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 need 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.
Once you have deleted
the topic mapping you will need to restart the application server to allow
the changes to take effect.
Note: - If you intend to delete all topic mappings prior to 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 publish/subscribe broker profile.
- Deleting a topic mapping is a two-stage operation to ensure both the WebSphere Application Server and the message
brokers in the WebSphere MQ network are synchronized once the deletions have
taken place:
- Delete the topic mapping (see below).
- Restart the application server.
