Closed as program error.
Error description
If the user sets the queue manager's DEFXMITQ attribute to SYSTEM.CLUSTER.TRANSMIT.QUEUE, then messages can be placed on that transmission queue with invalid CorrelId values and therefore these messages will never be acted upon by any CLUSSDR channel, and will remain on the SYSTEM.CLUSTER.TRANSMIT.QUEUE forever. In APAR IV01112 additional checks were added to the queue manager command processing routines (example: runmqsc) to disallow setting the value "SYSTEM.CLUSTER.TRANSMIT.QUEUE" for the DEFXMITQ attribute for the queue manager object, and write an error message. There is an additional way to set a value for DEFXMITQ, which is to supply the -d switch on the crtmqm command. A similar validity check was not applied to crtmqm under IV01112. A validity check must be added to crtmqm to make it consistent with the other ways of setting DEFXMITQ.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: Users who mistakenly try to set the DEFXMITQ attribute for the queue manager object to the value SYSTEM.CLUSTER.TRANSMIT.QUEUE. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: It is not valid to set the DEFXMITQ for the queue manager to the value SYSTEM.CLUSTER.TRANSMIT.QUEUE, but the WebSphere MQ product code was allowing this value to be set via the crtmqm -d switch.
Problem conclusion
Additional checks have been added to the WebSphere MQ product during crtmqm to disallow setting the value "SYSTEM.CLUSTER.TRANSMIT.QUEUE" for the DEFXMITQ attribute for the queue manager object. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v7.5 7.5.0.5 v8.0 8.0.0.1 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 ---------------------------------------------------------------
