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
- From WebSphere Application Server to a message broker in the WebSphere
MQ network.
- From WebSphere MQ
- From a message broker in the WebSphere MQ network to WebSphere Application
Server.
- In the broker stream queue list, click the
name of the broker stream queue you want to use. If the queue you require
is not on the list, click other, please specify and
enter the name of the broker stream queue. The broker stream queue
is the queue in the WebSphere MQ network to which the message broker is connected
and which is used as the input node for a message flow containing a publication
node.
- In the subscription point list, click the
WebSphere MQ message broker subscription point you want to use. If the subscription
point you require is not on the list, click other, please specify and
enter the name of the subscription point. The default subscription
point is used if no value is specified.
- Click OK.
- Save your changes to the master configuration.
