APAR status
Closed as program error.
Error description
MQ 7.0 JMS clients affected by APAR IV36766 send a request to a queue manager which causes FFSTs to be issued and the connection to be closed.
Local fix
Upgrade JMS client to a supported level.
Problem summary
**************************************************************** USERS AFFECTED: Users connecting V7.0 JMS clients to an MQ 9.1 queue manager are potentially affected. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: A V7.0 JMS client connected to V9.1 queue manager and opened a queue object, a protocol error was detected by the queue manager leading to an AMQ9504 error being logged, a probe RM680037 FFST and the connection was ended. The JMS client reported a JMSException with RC=2009 (MQRC_CONNECTION_BROKEN).
Problem conclusion
APAR IV36766 originally identified a problem where the V7.0 JMS client supplied an invalid protocol flow to open an object on the queue manager. Whilst this issue was identified and fixed in the JMS client, this older JMS level is still prevalent, particularly from older resource adapters bundled in WebSphere Application Server. This APAR changes the queue manager to safely tolerate and respond using the shorter request flows. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.1 CD TBC. v9.1 LTS 9.1.0.5 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
