Configuring foreign bus connections
You can configure a bus to connect to, and exchange messages with, other messaging networks. To do this, you must configure a foreign bus connection. A foreign bus connection encapsulates information related to the remote messaging network, such as the type of the foreign bus and whether messaging applications are allowed to send messages to the foreign bus.
About this task
You can only send messages to the foreign bus. You cannot receive messages from the foreign bus.
A foreign bus connection is associated with a service integration bus. The bus with which the foreign bus connection is associated is known as the local bus. The foreign bus connection represents another service integration bus, either in the same cell as the local bus or in a different cell, or it represents a IBM MQ queue manager. From the local bus, every other bus is regarded as a foreign bus, even if it is a bus in the same cell.
Messages route to a foreign bus either directly through a link between the local bus and the foreign bus, or indirectly through one or more intermediate buses.
If, when you configure the local bus, you select Configuration reload enabled, future changes to the configuration information for any foreign bus connections are updated automatically. The time when these changes take effect varies:
- Foreign Bus Connection properties
- Immediately
- WebSphere® MQ link properties
- On channel restart, except Description (immediately), and Initial State (on messaging engine restart)
- MQ sender channel properties
- On channel restart, except Initial State (on messaging engine restart or sender channel creation)
- MQ receiver channel properties
- On channel restart, except Initial State (on messaging engine restart or receiver channel creation)
- Publish/subscribe broker profile (0 to n) properties
- Immediately
- Service integration bus link properties
- On link restart, except Description (immediately), and Initial State (on messaging engine restart or link creation)
