  • Closed as program error.

Error description

  • When the USEDLQ channel attribute is altered on a cluster
    receiver channel, the value is not replicated across the
    cluster, and so is not  reflected in the corresponding
    cluster queue manager objects.
    .
    Additional information and symptoms:
    As an example, a CLUSRCVR has USEDLQ(NO) set, but due to this
    bug, the auto-defined CLUSSDR still has USEDLQ(YES) as shown
    by the MQ command
      DISPLAY CLUSQMGR(*) CHANNEL(chlname) CLUSTER(clusname) USEDLQ
    .
    Because of this unexpected USEDLQ setting, messages go to the
    Dead Letter Queue ( DLQ ) unexpectedly.

    ****************************************************************
    The USEDLQ channel attribute was altered on a cluster receiver
    channel, but due to a defect in the queue manager code, the
    changed value was not reflected in corresponding
    cluster queue manager objects.
    

Problem conclusion

  • The defect has been fixed and the USEDLQ attribute is now
    replicated as necessary through the cluster.
    
    This APAR is a route of IT29944.
