Resolving a partitioned (split brain) problem in DR RDQM

A partitioned problem can occur if both queue managers in a disaster recovery pair run in the primary role at the same time.

About this task

If you promoted the secondary instance of a queue manager on the recovery node while the original primary instance continued to run on the main node, then you effectively have two versions of the same queue manager running, each with their own view of the queue manager data. The DR status for the queue manager on each node is reported as Partitioned.

You must decide which of the two queue managers has the most correct view of the data, and retain that set while discarding the other. You use the rdqmdr command to complete this operation.
