Preparing Red Hat Enterprise Linux 4 for installation
You must complete additional steps to prepare a Red Hat Enterprise Linux V4 system for a WAS installation.
Before you beginComplete steps 1-10 in Preparing Linux systems for installation . Those steps are common to any Linux system.
About this taskIn addition to the common steps required for installing any Linux system, a few system specific steps are required for Red Hat Enterprise Linux V4.
Verify that the prerequisite packages are installed. A Linux package registration limitation prevents the prerequisites checker program from examining prerequisite packages on Linux systems. See Installing and verifying Linux packages for more information.
- Install packages for all hardware platforms.
Install the following packages on any hardware platform:
- Required for C++ runtime compatibility. Used by such components as GSKit, the Java 2 Software Development Kit (SDK), and the Web server plug-ins.
- Required by IBM HTTP Server. Some of the modules use the libraries contained within this package.
- xorg-x11-deprecated-libs-6.8.1 or xorg-x11-deprecated-libs-6.8.2
- Required by the Java 2 SDK to provide printing functions for graphical user interfaces. Without this package, Swing-based applications and AWT-based applications, such as InstallShield for Multiplatforms (ISMP), cannot instantiate.
- Required by ISMP to properly register products within the RPM database.
These packages are part of the Red Hat Enterprise Linux 4 operating system, but are not installed by default. You can also install a later release of any of these packages if Red Hat provides new packages as errata.
Hardware platforms capable of running both 32-bit and 64-bit applications include Opteron, EM64T, iSeries, pSeries (PowerPC), and zSeries (S/390 64-bit) machines.
By default, RHEL 4 only installs 64-bit runtime support on these platforms. However, various applications included with WAS V6.x products and packages also require the 32-bit runtime support. Therefore, install the 32-bit runtime support.
Install the following required 32-bit packages by selecting to customize the packages during the RHEL 4 installation. Or, customize packages on an existing RHEL 4 system by issuing the system-config-packages command from a graphical terminal.
Install the Compatibility Architecture Support under the System category. Optionally install the Compatibility Architecture Development Support under the Development category if you intend to build C or C++ libraries for use with both 32-bit and 64-bit applications.
Platforms that support both 32-bit and 64-bit applications require both the 32-bit and 64-bit versions of the following packages:
Run the rpm -qa | grep package_name command to verify that you have both versions of each package. Substitute the name of each package for the package_name variable.
Installed packages are displayed in the reply to the command. If you do not get two replies for each package, you have only one version of the package installed. You must then install the missing package.
In addition to the packages that are common to all platforms, install the following packages on hardware platforms capable of running both 32-bit and 64-bit applications before installing WAS products and packages.
Install both the 32-bit version and the 64-bit version of the package on 64-bit z/Series hardware platforms.
After installing the v6 WebSphere Application Server product or package, install the latest refresh pack. The RHEL 4 operating system is supported beginning with v6.1 (Refresh Pack 1).
