Additional software requirements

WebSphere Event Broker requires additional software products to run successfully:

WebSphere MQ

WebSphere MQ is required for all WebSphere Event Broker components at the minimum supported level shown in the table below.

WebSphere MQ Version 6.0 (with tailored terms and conditions for use with WebSphere Event Broker) is supplied on CD or on DVD (on Linux (x86 platform) and Windows only). If you have a previous version of WebSphere MQ, you can use the supplied CDs or DVD to upgrade your current installation.

Notes:
  1. As a minimum, you must install 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.

    If you want to use the WebSphere MQ Explorer, the graphical interface that is available on Linux (x86 platform) and Windows only, install the WebSphere Eclipse Platform Version 3.0.1 and the WebSphere MQ Explorer 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 might be required:
    • 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) on each affected broker system.
    • Start of changeSupport for JMS Real-time nodes requires WebSphere MQ Version 5.3.0.10 (or later) on each affected broker system.End of change
    • Start of changeIf you develop message flows that use WebSphere MQ Real-time Transport with Multicase PGM support, you must install WebSphere MQ Version 6.0.1.0 (or later) on each affected broker system. End of change
    • 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 (or later). Performance gains might be achieved if you have multiple message flows deployed to a single execution group.
    • To exploit 64-bit execution groups, you must install WebSphere MQ Version 6.0 (or later) on each affected broker system.
    • Start of changeIf you use DB2 Version 9.1, you must install WebSphere MQ Version 6.0.2.0 on each affected broker system. (DB2 Version 9.1 is not supported on z/OS.)End of change
  4. 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 for further details about required levels of WebSphere MQ.

For details of WebSphere MQ products and supported versions, see the WebSphere Integration products system requirements Web site.

JRE

A Java™ runtime environment (JRE) is required. The minimum supported version is Version 1.4.2; Version 5 (also known as Java 1.5) SR2 is also supported.

Distributed systems
  • Java Version 1.4.2 is embedded in the product components. This version is the product default; no configuration is necessary if you require this level of support. All components that are installed and created on this system will use Java 1.4.2.
  • Java 5 SR2 is supplied with the product components. If you want product components to use Java 5 SR2 instead of the embedded Java 1.4.2, configure your command environment to access this optional version. If you make this change, all components that are installed and created on this system will use Java 5 SR2.
z/OS
  • Java 1.4.2 (Fix Pack 2) is supported but must be separately installed. Customize the profile of each component that you install and create on this system to use Java 1.4.2 if appropriate.
  • Java 5 SR2 (32-bit) is supported but must be separately installed. Customize the profile of each component that you install and create on this system to use Java 5 SR2 if appropriate.

For additional information, see the Java 2 on z/OS Web site.

Rational Application Developer

The Message Brokers Toolkit includes components of the Rational® Application Developer (RAD) integrated development environment. These components provide a common Rational framework that is shared with other compatible Rational products if one or more such products are installed on the same system.

For further information about RAD and the Message Brokers Toolkit, see the Installation Guide.

Browsers

For best results when viewing the information center from the Message Brokers Toolkit, use Internet Explorer Version 6.0 (or later) on Windows, or Mozilla 1.4.2 (or later) on Linux (x86 platform).

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.
