    * PROBLEM DESCRIPTION:                                         *
    * When event messages are enabled, if the system event queue   *
    * is defined as an alias queue to a topic, the put processing  *
    * to the QAlias may fail to put the message to the             *
    * subscribers.                                                 *

    * RECOMMENDATION:                                              *

    ****************************************************************
    When the event message is being put to the event queue, in the
    case where it is a QAlias which targets a topic, the ASID of the
    message buffer of the event message is set to the application
    address space. However the message buffer is actually within the
    queue managers address space, which may result in the put of the
    event message failing, with MQRC_BUFFER_ERROR (MQRC 2004).
    

Problem conclusion

  • Event message processing has been changed for this scenario, to
    use the correct ASID for the message buffer, when putting the
    event message to a topic in this scenario.
