A WebSphere® MQ server represents a WebSphere MQ queue manager or (for WebSphere MQ for z/OS®) queue-sharing group. This topic describes how to modify a WebSphere MQ server connection and quality of service properties.
Decide which method to use to configure these resources. You can modify a WebSphere MQ server by using the administrative console as described in this task, or by using the modifySIBWMQServer command.
A WebSphere MQ server definition defines the connection to an underlying WebSphere MQ queue manager or queue-sharing group and the associated queues.
When you modify a WebSphere MQ server definition, you do not change any configuration values previously inherited from this WebSphere MQ server by existing bus members. For example, suppose you create a WebSphere MQ server with the port number 1234, then add the server to a bus and specify that server port number. If you subsequently modify the WebSphere MQ server port number to 2345, the bus member you previously created is not affected and still has the port number 1234.
