Question & Answer
Question
In the error log of one of my Partial Repository queue managers, the following error is reported:
AMQ9428E: Unexpected publication of a cluster queue object received ...
AMQ9428E: Unexpected publication of a cluster queue object received ...
.
I want to know what caused the error.
Cause
One possible cause is that in one of the Full Repository queue managers of the cluster, a Cluster-Sender (ClusSdr) channel was manually defined to this Partial Repository queue manager. As MQ cluster publications will be sent through the manual defined ClusSdr channel on the Full Repository queue manager, then the Partial Repostory queue manager will receive the publication which should be sent to Full Repository queue manager unexpectedly and it will throw AMQ9428E under this circumstance.
Answer
The proposed solution to solve the AMQ9428E error is to stop and delete, on the Full repository queue manager, the manually defined Cluster-Sender channel pointing to the Partial Repository queue manager, and then issue the start channel command so that the cluster can use the automatic channels again.
