Additional software requirements

WebSphere® Message Broker requires additional software products to run successfully.

WebSphere MQ

All WebSphere Message Broker components require WebSphere MQ at the minimum supported level shown in the table.

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

Start of changeAll runtime components (broker, Configuration Manager, and User Name Server) require a WebSphere MQ queue manager. Each component of the same type must have a dedicated local queue manager. More than one broker cannot share a single queue manager; this restriction also applies to Configuration Manager and to User Name Server components. Components of different types can share a queue manager; for example, a broker and a Configuration Manager on a single computer can share a queue manager.End of change

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 Message Broker.

    If you have already installed WebSphere MQ Version 5.3, 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 on x86 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 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 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.
    • Support for JMS Real-time nodes requires 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 6.0.1.0 (or later) on each affected broker system.
    • 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.
    • If 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.)
  4. 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 Message Broker with Rules and Formatter for z/OS for further details about required levels of WebSphere MQ.

For details of WebSphere MQ products and supported versions, see the WebSphere MQ product information 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 option; 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. You must change your configuration if you want to use this alternative level of Java; see Command environment: Linux and UNIX systems.
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 Customizing the version of Java on z/OS and 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 on x86.

Some Linux on x86 offerings do not install Mozilla by default. If you plan to install the Message Brokers Toolkit on your Linux on x86 system, check that a supported version of Mozilla is already installed. If not, install Mozilla from your Linux on x86 operating system media.
