Notes:
  1. The minimum set of components that you must install are the server and Java Messaging components. You can install WebSphere MQ before or after you install WebSphere Message Broker.

    If you have WebSphere MQ Version 5.3 already installed, the Java Messaging component is not installed by default. Check that your installation includes it; add this component from the WebSphere MQ Version 5.3 CD if it is not installed.

    If you choose to install WebSphere MQ Version 6 from the Windows Launchpad, Express installation installs all required components for you. If you use Advanced installation, you must select a custom installation and include the server and Java Messaging components.

    If you start the WebSphere MQ Version 6 installation program directly on any platform, including Windows, you must select a custom installation and include the server and Java Messaging components.

    Other components are optional for use with WebSphere Message Broker.

  2. WebSphere Message Broker requires a full WebSphere MQ product and cannot function correctly with the WebSphere MQ product that is included with WebSphere Application Server Version 5 (known as Embedded Messaging).

    You cannot install WebSphere MQ if you already have WebSphere Application Server Version 5 installed, because you cannot upgrade the Embedded Messaging component to the full WebSphere MQ product. You must uninstall WebSphere Application Server Version 5, install WebSphere MQ, then reinstall WebSphere Application Server Version 5.

    WebSphere Message Broker is fully compatible with WebSphere Application Server Version 6. You do not have to take any special action for these products to interact successfully.

  3. For some specific broker functions, later levels are recommended:
    • If you are running publish/subscribe applications that use WebSphere MQ Real-time transport, WebSphere MQ Version 5.3.0.10 or later might be required if you experience problems in a heavily loaded broker system.
    • If you develop message flows that include the MQOptimizedFlow node, you must install WebSphere MQ Version 5.3.0.10 or later on each affected broker system.
    • Support for JMS SSL requires WebSphere MQ Version 5.3.0.11 or later.
    • If you develop message flows that use WebSphere MQ Real-time Transport with Multicase PGM support, you must install WebSphere MQ Version 6.0 or later on each affected broker system. An iFix is also required; see the readme.html file for the latest information.
    • To exploit the Native POSIX Threading Library (NPTL) performance gains on Linux systems (available with Kernel 2.6 and above), which support multiple threads running within one process, you must install WebSphere MQ Version 6.0. Performance gains might be achieved where you have multiple message flows assigned to a single execution group.
    For z/OS, see the Program Directory for WebSphere Message Broker for z/OS or the Program Directory for WebSphere Rules and Formatter Option for z/OS for further details about required levels of WebSphere MQ.
  4. Some Linux (x86 platform) offerings do not install Mozilla by default. If you plan to install the Message Brokers Toolkit on your Linux (x86 platform) system, check that a supported version of Mozilla is already installed. If not, install Mozilla from your Linux (x86 platform) operating system media.
  5. On z/OS, WebSphere MQ is a mandatory requirement and must be installed before you install WebSphere Message Broker. See the Program Directory for WebSphere Message Broker for z/OS or the Program Directory for WebSphere Rules and Formatter Option for z/OS for further details.
