Error description

• Migration to IBM MQ 9.4 experienced an abend where the dump
  title is: ABN=5C6-00D400AD,U=SYSOPR ,C=MQ900.940.DMC
  -CSQIERS3,M=CSQ GFRCV,LOC=CSQILPLM.CSQIERS3+00001868
  
  The queue manager abended with: CSQV086E QUEUE MANAGER ABNORMAL
  TERMINATION REASON=00D96001
  
  The code was trying to see if a queue has CAPEXPRY coded in the
  CUSTOM attribute to convert it to the new CAPEXPRY parameter.
  
  A queue object was encountered that had been defined years ago
  and still had an internal version of "0" rather than the current
  version "1". The code should handle both versions of an object
  correctly.
  
  In the dump, Register 2 from IPCS ST FAILDATA points to the
  object the code is working with. The name of the queue object is
  visible in storage in the dump IPCS browse mode.
  

Local fix

• ALTER the description field of the queue definition to cause the
  object to be remade at the newer version of the control block.
  
  If there are many objects that were defined many years ago (for
  example prior to MQSeries 5.2), then you can create a list of
  queue definitions with CSQUTIL SDEFS or MAKEDEF. The output has
  DEFINE commands with NOREPLACE. You can do a mass change to
  either make the commands be an ALTER command, and alter the
  description field, or a DEFINE command with REPLACE instead of
  NOREPLACE.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of IBM for z/OS Version 9          *
  *                 Release 4 Modification 0                     *
  ****************************************************************
  * PROBLEM DESCRIPTION: After migrating from an older release   *
  *                      with queue and topic objects defined    *
  *                      and last updated from before the CUSTOM *
  *                      attribute was added, ABEND5C6-00D400AD  *
  *                      may occur, or incorrect CAPEXPRY values *
  *                      may be set.                             *
  ****************************************************************
  The processing of queue and topic objects does not check the
  internal version of an object. For objects defined/last updated
  before the CUSTOM attribute was added, this results in the
  incorrect processing of the CUSTOM attribute that is not
  initialised in storage, which results in the incorrect value
  being set to CAPEXPRY, or a queue manager abend on start up.
  

Problem conclusion

• The code has been corrected to check flags to ensure the correct
  processing is run.
