Error description
WebSphere MQ V6 or V7 queues become "missing" from clusters. Application calls to MQOPEN (sometimes MQPUT1, MQPUT) suffer queue name lookup errors (Examples: 2085, 2082) when they try to access the affected cluster queues.
Local fix
Do not issue a REFRESH CLUSTER against a full repository queue manager.
Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 1 Modification 0 * **************************************************************** * PROBLEM DESCRIPTION: Message CSQX456I issued for a cluster * * queue which has no subscriptions. Also * * CSQX053E issued indicating an FFST * * for the missing subscription. * * The cluster queue indicated may * * disappear unexpectedly. * **************************************************************** * RECOMMENDATION: * **************************************************************** When a full repository is demoted to a partial it requests that any partial repositories in the cluster remake their subscriptions to another full repository. However it remakes the subscription with the REFRESH bit off, regardless of whether existing subscriptions had the REFRESH bit on. This can result in the situation where the cluster queue has its REFRESH bit on, but its subscriptions have the REFRESH bit off. In time this new subscription will expire and not be remade, even though the queue might be in constant use. When this happens the CSQX456I message and an FFST will be issued to indicate the missing subscription.
Problem conclusion
rrmRemakeSub will now initialise the new subscription with the correct values. 100Y CMQXRMNT CSQXRRMF
