Error description

Root cause is application is listening in the Servant Region
rather than Control Region due to WebSphere code defect.

Problem summary


    

  • ****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server V8.5 for z/OS                        *
****************************************************************
* PROBLEM DESCRIPTION: Attempting to process a message         *
*                      within a BMT MDB results in a           *
*                      SystemException being thrown and the    *
*                      message rolled back.                    *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
Using the IBM MQ JMS provider would normally result in the
message listener running in the Control Region, while the MDB
would be running in the Servant Region.  However, the JMS
provider was mis-identified as being non-IBM.  This caused all
listener and MDB processing to be deferred to the Servant
Region, resulting in the failure of the BMT processing.

    



Problem conclusion


    

  • Change to correctly identify the IBM MQ JMS Provider.
