APAR status

• Closed as program error.

Error description

• Users having applied PQ93475/UK00453 may experience the
  following problems:
  1) S0C4 abends in IRTXRInn during a restart if the option
     REATTACH=YES has been specified;
  2) ATTACH occurring incorrectly when an application attempts
     a LINK to DFSRRC00;
  3) S306 abends if the JCL step should be authorized;
  4) Problems with IRTSAMP members including the sample usermods.
     PRF should also be changed to improve handling of restarts
     when the application has not issued symbolic CHKP calls
  with unique non-blank characters to reduce the number
  of U0102 abends.
  5) The bypass checkpoint processing option does not
  get enabled if the customer specified BYPCHKP=YES.

  Users having applied PQ93475/UK00453 may experience the
  following:
  1.ABEND0C4 in IRTXRI00 during a restart if the option
  2.REATTACH=YES has been specified;
  3.ATTACH occurring incorrectly when an application attempts
    a LINK to DFSRRC00.
  4.S306 abends if the JCL step should be authorized;
  5.Problems with IRTSAMP members including the sample usermods.
  6.The bypass checkpoint processing option does not get enabled
    if the customer specified BYPCHKP=YES.
  

Problem conclusion

• Program Restart is being changed as follows:
  
  1.The requirement to install usermods which update IMS source
    for modules DFSZSC00 and DFSZSR00 is being removed.
  2.Support for the IMS Online Reorg Facility (ORF) is being
    added. The support allows Batch Message Regions (BMP's)
    using database(s) reorganized by IMS ORF to be suspended
    and then automatically resumed when ORF has completed the
    reorganizations without terminating the job step and without
    operator intervention.
  3.Program Restart will use the time stamp restart checkpoint
    ID instead of the 8-character symbolic ID whenever possible
    in case the application program was not generating a unique
    ID for every symbolic CHKP call made.
  4.Program Restart will automatically restart applications based
    on a table of abend completion codes added to the inclusion
    options data set.
  5.During a restart, Program Restart users could experience
    intermittent S0C4 abends in module IRTXRI00 after applying
    maintenance for PQ93475.
  
  6.After applying the maintenance for PQ93475, users with
    applications linking to DFSRRC00 and also specifying
    REATTACH=YES could go into a long wait after the initial
    PRF ATTACH.
  7.S306 abend in IRTUPX00 could occur if the job step is intended
    to be APF authorized.
  8.After applying the maintenance for PQ93475, the bypass
    checkpoint processing option is not enabled for users
    specifying REATTACH=YES and BYPCHKP=YES.
  
  This APAR also updates documentation in the User's Guide.
  Before applying this maintenance, customers will need to make
  sure the SMP/E ++RESTORE operation has been performed for
  PRF usermods MRT510D, MRT610D, MRT710D, MRT810D and MRT910D.
  
  For IMS Version 5 customers, if usermod MRT510D has been
  applied to any IMS Version 5 SMP/E target zones, then a
  ++RESTORE for this usermod will need to be performed.
  
  For IMS Version 6 customers, if usermod MRT610D has been
  applied to any IMS Version 6 SMP/E target zones, then a
  ++RESTORE for this usermod will need to be performed.
  
  For IMS Version 7 customers, if usermod MRT710D has been
  applied to any IMS Version 7 SMP/E target zones, then a
  ++RESTORE for this usermod will need to be performed.
  
  For IMS Version 8 customers, if usermod MRT810D has been
  applied to any IMS Version 8 SMP/E target zones, then a
  ++RESTORE for this usermod will need to be performed.
  
  For IMS Version 9 customers, if usermod MRT910D has been
  applied to any IMS Version 9 SMP/E target zones, then a
  ++RESTORE for this usermod will need to be performed.
