JR52469: CWWBE0074E OCCURS WHEN YOU SEND MULTIPLE REQUESTS THAT HAVE THE SAME CORRELATION INFORMATION

8.5.0.2-WS-BPM-IFJR52469
8.5.5.0-WS-BPM-IFJR52469
Version 8.5 Refresh Pack 7 for the IBM Business Process Manager products

APAR status

• Closed as program error.

Error description

• If simultaneous requests with the same correlation set are sent,
  and there is no process instance waiting for this correlation
  set yet, both requests might try to create a process instance at
  the same time with the same correlation information.
  
  The second request might fail with the CWWBE0074E error if the
  request is processed before the transaction of the first request
  completes.
  
  The exact exception that causes the error varies depending on
  the database type used. You might see the
  com.ibm.websphere.ce.cm.DuplicateKeyException or a more generic
  exception like com.microsoft.sqlserver.jdbc.SQLServerException.
  The exception details indicates the problem of inserting a
  duplicate key in the correlation set table
  (CORRELATION_SET_INSTANCE_B_T ).
  

Local fix

• Modify the application to ensure that requests that might
  create a process instance and use the same correlation
  information are processed sequentially.
  

Problem summary

• Because a correlation set must uniquely identify a process
  instance, only the first of the requests succeeds and a
  CWWBE0074E occurs for the second request.
  

Problem conclusion

• A fix is/will be available for IBM BPM V8.5.5 that retries
  processing the second request so that this request can be
  received by the newly created process instance.
