PH64525: FOR COUPLING FACILITY ABENDS MQ MAY NOT DUMP THE STRUCTURES REQUIRED FOR PROBLEM DIAGNOSIS

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• This APAR is taken to ensure that MQ includes necessary
  CF-related structures when dumping. This should include the
  application structures that host MQ shared queues.
  

Local fix

• Not applicable.
  

Problem summary

• ****************************************************************
  * USERS AFFECTED: All users of IBM MQ for z/OS Version 9       *
  *                 Release 2 Modification 0 and Release 3       *
  *                 Modification 0                               *
  ****************************************************************
  * PROBLEM DESCRIPTION: A 5C6 abend was encountered while       *
  *                      opening a shared queue. The resulting   *
  *                      dump did not contain the CF structure   *
  *                      associated with that shared queue.      *
  ****************************************************************
  5C6-00C5xxxx abends currently dump the CSQ_ADMIN and CSQSYSAPPL
  structures. As these abends often occur under the structure task
  associated with a different structure, the associated
  application structure should be dumped.
  

Problem conclusion

• The code has been modified to ensure that the CF structure
  associated with the task is dumped during such abends, and
  others taking place on a structure task. This will aid in
  diagnosing the problem more effectively and provide users with
  the vital information to resolve the issue in the future.
