An enterprise service bus with links to WebSphere MQ networks

Service integration buses can contain links to WebSphere MQ networks. This allows applications connected to a WebSphere MQ queue manager to send messages to an application that is attached to a service integration bus, and for such an application to send messages to WebSphere MQ.

When a service integration bus is connected to a WebSphere MQ network, the network is extended by adding support for:

The WebSphere MQ network is represented by a foreign bus configured on a messaging engine. A construct called an WebSphere MQ link connects the messaging engine to an MQ queue manager using sender and receiver channels, thereby providing a bridge between the bus and the so-called gateway queue manager of a WebSphere MQ network.

The WebSphere MQ link provides connectivity not just with the messaging engine that hosts the link, but also with the other messaging engines in the bus. All the messaging engines in the bus appear to the WebSphere MQ network as if they were a single queue manager (they inherit the queue manager name from the WebSphere MQ link)

WebSphere MQ links can be used in a number of different configurations. A messaging engine can contain multiple WebSphere MQ links to different gateway queue managers.

Links to WebSphere MQ networks are implemented by the service integration technologies of WebSphere Application Server. .
