Before you stop an MQ queue manager, issue a stop administration message to all the MQ queue-manager-proxy bridge objects. This stops the MQe network from trying to use the MQ queue manager and possibly interfering with the shutdown of the MQ queue manager. This can also be achieved by issuing a single stop administration message to the MQeBridges object.
If you choose not to stop the MQ queue-manager-proxy bridge object before you shut the MQ queue manager, the behavior of the MQ shutdown and the MQ bridge depends on the type of MQ queue manager shutdown you choose, immediate shutdown or controlled shutdown.
