This describes how you define topic mappings on the broker
profile, part of the publish/subscribe bridge on the WebSphere® MQ link.
Before you begin
Before you start you need to know the bus name, messaging
engine name, WebSphere MQ
link name and the name of the broker profile on which you intend to
define the topic mappings.
Note:
- Publication messages forwarded to a message broker in the WebSphere MQ network will
be republished on the same topic as they were originally published
to the service integration bus topic space, and vice versa.
- Once you have defined the topic mappings you will need to restart
the application server in order for the topic mappings to take effect.
About this task
To define topic mappings, use the administrative console
to complete the following steps. This task contains an optional step
to name the topic space and define the direction.
Procedure
- In the navigation pane, click bus_name link_name profile_name
- In the content pane, click New.
- Type the topic name. The topic name can contain
wild cards which must be in the service integration bus syntax. To
read about wild cards see Wild cards in topic mapping.
- In the topic space list, click the
name of the topic space that contains the topic. If you
don't select a name the default is used.
- Select the direction. The
direction of publication flow can be:
- Bi-directional
- Bidirectional publication flow which is simultaneous flow in both
directions on the (same) topic.
- To WebSphere MQ
