APAR status
Closed as program error.
Error description
Messages are not going to the backout queue after the backout threshold is reached. The IBM MQ classes for JMS appears to be receiving the error MQRC 2097 (MQRC_CONTEXT_HANDLE_ERROR) - It cannot put the message onto the backout queue nor the dead letter queue. Instead the message is just rolled back again. This occurs when durable JMS Subscriptions are used.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: Users of MQ Classes for JMS, with Asynchronous message consumers, connecting to a topic with a backout threshold defined. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: Messages are not going to the backout queue after the backout threshold is reached. The IBM MQ classes for JMS appears to be receiving the error MQRC 2097 (MQRC_CONTEXT_HANDLE_ERROR) - It cannot put the message onto the backout queue nor the dead letter queue. Instead the message is just rolled back again. An FFST/FFDC is typically generated when encountering this behaviour, detailing reason code 2097.
Problem conclusion
Context is now set correctly for an Asynchronous message consumer when initialised for a topic/subscription. This enables the message to be successfully moved to a defined backout queue. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.1 LTS 9.1.0.12 v9.2 LTS 9.2.0.7 v9.3 LTS 9.3.0.1 v9.x CD 9.3.1 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 ---------------------------------------------------------------
