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. On Fix Central (http://www.ibm.com/support/fixcentral), search for JR52469: 1.
