Error description

  • If a cluster queue is set to PUT(disabled) and messages
    are in transit the target queue manager can throw an FDC
    "Incorrect application process opener context stored in
    MQopen for MQPUT" or the cluster channel to this queue
    manager may be terminated.
    .
    FDC:
      Probe Id   :- QS220012
      Component  :- qslHandlePut
      Comment1   :- Incorrect application process opener
                    context stored in MQopen for MQPUT
    

Local fix

Problem summary

  • Channel termination and occasionally
    creation of FDC with probeID 'QS220012' (Component
    qslHandlePut) happen when PUT(disabled) on a cluster
    queue is performed while messages are in transit. The
    target cluster queue and the SCTQ of the target QMGR
    have to reside on different queue servers. No DLQ has
    to be configured on the target QMGR. There is another
    cluster queue like the target queue in the cluster.
    The likelihood of FDC creation increases when the
    queue servers on target QMGR manage many queue opens.
    

Problem conclusion

  • Problem has been solved. After the cluster
    queue is PUT(disabled) the messages are rerouted to the other
    cluster queue without channel termination.
    

Temporary fix

  • Assign the cluster queue and the SCTQ of the
    target QMGR to the same queue server.
