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.
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
- Start the administrative console.
- Navigate to The WebSphere MQ server [Settings] form
is displayed.
- 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.
- Click OK to confirm.
- Save your changes to the master configuration.
- Restart the application server.
