Configure foreign bus connections

We can configure a bus to connect to, and exchange messages with, other messaging networks. To do this, 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. 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 WebSphere 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 we 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)

To ensure that dynamic configuration updates are made to each node, click System administration -> Console Preferences to display the Console Preferences window, then select Synchronize changes with nodes.
