Create topic space mappings
A topic space mapping allows subscribers on the local topic space to receive messages published in the foreign topic space. We can create topic space mappings between two service integration buses.
We can create topic space mappings as part of the procedure to create a foreign bus connection, or we can create them separately, as described in this topic.
Note that for publishing and subscribing between a service integration bus and a foreign bus that represents a WebSphere MQ network, define topic mappings on the broker profile associated with the WebSphere MQ link.
To map a topic space on a local service integration bus to a topic space on a foreign service integration bus, use the console to complete the following steps.
- In the navigation pane, click Service integration -> Buses. A list of service integration buses is displayed.
- In the Buses pane, click the service integration bus that is connected to another bus, that is, the local bus you require.
- In the content pane, under Topology, click Foreign bus connections. A list of buses that have a foreign bus connection from the local bus is displayed.
- Select the required foreign bus.
- In the content pane, under Additional properties, click Service integration bus link routing properties.
- In the content pane, under Additional properties, click Topic space map entries.
- Click New.
- Specify the mappings as follows:
- Local topic space
- The name of the topic space on this (local) bus that is mapped to the remote topic space on the foreign bus.
- Remote topic space
- The name of the topic space on the foreign bus that is mapped to the local topic space.
The names of the local and foreign topic space do not have to match, but the names of the topics must match in both local and foreign buses.
- Click OK.
- Save the changes to the master configuration.
Results
The remote topic space is mapped to the local topic space.
