Error description
A REFRESH CLUSTER(clusname) REPOS(NO) command was issued. Afterward, some other queue managers in the cluster were unreachable from the queue manager where the REFRESH was done. Applications received MQRC 2087 when attempting to send reply messages back to these queue managers. The issue occurs when a cluster sender channel is active at the time that the refresh is issued but then goes inactive before the full repository has republished that cluster-sender record in response to the refresh. Additional Symptom(s) Search Keyword(s): MQRC_UNKNOWN_REMOTE_Q_MGR CLUSSDR
Local fix
Do another REFRESH CLUSTER command or simply alter the description of the CLUSRCVR channel on the target queue manager to cause the cluster subscription to be republished.
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM MQ for z/OS Version 9 * * Release 1 Modification 0 * **************************************************************** * PROBLEM DESCRIPTION: A Partial Repository Queue Manager may * * incorrectly lose sight of other Qmgrs * * in a cluster, after a REFRESH CLUSTER * * REPOS(NO) command is issued. * **************************************************************** If auto-defined cluster sender channels are running when a REFRESH CLUSTER REPOS(NO) command is issued, but the channel stops prior to the REFRESH command processing completes, the republish of cluster Qmgr records may not be correctly added to the local cluster cache by reconcile processing. As a result the Qmgr may lose sight of the remote cluster Qmgr until the internal subscription for the Qmgr expires or the remote Qmgr's cluster receive definition is altered.
Problem conclusion
Cluster refresh and reconcile processing has been corrected, to ensure the republished cluster Qmgr record is added to the cluster cache, when a running cluster channel stops prior to refresh processing completing.
