Applications written in the Java programming language running under IBM WebSphere Application Server can use the Java Messaging Service (JMS) specification to perform messaging. Point-to-point messaging in this environment is provided by a WebSphere MQ for z/OS queue manager. Two classes of configuration are available:
Here, the queue manager providing the point-to-point messaging runs the WebSphere MQ for z/OS base function code provided with IBM WebSphere Application Server. This environment is suited to simple messaging between JMS applications running in the IBM WebSphere Application Server environment.
Here, the queue manager providing the point-to-point messaging runs WebSphere MQ for z/OS full function code installed as a separate product from IBM WebSphere Application Server for z/OS. In this environment, JMS applications running in the IBM WebSphere Application Server can participate fully in the functionality of a WebSphere MQ for z/OS network. For example, they can make use of the IMS Bridge, or exchange messages with WebSphere MQ for z/OS queue managers running on other platforms.
The information for WebSphere MQ for z/OS is supplied as a number of books, in PDF format. These books describe the full function form of WebSphere MQ for z/OS, but also identify the features, commands, API verbs, and so on, that are unavailable or restricted in the reduced function form. The WebSphere MQ for z/OS Library Web site describes the documentation available.
