Additional software prerequisites

WebSphere Event Broker requires additional software products to run successfully.

The required software products are shown in the table below. Except where listed, the Java™ Runtime Environment is embedded with WebSphere Event Broker. WebSphere MQ Version 6.0 (with tailored terms and conditions for use with WebSphere Event Broker) is supplied on CD or DVD (on Linux (x86 platform) and Windows only). If you have a previous version, you can use the supplied CDs or DVD to upgrade your current installation.

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 Event 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 Event Broker.

  2. WebSphere Event 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 Event 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.
    • 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 Event 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 offerings do not install Mozilla by default. If you plan to install the Message Brokers Toolkit on your Linux system, check that a supported version of Mozilla is already installed. If not, install Mozilla from your Linux operating system media.
  5. On z/OS, WebSphere MQ is a mandatory requirement and must be installed before you install WebSphere Event Broker. See the Program Directory for WebSphere Event Broker for z/OS or the Program Directory for WebSphere Rules and Formatter Option for z/OS for further details.

For best results when viewing the information center from the Message Brokers Toolkit, you are recommended to use Internet Explorer Version 6.0 or higher.
