Defining topic mappings

This describes how you define topic mappings on the broker profile, part of the publish/subscribe bridge on the WebSphere MQ link.

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:
  1. 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.
  2. Once you have defined the topic mappings you will need to restart the application server in order for the topic mappings to take effect.
To define topic mappings, use the administrative console to complete the following steps. This task contains optional steps to name the topic space and define the direction.
  1. In the navigation pane, click Service integration > Buses > [Content Pane] bus_name > [Topology] Messaging engines > [Content Pane] engine_name > [Additional Properties] WebSphere MQ links > [Content Pane] link_name > [Additional Properties] Publish/subscribe broker profiles > [Content Pane] profile_name > [Additional Properties] Topic mappings
  2. In the content pane, click New.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
  8. Click OK.
  9. Save your changes to the master configuration.
