Modify a WebSphere MQ server definition

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. We can modify a WebSphere MQ server using the console as described in this task, or 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, we do not change any configuration values previously inherited from this WebSphere MQ server by existing bus members. For example, suppose we create a WebSphere MQ server with the port number 1234, then add the server to a bus and specify that server port number. If we 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.

1. Start the console.

2. Navigate to Servers -> Server Types -> WebSphere MQ servers -> server_name. The WebSphere MQ server [Settings] form is displayed.

3. Make modifications as required.

   For more information, refer to the WebSphere MQ server [Settings] form and the following notes:

   UUID

   This identifier is assigned automatically when creating a new WebSphere MQ server definition.

   Use bindings transport mode if available

   To connect to a WebSphere MQ queue manager or queue-sharing group in bindings mode, WebSphere Application Server needs to know where to load native libraries from. This information is stored in the Native library path property of the WebSphere MQ messaging provider. To use a direct binding to WebSphere MQ, rather than a TCP/IP network connection, select this option and configure the Native library path property as described in Configure the WebSphere MQ messaging provider with native libraries information.

   If we are using Resource Access Control Facility (RACF ) as the security manager on the WebSphere MQ for z/OS system, and using bindings transport mode, specify in uppercase characters the user names and passwords for authentication aliases. If we are using RACF and client transport mode, we can specify the user names and passwords in either upper or lowercase characters.

   Test connection

   After we have configured the Connection properties, click this button to test the connection to WebSphere MQ.

   Trust user identifiers received in messages

   Select this option if we do not want the user IDs in messages to be overwritten with the administrative name of the WebSphere MQ server.

4. Click OK to confirm.

5. Save the changes to the master configuration.
   

6. Restart the application server.
