If you operate within a WebSphere® Application Server environment, sending messages across a service integration bus, you can also exchange point-to-point and publish/subscribe messages with applications in a WebSphere MQ network. To do this, you configure a foreign bus connection that links to a WebSphere MQ network through a WebSphere MQ link.
Decide which method to use to configure these resources. You can configure a WebSphere MQ link by using the administrative console as described in this task, or you can configure a WebSphere MQ link by using the wsadmin tool.
A WebSphere MQ link provides a server to server channel connection between a service integration bus and a WebSphere MQ queue manager or queue-sharing group, which acts as the gateway to the WebSphere MQ network. The link operates on a messaging engine in a service integration bus to provide functions that simplify and automate interoperation with WebSphere MQ.
