Error description
After a WebSphere MQ queue manager failure, the WebSphere Application Server Servant Region listener port failed to restart due to MQRC=2009, MQRC_CONNECTION_BROKEN' was returned from WMQ. The JMS traces show that the connection was not being obtained from the connection pool, but was being created as a new managed connection for which a new binding connection to the queue manager was attempted to be created. The trace showed that the MQCONNX was successful but the MQOPEN was failing in the native bindings code of WMQ. From a WMQ queue manager perspective the MQOPEN was failing with MQRC 2009 as the JMS code was using an 'old' context.
Local fix
The workaround would be to reduce the reconnection interval on the listener port to 30 seconds which will allow the listener port to reconnect in 60 seconds if this problem occurs.

**************************************************************** USERS AFFECTED: Users of the WebSphere MQ v7 Resource Adapter within the WebSphere Application Server on the zOS platform, that are making use of the internal processing change that was delivered under APAR PM41841 that has been turned on under the direction of IBM support. Platforms affected: All Distributed (iSeries, all Unix and Windows) +Java +Java zOS **************************************************************** PROBLEM SUMMARY: When making use of the internal processing change provided under APAR PM41841 a problem was found where the context remained present when a new connection was established to the zOS Queue Manager when that context is now invalid.
Problem conclusion
This APAR fixes the problem by making sure that the context object is not invalid when a new connection is made to the zOS queue manager after a failure in the zOS queue manager. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v7.0 Platform Fix Pack 7.0.1.11 -------- -------------------- Windows 7.0.1.11 AIX 7.0.1.11 HP-UX (PA-RISC) 7.0.1.11 HP-UX (Itanium) 7.0.1.11 Solaris (SPARC) 7.0.1.11 Solaris (x86-64) 7.0.1.11 iSeries 7.0.1.11 Linux (x86) 7.0.1.11 Linux (x86-64) 7.0.1.11 Linux (zSeries) 7.0.1.11 Linux (Power) 7.0.1.11 zOS 7.0.1.11 v7.1 Platform Fix Pack 7.1.0.3 -------- -------------------- Windows 7.1.0.3 AIX 7.1.0.3 HP-UX (Itanium) 7.1.0.3 Solaris (SPARC) 7.1.0.3 Solaris (x86-64) 7.1.0.3 iSeries 7.1.0.3 Linux (x86) 7.1.0.3 Linux (x86-64) 7.1.0.3 Linux (zSeries) 7.1.0.3 Linux (Power) 7.1.0.3 zOS 7.1.0.3 Platform v7.5 -------- -------------------- Multiplatforms 7.5.0.1 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 ---------------------------------------------------------------
