PH67349: STATQ(ON) RESET TO OFF WITH FALLBACK AND REMIGRATE

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• The queue manager STATQ attribute was ON but after START QMGR
  BACKMIG was executed, the STATQ was changed to OFF. For a change
  in command level, QMGR start up in CSQMERST decides to recreate
  the QMGR object (MMMS). To do this it queues a request to call
  CSQMNMMS. CSQMNMMS sets defaults for each of the QMGR object
  attributes. It then locates the old QMGR object, and copies
  values from it into the new one as appropriate. The problem is
  that the STATQ value is never copied from the old QMGR object.
  This leaves it at the default value which is OFF. This problem
  occurs for every migration, forward or backwards.

  * PROBLEM DESCRIPTION: The status of the STATQ attribute on    *
  *                      the queue manager is not correctly      *
  *                      preserved when performing forward or    *
  *                      backward migration across MQ versions.  *
  ****************************************************************
  While object migration occurs during both forward and backward
  migration, the queue manager object (MMMS) containing the STATQ
  attribute is recreated during startup. The recreation process
  does not copy the STATQ value from the previous instance,
  resulting in it being reset to its default value of OFF.
  

Problem conclusion

• The code has been changed to ensure the STATQ status from the
  previous queue manager object is correctly copied into the newly
  created object during migration.
