JR52069: DURABLE MESSAGES ARE NOT DELIVERED TO ALL INSTANCES OF AN INTERMEDIATE MESSAGE EVENT IN A MULTI-INSTANCE LOOP

8.0.1.1-WS-BPM-IFJR52069
Version 8.5 Refresh Pack 6 for the IBM Business Process Manager products

APAR status

• Closed as program error.

Error description

• If an intermediate receive message event that has the Durable
  Subscription option selected  and the Consume Message option
  cleared is in a multi-instance loop, the durable message is not
  delivered to all instances of the event.
  
  If the message is received before the multi-instance loop is
  activated, it is only delivered to one instance of the message
  event. If the multi-instance loop is activated before the
  message is received, the message is delivered to all message
  events in a waiting state but not to intermediate message events
  that are activated after the message is received.
  

Local fix

Problem summary

• If multiple instances of a multi-instance loop that have an
  intermediate message event are activated, each instance of the
  intermediate message event has the same event ID. IBM BPM
  assigns a unique wait ID to each instance of the intermediate
  message event, but this wait ID is not reflected correctly in
  the query that determines whether a durable message is available
  when an intermediate message event is activated. Therefore, IBM
  BPM concludes that the message has already been delivered if the
  second or third instance of an intermediate message event is
  activated.
  

Problem conclusion

• A fix is/will be available for IBM BPM V8.0.1.1 that modifies
  the <find-durable-messages-for-event-query> so that it reflects
  the wait ID when it checks whether a durable message is
  available for an intermediate message event.
