APAR status

• Closed as program error.

Error description

• When using MQ as the messaging provider for JMS2.0
  applications, handles to MQ destinations can be held open
  after JMSContexts are closed, resulting in increasing open
  input count values for MQ queues.

Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server running JMS2.0 applications with     *
  *                  IBM MQ as the messaging provider            *
  ****************************************************************
  * PROBLEM DESCRIPTION: open handles to MQ queues build up      *
  *                      when the queues are used by JMS2.0      *
  *                      applications in WebSphere Application   *
  *                      Server                                  *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When a JMS2.0 application is running within WebSphere
  Application Server V9, using IBM MQ as the messaging provider,
  the number of open input or output count of the queues used by
  the application can build up. If the application closes the
  JMSContext objects it uses but does not explicitly close any
  consumer or producer objects, then the handles to the
  underlying queues can remain open.
  

Problem conclusion

• The fix for this APAR is currently targeted for inclusion in
  fix pack 9.0.0.4.  Please refer to the Recommended Updates
