PK94588: SIB MEDIATION ON MQSERVER STOPS WORKING AFTER APPLICATION REINSTALL

Fixes are available

APAR status

Closed as program error.

Error description

A mediation on a queue point defined on an MQServer stops
working after an application is installed/uninstalled, or a
BUS configuration reload occurs.  The following FFDC is logged:

Exception = java.lang.ClassCastException
Source =
com.ibm.ws.sib.processor.impl.DynamicConfigManager.refreshDestin
ations
probeid = 1:134:1.25.1.1
Stack Dump = java.lang.ClassCastException:
com.ibm.ws.sib.processor.impl.RMQConsumerKey incompatible with
com.ibm.ws.sib.processor.impl.JSConsumerKey
at
com.ibm.ws.sib.processor.impl.mediation.ActiveMediation.stop
(ActiveMediation.java:380)
at
com.ibm.ws.sib.processor.impl.mediation.MediationStateMachine.
tellMediationToStop(MediationStateMachine.java:1298)

The messaging engine hosting the mediation needs to be
restarted in order to resolve the issue.

Local fix

Restarting the server , which will re-start the messaging engine
will resolve the problem.

*                      application is installed/uninstalled.   *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The code controlling mediations did not expect the mediated
destination to be on an MQServer.  As a result, when a BUS
configuration reload occurs, and the mediation must be
stopped, the ClassCastException occurs, and the mediation
stops functioning.

Problem conclusion

PK94588 resolves the problem and mediations on MQServer
destinations can be stopped and started when a BUS
configuration reload occurs.

APAR PK94588 is currently targeted for inclusion in Service
Level (Fix Pack) 6.1.0.29 of WebSphere Application Server V6.1.
