Modifying a WebSphere MQ server definition

You use a WebSphere® MQ server to configure a direct (single bus) connection to a WebSphere MQ for z/OS® queue manager or queue sharing group. This topic describes how to modify a WebSphere MQ server's connection and quality of service properties.

Before you begin

You can modify a WebSphere MQ server definition through the administrative console as described in this task, or you can modify a WebSphere MQ server definition using the wsadmin tool.

About this task

Modifying a WebSphere MQ server definition does not affect any configuration values previously inherited from WebSphere MQ servers by existing bus members. For example, if you create a WebSphere MQ server with the port number 1234, then add the server to a bus using that server's port number, then modify the WebSphere MQ server's port number to 2345, the bus member you previously created is not affected and still has the port number 1234.

Procedure

  1. Start the administrative console.
  2. Navigate to Servers > WebSphere MQ servers > [Content Pane] 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 you create a new WebSphere MQ server. It is not displayed on the administrative console panel that you use to create a new WebSphere MQ server, it is only displayed on the settings panel for an existing WebSphere MQ server.
    Use bindings transport mode if available
    The bus uses the WebSphere Application Server MQ_INSTALL_ROOT environment variable to find WebSphere MQ. If you want to use a direct binding to WebSphere MQ, rather than a TCP/IP network connection, select this option and configure the MQ_INSTALL_ROOT variable as described in Installing WebSphere MQ to interoperate with WebSphere Application Server.
    If you are using Resource Access Control Facility (RACF®) as the security manager on your WebSphere MQ for z/OS system, and using bindings transport mode, you must specify in uppercase characters the user names and passwords for authentication aliases. If you are using RACF and client transport mode, you can specify the user names and passwords in either upper or lower case characters.
    Test connection
    After you have modified the Connection properties, click this button to test the connection to WebSphere MQ.
    Trust user identifiers received in messages
    Select this option if you do not want the user identifiers in messages to be overwritten with the administrative name of the WebSphere MQ server.
  4. Click OK to confirm.
  5. Save your changes to the master configuration.
  6. Restart the application server.
