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 WebSphere MQ.
Before you begin
Before you start you have to know the bus name, messaging engine name, WebSphere 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 WebSphere MQ link, you can avoid restarting the
application server more than once by following the steps given in Deleting a WebSphere 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 WebSphere MQ network are
synchronized once the deletions have taken place:
- Delete the topic mapping (see below).
- 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
- In the navigation pane, click
- Select the check box next to the topic mapping you want to delete.
- Click Delete.
- 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.
