Error description
When altering cluster queue from PUT(DISABLED) to PUT(ENABLED) at Full Repository QMGR, the update is not propagated to Partial Repository QMGR (AMQ9428 mismatch subscription is issued by Partial Repositoy QMGR), becuase Full Repository send cluster command to Partial Repository with old Subscription ID. This is because Subscription is replaced by old one incorrectly on Full Repository QMGR.

Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM MQ for z/OS Version 9 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: Changes to a cluster object are not * * correctly propagated to a partial * * repository that is connected to a full * * repository by multiple channels * * following a REFRESH CLUSTER command. * **************************************************************** A partial repository (PR) remade the subscriptions for a cluster queue it had accessed, however the PCF command message was delayed reaching the full repository (FR). At the same time REFRESH CLUSTER was issued on the PR, and the command messages associated with the refresh arrived at the FR using a different channel, and the subscription for the queue was deleted. When the PR accessed the queue again, a new subscription was created, however when the delayed PCF message subsequently arrived it caused the new subscription to be replaced by the old subscription. This resulted in the PR rejecting updates to the queue as reported by error AMQ9428 (if the PR runs on distributed platforms) or CSQX428E (if the PR runs on z/OS).
Problem conclusion
rrmQueryObject is changed to correctly determine the newer subscription, and to prevent it replacing the new subscription with an older subscription for the object.
Temporary fix
