 1. Text:                                                               
                                                                        
III. MVS, a/k/a z/OS, Technical Notes.                                  
                                                                        
 6. APAR OA50393 corrects RMF Type 78 data that can have incorrect      
    CHIPDs in the Channel Path detail when CHPIDs are taken offline.    
                                                                        
 5. APAR OA50395 corrects the value in SMF 70 MXG variable SMF70MTTT the
    SMT Mode Multithreading Idle Time, which was previously accumulated 
    but now contains the correct interval value. Note that the correct  
    variable name SHOULD have been SMF70MTIT, and that name is in the   
    label for SMF70MTTT.                                                
                                                                        
 4. z/OS 2.2 APAR PI69487 corrects the excessive response time for TSO  
    reported in RMF TYPE72GO elapsed time because each SDSF session's   
    elapsed time was included in the elapsed time of completed TSO      
    transactions.                                                       
                                                                        
 3. RMF Type 74 subtypes went from 1-6,8 to only 1, 5, 8, when RMF III  
    Monitor was not started on that system.                             
                                                                        
 2. Increased CPU Time in JES2 address space (two to three times) when  
    migrating from z/OS 2.1 to z/OS 2.2 was eliminated by APAR OA50777, 
    a two part fix that also requires RSM APAR OA50806.                 
                                                                        
 1. New JES JOB Correlator field, SMF30COR and SMF26JCR are each 64-byte
    tokens that are unique for each job, and currently contain printable
    text  J0029999 SYSPLEXA CF41F7ED .......: (JCTJOBID, SYSPLEX, token)
    in the first 32 bytes, and blanks in the last 32 bytes (which can be
    populated with local information).                                  
                                                                        
    The fields are populated for Jobs and TSO sessions and full function
    STCs, but all OMVS type 30 records type 30s for these JOB/STCs that 
    start prior to JES startup finish, known as "Early Address Spaces"  
    or "Early ASIDs", will all contain hex zeros in all 64 bytes.

    It's VERY unclear of the use since the total length of 64 bytes is  
    more than double the 24 bytes need for READTIME  JOB  JESNR which   
    have always uniquely identified all records from a job, and those   
    fields are in many more SMF records than just the 26 and 32.

VI.  SAS Technical Notes.                                               
                                                                        
 1. SAS 9.4 datasets can NOT be read with SAS 9.2 or earlier SAS if the 
    9.4 default option EXTENDOBSCOUNTER=YES (alias EOC=YES) was used.   
    This INCOMPATIBILITY is documented in SAS Note 49496, with message: 
      ERROR: FILE xxx not compatible with this SAS version.             
    on the log, BUT THE RETURN CODE IS ZERO.                            
    The SAS Note 49496 lists these possible circumventions              
     Reading (a 9.4 dataset created with EOC=YES default) with SAS 9.2  
     or earlier:                                                        
     -In order to read this data set with SAS 9.2 or earlier, you must  
      do one of the following (both also require 9.3 or 9.4):           
      -Using SAS 9.3, do one of the following:                          
       -Re-create the data set with the data set option EOC=NO, as shown
        on the Full Code tab above.                                     
       -Create a transport file using PROC CPORT and then, in SAS 9.2,  
        use PROC CIMPORT to read it.                                    
      -Using SAS 9.4, do one of the following:                          
       -Re-create the data set with the SAS system option               
        EXTENDOBSCOUNTER=NO or its alias EOC=NO.                        
       -Create a transport file using PROC CPORT and then, in SAS 9.2,  
        use PROC CIMPORT to read it.                                    
    Creating a 2,500,000,000 observation data with EOC=NO resulted with 
    these observed impacts:                                             
     -SAS log creating the dataset has  WORK.DATA1 HAS . OBSERVATIONS.  
     -PROC CONTENTS shows OBSERVATIONS . on the top line; details are   
       PAGES=107,332, MAX OBS Per Page=20963, 1st Page obs=20625        
       which produces count of 107331*20963+20625=2,250,000,373.        
     -PROC MEANS shows 2,500,000,000 observations

 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 always identifies the actual version and release of     
 MXG Software that is contained in that library.                        
                                                                        
 The CHANGES selection on our homepage at http://www.MXG.com            
 is always the most current information on MXG Software status,         
 and is frequently updated.                                             
                                                                        
 Important changes are also posted to the MXG-L ListServer, which is    
 also described by a selection on the homepage.  Please subscribe.      
                                                                        
 The actual code implementation of some changes in MXG SOURCLIB may be  
 different than described in the change text (which might have printed  
 only the critical part of the correction that need be made by users).  
                                                                        
 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.
