A WebSphere® MQ server represents a WebSphere MQ queue manager or (for WebSphere MQ for z/OS®) queue-sharing group. You cannot delete a WebSphere MQ server bus definition directly. Instead, when you delete a specified WebSphere MQ server, you remove any associated WebSphere MQ server bus members, as well as assigned queue points and mediation points.
Decide which method to use to configure these resources. You can delete a WebSphere MQ server by using the administrative console as described in Deleting a WebSphere MQ server definition, or by using the deleteSIBWMQServer command.
Deleting a WebSphere MQ server definition does not affect the associated queue managers, queue-sharing groups, queues or messages on your WebSphere MQ network.
