Error description
The WebSphere Application Server Listener Port property "maxMessages" allows multiple messages to be processed by the Listener Port in a single transaction. WebSphere MQ V7 classes for JMS do not honour that property in an XA environment so each message is processed in its own transaction and a commit occurs for every message.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: This issue affects users of the WebSphere MQ classes for Java, which are making use of XA Transactions with Listener Ports in WebSphere Application Server who are attempting to process multiple messages in a single transaction. Platforms affected: All Distributed (iSeries, all Unix and Windows) +Java +Java zOS **************************************************************** PROBLEM SUMMARY: The WebSphere Application Server Listener Port property "maxMessages" is not being honored by the WebSphere MQ V7 classes for JMS in an XA environment. This results in each message being processed in its own transaction despite the user specifying that multiple message should be processed in one transaction.
Problem conclusion
In order to have the Listener Port property "maxMessages" honored by the WebSphere MQ V7 classes for JMS a new Generic JVM Argument has been created: com.ibm.mq.jms.tuning.enableMaxMessagesForXAListenerPorts This argument takes as an argument a boolean value which represents whether the MaxMessages property is enabled. For example to enable this property: -Dcom.ibm.mq.jms.tuning.enableMaxMessagesForXAListenerPorts=true --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: v7.0 Platform Fix Pack 7.0.1.10 -------- -------------------- Windows U200352 AIX U853055 HP-UX (PA-RISC) U853082 HP-UX (Itanium) U853087 Solaris (SPARC) U853083 Solaris (x86-64) U853089 iSeries 7.0.1.10 Linux (x86) U853084 Linux (x86-64) U853088 Linux (zSeries) U853085 Linux (Power) U853086 zOS 7.0.1.10 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 ---------------------------------------------------------------
