Error description

  • z/OS MQ receiver-type channels go directly into STOPPED/DISABLED
    state immediately, even when they're in a stop requested state
    with the actual stop pending. This is inconsistent with the
    distributed versions of MQ.

    * PROBLEM DESCRIPTION:                                         *
    * Receiver and Cluster-Receiver channels may report as STOPPED *
    * status while still STOPPING.                                 *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    When a Receiver or Cluster-Receiver channel is stopped from the
    Receiver-side, a DISPLAY CHSTATUS command for the channel may
    immediately show the Receiver channel as being in STOPPED
    status, even though the channel is still active as viewed from
    the Sender side.
    

Problem conclusion

  • Processing has been amended to correctly show that a stopping
    Receiver or Cluster-Receiver channel is in STOPPING state until
    the channel has stopped.
