Error description
IBM MQ generates large FDCs with Probe Id RM191020 for the repository manager process (amqrrmfa) The FDCs are generated along with the reported AMQ9469 error message in the queue manager logs. They contain a full dump of the entire cached queue manager cluster configuration and can be numerous. As a result they can consume large amounts of disk space. Examples: AMQ9469: Update not received for CLUSRCVR channel TO.QM1 hosted on queue manager QM1_2016-01-01_11.11.11 in cluster CLUSTER1. EXPLANATION: The repository manager detected that the CLUSRCVR channel has not been re-published by its owning queue manager. This re-publish action should have happened automatically 4 days ago, or in the time between then and now. See the knowledge center for the full error message: http://www.ibm.com/support/knowledgecenter/en/SSFKSJ_8.0.0/com.i bm.mq.ref.doc/amq9.htm The FDC will show the following: Probe Id :- RM191020 Component :- rrmMaintainClqMgr Program Name :- amqrrmfa Thread :- 1 Repository Probe Type :- INCORROUT Probe Description :- AMQ6125: An internal WebSphere MQ error has occurred. Comment1 :- Repeated occurrences of AMQ9469 MQM Function Stack amqrrfma_main rrmMain rrmRepository rrmGetMsg rrmRunTimers rrmMaintenance rfxEnumCLQMGR rrmMaintainClqMgr xcsFFST
Local fix
The following environment variables can be exported to reduce the size of the FDCs being generated. The queue manager will need to be restarted after they are in place. . Unix: export AMQ_RRMFA_MSG_HISTORY=0 export AMQ_RRMFA_SUPPRESS_CACHEDUMP=1 Windows: set AMQ_RRMFA_MSG_HISTORY=0 set AMQ_RRMFA_SUPPRESS_CACHEDUMP=1 .
Problem summary
**************************************************************** * USERS AFFECTED: * * All users of IBM MQ for z/OS Version 9 Release 0 * * Modification 0 * **************************************************************** * PROBLEM DESCRIPTION: * * When CSQX469E messages are put out repeatedly, FFSTs are * * produced. These are shown with a CSQX053E message being * * produced, and the FFST information being written to * * CSQXSNAP. * **************************************************************** * RECOMMENDATION: * * N/A * **************************************************************** Message CSQX469E is produced when a CLUSRCVR channel has not been republished to the full repositories within a cluster. However, if this message is still being produced, such as in the cases it is known and expected, FFSTs will be issued 30 days into the grace period. The FFST written to CSQXSNAP will contain 'Repeated CSQX469E'.
Problem conclusion
The FFSTs in this case have been removed, and will no longer be produced for this scenario.
