Deleting a topic mapping on an IBM MQ link publish/subscribe broker profile

This describes how you delete a topic mapping on a broker profile on a WebSphere® MQ link, which forms part of a publish/subscribe bridge between WebSphere Application Server and IBM MQ.

Before you begin

Before you start you have to know the bus name, messaging engine name, IBM MQ link name and broker profile name on which you intend to delete the topic mapping.
Note:
  • If you intend to delete all topic mappings before deleting the broker profile or the IBM MQ link, you can avoid restarting the application server more than once by following the steps given in Deleting a IBM MQ link publish/subscribe broker profile.
  • Deleting a topic mapping is a two-stage operation to ensure both the WebSphere Application Server (base) and the message brokers in the IBM MQ network are synchronized once the deletions have taken place:
    1. Delete the topic mapping (see the following Procedure section).
    2. When you have deleted the topic mappings, the changes take effect immediately if you have enabled dynamic configuration updates, otherwise restart the application server.

About this task

To delete a topic mapping, use the administrative console to complete the following steps.

Procedure

  1. In the navigation pane, click Service integration -> Buses -> bus_name -> [Topology] Messaging engines -> engine_name -> [Additional properties] IBM MQ links -> link_name -> [Additional Properties] Publish/subscribe broker profiles -> profile_name -> [Additional Properties] Topic mappings
  2. Select the check box next to the topic mapping you want to delete.
  3. Click Delete.
  4. Save your changes to the master configuration.

What to do next

Any topic mappings that you have deleted are automatically cleaned up by the publish/subscribe bridge when the application server is restarted.
