Interoperating with a WebSphere MQ network

The default messaging provider (service integration) can interoperate with a WebSphere MQ network by using a WebSphere MQ link or a WebSphere MQ server. Alternatively, you can use WebSphere MQ as your messaging provider. Each type of connectivity is designed for different situations, and provides different advantages. Choose the most appropriate interoperation method for each of your messaging applications.

About this task

WebSphere Application Server can interoperate with WebSphere MQ in the following ways:

WebSphere MQ links provide a traditional WebSphere MQ-style solution to connecting resources. WebSphere MQ servers add the ability to directly access WebSphere MQ queues from within a bus.

Table 1. The different ways of interoperating with WebSphere MQ
No bus: The WebSphere MQ messaging provider Multi-bus: WebSphere MQ network as a foreign bus (using WebSphere MQ links) Single-bus: Queue manager as a bus member (a WebSphere MQ server)
A JMS application uses the default messaging provider to pass a message to the WebSphere MQ messaging provider, which uses JMS messaging protocols to pass the message to a WebSphere MQ queue or topic.
A JMS application uses the default messaging provider to pass a message to a service integration bus. The bus passes the message across a WebSphere MQ link to a WebSphere MQ queue or topic. Service integration views the WebSphere MQ system as if it were a foreign bus.
A JMS application uses the default messaging provider to pass a message to a service integration bus. The bus passes the message through a WebSphere MQ server to a WebSphere MQ queue. Service integration views the WebSphere MQ system as if it were a bus member.
The WebSphere MQ messaging provider does not use service integration. It provides JMS messaging access to WebSphere MQ directly from WebSphere Application Server. A WebSphere MQ link provides an indirect connection between a service integration bus and a queue manager within a WebSphere MQ messaging network. With this type of connection, the messaging bus is seen by the WebSphere MQ network as a virtual queue manager, and the WebSphere MQ network is seen by service integration as a messaging bus. A Websphere MQ link allows WebSphere Application Server applications to send point-to-point messages to WebSphere MQ queues (defined as destinations in the service integration bus), and allows WebSphere MQ applications to send point-to-point messages to destinations in the service integration bus (defined as remote queues in WebSphere MQ). The link also allows WebSphere Application Server applications to subscribe to messages published by WebSphere MQ applications, and WebSphere MQ applications to subscribe to messages published by WebSphere Application Server applications. The link converts messages between the formats used by WebSphere Application Server and those used by WebSphere MQ, and handles data conversion of messages. A WebSphere MQ server provides a direct connection between service integration messaging engines in WebSphere Application Server and queue managers or queue sharing groups in WebSphere MQ for z/OS. WebSphere MQ server is designed to exploit the high availability, and optimum load balancing characteristics provided by a WebSphere MQ for z/OS network. WebSphere MQ server defines the connection and quality of service properties used for the connection, and also ensures that messages are converted between the formats used by WebSphere Application Server, and those used by WebSphere MQ.
