Connecting buses directly

Use this task to connect two service integration buses together.

The buses must exist, and each bus must have at least one bus member before you can connect them. The buses can be in the same cell, or in different cells.
Note: The buses that you connect must have unique names. If the buses have the same name, the connection will fail.
To connect two separate bus configurations so that messages can be exchanged between them:
  1. In the first bus create a foreign bus, using a direct routing definition type, to represent the second bus, see Adding a foreign bus.
  2. In the second bus create a foreign bus, again using a direct routing definition type, to represent the first bus.
  3. In the first bus:
    1. Optional: Create a topic space mapping, see Creating topic space mappings You need only create a topic space mapping if you need to connect topic spaces. See Configuring topic space mappings between service integration buses
    2. Configure destination defaults, unless a foreign destination will be created explicitly. See Configuring destination defaults for a foreign bus
  4. In the first bus, create a service integration bus link from the messaging engine that is to host the link to the second (foreign) bus. See Adding a service integration bus link. This associates the messaging engine with the virtual link.
  5. In the second bus, create a service integration bus link from the messaging engine that is to host the link to the first (foreign) bus. The name of the service integration bus link must match the name of the service integration bus link that you created in the first bus. This associates the messaging engine with the virtual link.
  6. Restart the messaging engine in the first bus (restart the server that contains the messaging engine). The service integration bus link is started when the messaging engine is started, as long as its Initial state is configured as started.
  7. Restart the messaging engine in the second bus (restart the server that contains the messaging engine).
The two buses are now connected and they can exchange messages. When you create default messaging resources, configure the connection factory to connect to the local bus, and configure the destination to connect to the foreign bus.
