Point-to-point messaging with a WebSphere MQ network

The WebSphere MQ link, defined on a messaging engine in the service integration bus, describes the attributes required to connect to, and send or receive messages to or from, a WebSphere MQ queue manager or (for WebSphere MQ for z/OS ) queue sharing group that acts as a gateway to the WebSphere MQ network.

Point-to-point messaging might be:

The following figure shows the flow of point-to-point messages across the WebSphere MQ link.

See Request-reply messaging through a WebSphere MQ link for more information about the reply messages transmitted across the WebSphere MQ link.

Point-to-point messaging might also include:

The following figure shows how messages can be exchanged between applications and messaging engines that are on the same bus, as well as between the WebSphere MQ link and queue managers connected to the gateway queue manager in the WebSphere MQ network.
