Moving from the embedded WebSphere JMS provider to WebSphere MQ 6.x

Use this task to move from the embedded WebSphere JMS provider to WebSphere MQ 6.x 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. Uninstall the existing WebSphere MQ software (the Embedded Messaging Server and client) as follows:
    1. Stop WebSphere Application Server.
    2. Proceed with the uninstallation of the existing WebSphere MQ software. When asked if you want to remove or modify the version of WebSphere MQ currently installed, choose to remove the Server.
    3. Select the option to keep existing queue managers if applicable.
    4. Select the options to uninstall both WebSphere MQ Server and WebSphere MQ Client.
  2. For both WebSphere MQ point-to-point and WebSphere MQ publish/subscribe messaging, install the base WebSphere MQ product.
    1. Proceed with the installation of full WebSphere MQ Version 6 by running the install program after the old WebSphere MQ server and client (the Embedded Messaging Server and client) have been removed.
    2. Install the WebSphere MQ 6 Server and Client.

    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

  3. 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.
  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.

    Optionally, for WebSphere MQ publish/subscribe messaging, install a Publish/Subscribe broker, such as WebSphere MQ Event Broker to gain full publish/subscribe functionality. Refer to the installation instructions for the other broker for hints and tips on installation.

    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:
