APAR status
Closed as program error.
Error description
A REFRESH CLUSTER(clusname) REPOS(NO) command was issued. Afterwards, some other queue managers in the cluster were unreachable from the queue manager where the REFRESH was done. Applications received MQRC 2085 or 2087 when attempting to send messages 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 republished channel information from the Full Repositories has been received and processed.
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: Users who run REFRESH CLUSTER while channels are running. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: If auto-defined cluster sender channels were running when a REFRESH CLUSTER command was issued, and the channel stopped prior to the completed handshake with the Full Repositories, the refreshed records for those channels might not have been correctly added to the local cluster cache when they were received from the Full Repositories and processed.
Problem conclusion
Cluster refresh and reconcile processing has been corrected, to ensure the republished cluster Qmgr record is added to the cluster cache, in the scenario described. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.14 v9.0 LTS 9.0.0.8 v9.1 CD 9.1.4 v9.1 LTS 9.1.0.4 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 ---------------------------------------------------------------
