JR44329: EVENT PROGRESS COUNTER IS RESET TO 0 FOR CEI EVENTS, WHICH LEADS TO EXCEPTION CWMRT0074E IN IBM BUSINESS MONITOR

Version 8.0.1 Fix Pack 1 for the IBM Business Process Manager products
Version 7.5.1 Fix Pack 2 for the IBM Business Process Manager products

APAR status

• Closed as program error.

Error description

• The event progress counter is used to indicate the position of
  the current navigation step in the execution order of all
  navigation steps of the same process instance. If an exception
  occurs while the process is waiting to continue the navigation,
  it can happen that the counter is reset to 0 by mistake.
  
  These counters are stored in CEI events using these 2 elements:
    <bpc:eventProgressCounter>0</bpc:eventProgressCounter>
    <bpc:eventLocalCounter>1</bpc:eventLocalCounter>
  
     In case IBM Business Monitor is used, it will not be able to
  process these events with the wrong event progress counter
  correctly, because they appear to be monitored out of order.
  This results in an exception:
  "CWMRT0074E: An event was received out of order.  The event
  will be put on the failed event queue."
   Monitoring Model ID: MyMonitorModel
  Monitoring Model Version: <version #>
   Root Instance ID: <Process Instance ID>
   Current Event ID: 32,688
   Current Event Sequence Index:
  000000000000000000000:000000000000000000001
   Prior Event Sequence Index:
  000000000000000000004:000000000000000000007
  
  The indexes mentioned match up with the event progress and local
  counters. When these are out of order due to this issue then IBM
  Business Montior will throw this error if the two events are not
  received within a certain period of time.

  Problem Summary:
  The event progress counter is used to indicate the position of
  the current navigation step in the execution order of all
  navigation steps of the same process instance. In some
  exceptional cases, it can happen that the counter is reset
  to 0 by mistake.

  Problem Conclusion:
  This fix ensures that the event progress counter is not set to 0
  in these exceptional cases.
