PI05897: DIS QC CLUSTER CLUSQMGR DEFPRESP FROM A DISTRIBUTED QM SHOWS AN INCORRECT DEFRESP WHEN FULL REPORSITORY IS IN A Z/OS

APAR status

• Closed as program error.

Error description

• A cluster queue is defined, with two instances of the queue in
  the full repository in a QMGR in z/OS. After you execute an
  ALTER command when a new queue is created, a display qcluster
  in any of the partial repositories shows an incorrect DEFRSEP
  value for the queue:
  
  DIS QC(IMS8GENQ01IN) DEFPRESP CLUSTER CLUSQMGR
  
  AMQ8409: Display Queue details.
   QUEUE(IMS8GENQ01IN)                     TYPE(QCLUSTER)
   CLUSTER(LOSOTROS)                       CLUSQMGR(QCM8)
   DEFPRESP(30978)
  
  However, if you check the queue in the z/OS queue manager where
  the local queue is, the parameter is ok.
  
  The MQLO is being used to obtain sDefPResp instead of the MQAO.

  *                      clustered qalias and qremotes hosted    *

  ****************************************************************
  When altering a clustered queue CSQMQCLU will generate a PCF
  message for the SYSTEM.CLUSTER.COMMAND.QUEUE in order for the
  repository manager to update the cache.
  However in the case of a clustered QALIAS or QREMOTE the value
  is taken from the MQLO.sDefPResp rather than the MQAO or MQRO
  and is likely to result in an invalid value for the DEFPRESP in
  the cache, which will be propagated to other queue managers in
  the cluster. When displaying the DEFPRESP on a distributed queue
  manager this invalid value is visible, although on z/OS only
  allowable values are displayed.
  

Problem conclusion

• CSQMQCLU has been changed to use the correct control blocks.
