Notes:
  1. Always check the readme.html file for the latest information about supported software. A readme file is supplied on the product DVD or CD (for runtime components and for the Message Brokers Toolkit), and you can access it from the final panel of the relevant installation program. However, the files are updated occasionally; access the product readmes Web page to check that you have the latest level.
  2. Start of changeOn all Linux systems on which you plan to use Rational Agent Controller, ensure that the X Windows libraries are installed before you install WebSphere Message Broker. If you have a 64-bit platform, you must install the 31-bit or 32-bit X Windows libraries in addition to the 64-bit libraries.

    If you are installing on Red Hat Enterprise Advanced Server V4.0, you must also install the deprecated X Windows libraries.

    All these libraries are available with the operating systems media.

    End of change
  3. The Message Brokers Toolkit is supported on Linux Intel (32-bit) Red Hat Enterprise Linux Advanced Server V3.0 and Linux Intel (32-bit) SUSE Linux Enterprise Server (SLES) 9 only.

    Linux x86 (64-bit) Red Hat Enterprise Linux AS V4.0 supports broker components only. WebSphere Message Broker is a 32-bit application and requires 32-bit C and C++ libraries, which are available through the Red Hat Enterprise Linux compatibility hardware architecture runtime support options.

  4. On Linux (x86 platform), you might require the following additional packages which are available with the operating system:
    • If you chose to install in graphical mode, compatibility libraries are required:
      • Red Hat Enterprise Advanced Server 3.0: package compat-libstdc++
      • SUSE LINUX Enterprise Server: package compat (at version 2002.12.6.0 or later)
      These libraries are not required for console or silent installations.
    • If you want to use the package monitor (RPM), the rpm-build package is required.
  5. Start of changeOn Linux (zSeries platform), WebSphere Message Broker operates in 31-bit mode on 64-bit versions. Ensure that 31-bit versions of the C and C++ libraries, WebSphere MQ, and DB2 are installed.End of change
  6. This patch provides multithreaded malloc support on Solaris 8. It is required because the standard system malloc library is optimized for single-threaded applications, but the broker typically runs many threads and requires the multithreaded mtmalloc.
  7. WebSphere Message Broker is supported only in the Global zone, or in a whole root non-global zone, and must be installed separately in each.
  8. 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. In particular, review the information in "Preventative Service Planning".
