
    This is the heart of the exposure in the post-processing-algorithms 
    of ASMIMSL6.                                                        
                                                                        
       In contrast, in batch and TSO we have the READTIME-JOB token,    
       and in CICS and DB2 we have the NETSNAME-UOWID token with which  
       to identify all records caused by a specific transaction, but    
       no such token is provided in IBM's IMS log records.              
                                                                        
 4. In addition to full support for the three IMS monitors' records, MXG
    has also provided algorithms that attempt, successfully so far, to  
    reconstruct IMS transactions using only the IBM-provided IMS log    
    records, with the ASMIMSL6 Assembly Language program and JCLIMSL6   
    multi-step job.                                                     
                                                                        
    Only a handful of sites ever reported any discrepancies in ASMIMSL6,
    and they tended to be the sophisticated IMS sites with very complex 
    transaction sequences, and they have questioned response measures,  
    and not the resource measures. (And without an independent measure  
    of response, it's hard to show that ASMIMSL6 is actually at fault!) 
    Total CPU time, DL/I calls, and the count of transactions have been 
    correct and usable.  These sites simply discard the transactions    
    with unrealistic response measures (too large or negative), tracking
    to see that the number of discarded transactions is small.          
                                                                        
    Furthermore, IMS SAP accounting and IMS059 Fast Path datasets come  
    from independent log records, and are thus independently usable.    
                                                                        
    Officially, I do NOT have a legal obligation to modify the existing 
    ASMIMSL6 program's post-processing algorithms until IBM provides an 
    auditable and unique per-transaction token in each IMS log record   
    that eliminates the need for that ASM program.  And, even with a new
    unique transaction token, until IBM also provides per-transaction   
    level counts of CPU time, DL/I calls, and physical I/O, even with   
    ASMIMSL6/JCLIMSL6, the IBM IMS log records will never be completely 
    accurate for billing or response investigations.                    
    Fortunately, this has not been issue, since JCLIMSL6/ASMIMSL6 have  
    worked with every IMS Version, including IMS Version 11 in 2010.    
                                                                        
    HOWEVER: ADDED SEP 2014:  ASMIMSL6/JCLIMSL6 was replaced by the new 
    IMS56FA IMS log transaction record.  See TYPEIMST and Newsletter    
    FIFTY-NINE IMS Technical Notes.                                     
                                                                        
VIII. Incompatibilities and Installation of MXG 11.11.                  
                                                                        
 1. Incompatibilities                                                   
                                                                        
 a. MXG's summarization member, %VMXGSUM was changed incompatibly, but  
    it should affect only the very small number of (sophisticated) users
    who have tailored MXG summarization/trending members:               
                                                                        
    If any of these members exist in your USERID.SOURCLIB(s) libraries: 
          ASUMDBDS ASUMDB2A ASUMDOS  ASUMHPCS ASUM70PR                  
          DAILYDSN GRAFDB2  GRAFLPAR TRNDDB2A                           
    or if you use %VMXGSUM in your own report/summarization programs,   
    then you MUST read the details in Change 11.309 and you will need to
    re-tailor your changes.                                             
                                                                        
    The incompatibility is somewhat obscure; to reduce CPU time and to  
    minimize temporary DASD space used during summarization, %VMXGSUM   
    now determines which variables are needed, and keeps only the needed
    variables from the input data set.  The problem arises only if you  
    use the INCODE= parameter (it lets you insert SAS code into the     
    summarization logic, and is used in those nine members), and even   
    then, only if you reference variables in your INCODE= logic that are
    not going to be kept in the output summarized dataset.  In that rare
    case, you must list those un-kept variables in the new KEEPIN= parm.
    The above members in MXG 11.11 contain the needed KEEPIN= statement.
    (If you overlook this note, you still should detect the problem in  
    your testing, because you will normally see UNINITIALIZED VARIABLE  
    messages on the SAS log to alert you to your error!)                
                                                                        
 b. Make sure you are using the CONFIG member from the MXG 11.11 library
    in your JCL, either with the MXGSAS JCL Procedure, or on your EXEC: 
        // EXEC SAS,CONFIG='MXG.V1111.SOURCLIB(CONFIG)'                 
    You will get many, strange syntax errors (ERROR 180 or 200) if you  
    do not use the MXG 11.11 CONFIG member.                             
                                                                        
    If you are migrating to MXG Version 11.11 from MXG Version 9.9 or   
    earlier, AND you have tailored your MXG installation (with EX...  or
    IMAC.... members), you must read the MXG 10.10 compatibility section
    in member CHANGESS; find the text "member=CHANGE10" and read on!    
                                                                        
 c. MXG Version 11.11 requires SAS Version 6.08 at maintenance TS407,   
    plus SAS Zaps Z6088203 and Z6086442 for MVS and CMS.  For WINDOWS,  
    SAS 6.08 at TS407 is required.  For all UNIX, except for AIX, SAS   
    6.09 is required.  For AIX, the second maintenance to 6.09 will be  
    required.  For OS/2, SAS 6.10 will be required.  (Both AIX and OS/2 
    do not currently properly support VBS record processing; their fixes
    are due out this summer.)  MXG has been tested error-free with the  
    above SAS versions, and I strongly suggest you ensure that your SAS 
    System is at the above level of SAS maintenance.  (While most of MXG
    may execute successfully with lower maintenance, you may encounter  
    known errors if you are not at the above level.)                    
                                                                        
 d. Observation counts may change in PDB.JOBS and PDB.NJEPURGE because  
    of Change 11.226.  More observations may be seen in PDB.TYPE74 due  
    to Change 11.170.                                                   
                                                                        
 2. Installation and re-installation procedures are described in detail:
    in member INSTALL, and sample JCL is in member JCLINSTL.  Summary:  
     a. Install member MXGSAS as JCL Procedure MXGSAS in your PROCLIB.  
     b. Allocate a 78-cyl PDS: MXG.V1111.MXG.SOURCLIB, and use IEBUPDTE 
        to read the MXG tape to create the 2000+ member Source Library. 
     c. Allocate a 1-cyl PDS:  MXG.V1111.USERID.SOURCLIB for your site  
        "Installation Tailoring" Source Library.  Installation specific 
                                                                        
        tailoring (like telling MXG your shift hours, which performance 
        groups are TSO, CICS, etc.) is done by copying and modifying MXG
        source members into V1111.USERID.SOURCLIB.                      
     d. Allocate a 1-cyl SAS Data Library:  MXG.V1111.MXG.FORMATS and   
        execute SAS to create the library of Formats required by MXG.   
     e. If this is the initial install of MXG, tailor these members into
        your MXG.V1111.USERID.SOURCLIB tailoring library:               
          IMACACCT (Account Length),                                    
          IMACSHFT (Shift Definitions),                                 
          IMACWORK (Performance Group to Workload mapping), and         
          IMACSPIN (for BUILDPDB).                                      
        Each IMAC member is self-documenting, and IMACAAAA is the index 
        of all of the IMACs.  You should at least scan IMACAAAA to see  
        the acronyms MXG uses for the many products MXG supports.       
     e. If re-installing MXG, copy your existing USERID.SOURCLIB library
        members into the MXG.V1111.USERID.SOURCLIB. Then compare your   
        IMACs with those that were changed (see the alphabetical list of
        changed members in member CHANGES).  If any members in your     
        MXG.V1111.USERID.SOURCLIB were changed, you must reinstall your 
        site's tailoring for that IMAC, starting with the IMAC member   
        from the MXG 11.11 Source Library.                              
     f. EDIT and submit member JCLTEST6 to verify that your tailoring   
        did not create any errors.                                      
     g. EDIT and submit JCLPDB6 to create a Daily PDB for testing.  Or  
        use the TYPE.... members to process specific data sources, use  
        the ANAL.... members for report examples, the GRAF.... members  
        for SAS/GRAPH reports.                                          
                                                                        
     You have now installed MXG 11.11 in its own set of libraries.  When
     parallel testing is complete and are ready to implement MXG 11.11  
     in production, rename your three current MXG Production Libraries  
     (MXG.MXG.SOURCLIB, MXG.USERID.SOURCLIB, and MXG.MXG.FORMATS) to    
     (MXG.BACK.MXG.SOURCLIB, MXG.BACK.USERID.SOURCLIB, MXG.BACK.MXG....)
     and rename the MXG.V1111.x.y libraries to their Production names!  
                                                                        
     Again, detailed installation instructions are in member INSTALL    
                                                                        
Always read comments in the CHANGES member for compatibility issues, as 
well as for any last minute changes.                                    
                                                                        
Whenever you install changes or test a new version of MXG (or even your 
own reports), be extra careful to look on the SAS log for any real error
conditions. Search for all occurrences of "ERROR:" and  "ERROR :"  and  
"UNINITIALIZED" and "NOT CATLGD", as they may indicate a serious error. 
                                                                        
A PROC PRINT and a PROC MEANS of each new MXG-built SAS dataset can help
you to understand their contents, and should be used to examine any     
unusually large, negative, or suspicious values.  Print all variables in
the dataset, and read the variable's descriptions in its ADOC member.   
                                                                        
IX.   Documentation of MXG Software.                                    
                                                                        
Member CHANGES identifies the Version and Release of MXG Software, and  
describes all changes made in that Release.  The text of each change    
names the members that were added or altered by that change.  Member    
CHANGES is designed to be read online (with SPF BROWSE), so that you can
search for specific product name references (CICS, MVS/ESA, etc.), or   
the MXG member name or product acronyms.                                
                                                                        
Member CHANGESS contains ALL changes in ALL versions of MXG.            
                                                                        
Member NEWSLTRS contains the text of all newsletters.  You can search   
NEWSLTRS for product name or acronym to find the technical notes, APARs,
                                                                        
etc., from all MXG newsletters.  Since the Change Log portion of each   
newsletter is in member CHANGESS, they are not repeated in NEWSLTRS.    
The MXG Technical Newsletter is typically published twice a year, with  
one printed copy sent to each licensed site, and it describes changes   
and enhancements to the software, provides APARs and PTFs affecting MXG 
users, and provides technical papers of interest to MXG users.          
                                                                        
Member DOCVER lists alphabetically ALL datasets and variables that are  
built by this MXG Software Version.                                     
                                                                        
Members DOCVERnn are the "delta-documentation" between MXG versions, and
list only those datasets and variables that were added/deleted/changed  
by version "nn".                                                        
                                                                        
Members ACHAPxxx are the text chapters from the 1984 MXG Guide and the  
1987 MXG Supplement, to which the text of newsletters and changes has   
been added.  At present, these chapters are very rough; in a few cases  
the chapter has actually been completed and revised, but most of these  
chapters delivered in MXG 11.11 are little more than a concatenation of 
the original text, and there are no figures nor tables.  This is clearly
work in progress, but at least the old books are now machine readable!  
When all 42 chapters are completely revised and updated in the source   
library, I will decide if any will also be made available in printed    
form, but the primary source of all future documentation will be the MXG
source library itself, which can now be updated when changes occur!     
                                                                        
Members ADOCxxxx are what were in Chapter FORTY, and should be the first
place you look for information about MXG variables and/or datasets.  The
ADOCxxxx members alphabetically describe each dataset and all variables 
that are created by product xxxx, the instructions on how to enable that
product, bibliography of the vendor documentation, sample PROC PRINT and
PROC MEANS of real datasets, references to MXG reports that use these   
datasets, and the MXG member names that you use to process that product.
There is an IMACxxxx member for every product supported by MXG.  Once   
you know the xxxx suffix for a product, you then know the names of all  
of the MXG members for that product:                                    
                                                                        
  IMACxxxx - Defines record IDs, and "_K,_L" macros for product xxxx.   
  ADOCxxxx - "Chapter FORTY" style dataset and variable documentation.  
  VMACxxxx - The "real" source code member, often extensively commented.
  TYPExxxx - Standalone member to test or process product xxxx records. 
  ASUMxxxx - Summarization example (only for some products)             
  TRNDxxxx - Trending example (only for some products)                  
  ANALxxxx - Reporting/analysis example (only for some products)        
  GRAFxxxx - SAS/GRAPH report example (only for some products)          
  EXyyyzzz - OUTPUT exit for each dataset.  There can be more than one  
             dataset per product.  The EX member name suffix yyyzzz is  
             the same as the suffix of "_L" and "_K" macros defined in  
             IMACxxxx for the product.  See further discussion under    
             "Using the MXG Exit Facilities" in ACHAP33.                
                                                                        
Member IMACAAAA is an index of all IMACs, and is the best place to begin
to find what xxxx suffix Merrill chose for which product! You can often 
find additional documentation by searching members NEWSLTRS or CHANGESS 
for the xxxx suffix.                                                    
                                                                        
Finally, remember that MXG is source code, so you can often find your   
answer by BROWSING the source members, especially the VMACxxxx, ANALxxxx
members.  The MXG Variable name is often the DSECT's field name, and if 
not, the vendor's field name is often in adjacent comments in the INPUT,
so you can cross reference to the vendor's documentation of their data! 
                                                                        
X.    Changes Log                                                       
                                                                        
--------------------------Changes Log---------------------------------  
                                                                        
 You MUST read each Change description to determine if a Change will    
 impact your site. All changes have been made in this MXG Library.      
                                                                        
 Member CHANGES of the MXG SOURCLIB will always be more accurate than   
 the printed changes in a Newsletter, because the software tapes are    
 created after the newsletter is sent to the printer!                   
                                                                        
 Member CHANGES always identifies the actual version and release of     
 MXG Software that is contained in that library.                        
                                                                        
 The actual code implementation of some changes in MXG SOURCLIB may be  
 different that described in the change text (which might have printed  
 only the critical part of the correction that can be made by paper).   
                                                                        
 Scan each source member named in any impacting change for any comments 
 at the beginning of the member for additional documentation, since the 
 documentation of new datasets, variables, validation status, and notes,
 are often found in comments in the source members.
