APAR status

  • Closed as program error.

Error description

  • When an undercover agent (UCA) is fired, all waiting and
    matching intermediate message events are triggered by that
    message. If a business process definition (BPD) instance is in
    the failed state, the waiting intermediate message events are
    not notified and the messages are discarded even if an
    intermediate message event has durable message subscription
    enabled. The token on such an intermediate message event does
    not move forward after repairing and resuming the failed
    instance although a matching UCA has been fired before.
    

Local fix

Problem summary

  • If a BPD instance is in the failed state, all message events are
    discarded and not delivered to the waiting intermediate message
    events, even if an intermediate message event has durable
    message subscription enabled.

Problem conclusion

  • A fix is planned to be made available for IBM BPM V7.5.1.2 that
    retains UCA message events for intermediate message events that
    have durable message subscription enabled while a BPD instance
    is in the failed state until the instance is resumed and
    running in active state again.  At that time, the retained
    message events are delivered to the waiting intermediate
    message events.
