Manage a messaging engine in a cluster

During run time, you can stop or start a messaging engine in a WAS cluster, independently of the server in which it is running.

You might want to stop and restart a messaging engine in this way if, for example, to take a backup copy.

A stop or start action of a messaging engine applies to the server on which it is performed and is a runtime alteration of the state of the messaging engine. It does not alter the configured "Initial state" of the messaging engine.

If a failover occurs, the fact that we have stopped the messaging engine does not affect the behavior of the newly-activated instance; the messaging engine instance behaves in accordance with the configuration settings of the server in which it is activated.
