Use WebSphere MQ links to connect a bus to a WebSphere MQ network

If you operate within a WebSphere Application Server environment, sending messages across a service integration bus, we 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. We can configure a WebSphere MQ link using the dmgr console as described in this task, or we can configure a WebSphere MQ link using wsadmin. 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.

Using the WebSphere MQ link panels of the WAS administration console, we can choose:

• The WebSphere MQ queue manager or queue-sharing group in the WebSphere MQ network through which your messages will flow
• Whether to enable WAS applications to publish and subscribe to a message broker in the WebSphere MQ network

• Learn about interoperating with a WebSphere MQ network.
• Create a new WebSphere MQ link.
• Administer an existing WebSphere MQ link.
• Create applications that can interoperate with WebSphere MQ.

Subtopics

• Create a new WebSphere MQ link
  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. Use the foreign bus connection wizard to create a foreign bus and link it to the WebSphere MQ network through a WebSphere MQ link.
• Administer an existing WebSphere MQ link
  The WebSphere MQ link enables the exchange of point-to-point and publish/subscribe messages with a WebSphere MQ network. After we have created a WebSphere MQ link we can undertake various administrative actions on the link.
