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 attached to a service integration bus, and vice versa.
A construct called an WebSphere MQ link connects a 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 as shown in Figure 1 and Figure 2. A messaging engine can contain multiple WebSphere MQ links
