Moving from the embedded WebSphere JMS provider to WebSphere MQ

Use this task to move from the embedded WebSphere JMS provider to WebSphere MQ as the provider of messaging services and resources for WebSphere enterprise applications.

Why and when to perform this task

To move from the embedded WebSphere JMS provider to WebSphere MQ as the provider of messaging services and resources for WebSphere enterprise applications, you need to install and configure a supported level of WebSphere MQ with the required MQ features.

Existing JMS resource definitions for the embedded WebSphere JMS provider continue to work with WebSphere MQ as the JMS provider, so you do not need to redefine those JMS resources. However, to take advantage of the extra configuration options for WebSphere MQ, you can use the administrative console to define new JMS resources as WebSphere MQ resources; for example, to define MQ Queue Connection Factories.

Steps for this task

  1. For WebSphere MQ point-to-point messaging, install the base WebSphere MQ product.

    When installing WebSphere MQ, perform the following actions:

    1. When asked if you want to remove or modify the version of WebSphere MQ currently installed, choose to remove the Server. (The WebSphere MQ install program recognizes the installed WebSphere embedded messaging as an installed version of WebSphere MQ.)
    2. Select the option to keep existing queue managers.
    3. Proceed with the installation of the full WebSphere MQ Server by running the install program again, after the old WebSphere MQ server (the Embedded Messaging Server) has been removed.
    4. Do not install the WebSphere MQ Client. Use the WebSphere Application Server Embedded Messaging Client that was installed with WebSphere embedded messaging.

    For information about installing WebSphere MQ, or migrating to WebSphere MQ from an earlier release, see the appropriate WebSphere MQ Quick Beginnings book.

    You can get WebSphere MQ messaging platform-specific books at this Web page: Target can be accessed only when this topic is linked to the World Wide Web   http://www-306.ibm.com/software/integration/wmq/library/library6x.html

  2. Configure WebSphere MQ queue resources to IBM WebSphere Application Server.
    For point-to-point messaging WebSphere applications can continue to use WebSphere queue resources (through the embedded messaging JMS provider) or WebSphere MQ queue resources.d
  3. For WebSphere MQ publish/subscribe messaging, install a Publish/Subscribe broker, such as WebSphere MQ Event Broker. For publish/subscribe messaging, WebSphere applications can continue to use WebSphere topic resources (through the embedded messaging JMS provider).

    For more information about installing WebSphere Event Broker (formerly WebSphere MQ Event Broker) or WebSphere Message Broker (formerly WebSphere MQ Integrator), see the following Web sites:

  4. Configure WebSphere MQ topic resources to IBM WebSphere Application Server.
    For publish/subscribe messaging, WebSphere applications can continue to use WebSphere topic resources (through the embedded messaging JMS provider) or WebSphere MQ topics.
