We can delete topic space mappings so that subscribers on the local topic space cannot receive messages that are published in the foreign topic space. To delete topic space mappings, use the dmgr 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. A list of topic space map entries is displayed.
- Select the topic space map entry to remove.
- Click Delete.
- Save your changes to the master configuration.
