Closed as program error.
Error description
runmqdlq fails to process a message from SYSTEM.PROTECTION.ERROR.QUEUE using a rule which has full name of the queue in DESTQ attribute of dlq rule. for example: REASON(MQRC_SECURITY_ERROR) DESTQ(MY.LOCAL.QUEUE) + ACTION(FWD) FWDQ(QL1) FWDQM(QM1) HEADER(NO)
Local fix
To be able to retrieve a message matching the rule, use a wildcard in DESTQ keyword. Ie: DESTQ(MY.LOCAL.QUEUE*) or DESTQ(MY.LOCAL.*)
Problem summary
**************************************************************** USERS AFFECTED: Users using the runmqdql dead letter queue handler against the MQ AMS SYSTEM.PROTECTION.ERROR.QUEUE, with a rule that specified a DESTQ value with a specific queue name. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: Messages put to the SYSTEM.PROTECTION.ERROR.QUEUE incorrectly provided the destination queue name in the dead letter header (MQDLH) as null-terminated, instead of space-padded as defined by the MQDLH specification. This caused runmqdlq DESTQ pattern matching to fail if a complete queue name was specified for the DESTQ in the match rule
Problem conclusion
The MQ AMS code has been modified to ensure the destination queue name in the dead letter header is space padded when a message is put to the SYSTEM.PROTECTION.ERROR.QUEUE. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.0 LTS 9.0.0.11 v9.1 CD TBC. v9.1 LTS 9.1.0.7 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 ---------------------------------------------------------------
