What WebSphere MQ product is required if you are running WebSphere Application Server for z/OS and want to use JMS?
 Flash (Alert)
 
Abstract
You are required to have only the REDUCED FUNCTION form of WebSphere® MQ that is shipped with WebSphere® Application Server for z/OS®, if using Java Messaging Service (JMS). This is also known as the Integral JMS provider (IJP), or Embedded WebSphere JMS provider (embedded messaging).
 
Content
Applications written in Java™ programming language running under WebSphere Application Server can use the 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:
  1. REDUCED FUNCTION for WebSphere MQ for z/OS
    The WebSphere MQ for z/OS base function code provided with WebSphere Application Server for z/OS enables point-to-point messaging through the queue manager. This environment is suited to simple messaging between JMS applications running in WebSphere Application Server for z/OS environment. This is also known as the Integral JMS provider (IJP) or Embedded WebSphere JMS provider (embedded messaging).

  2. FULL FUNCTION for Websphere MQ for z/OS
    The WebSphere MQ for z/OS full function code is installed as a separate product from WebSphere Application Server for z/OS product. It allows point-to-point messaging through the queue manager. In this environment, JMS-enabled WebSphere Application Server applications 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.


Note:
The Internet Gateway feature is available only as part of the IBM WebSphere MQ Version 5 product; it is not part of the reduced-function WebSphere MQ that is included with WebSphere Application Server Version 5. If you are installing the two products together, use the IBM WebSphere MQ program directory to install the WebSphere MQ FMIDs, and the WebSphere Application Server program directory to install the WebSphere Application Server for z/OS (and optional Java) FMIDs. The instructions in the WebSphere Application Server for z/OS program directory cannot be used to install the separate WebSphere MQ product.

The WebSphere Application Server for z/OS program directory has a note in section 5.3, "Installing WebSphere for MQ," stating that the MQ installation steps in the WebSphere Application Server for z/OS program directory can be skipped if you already have a full version of WebSphere MQ Version 5.3.1 installed. This also applies if the two products are being installed at the same time.
