Preparing Red Hat Enterprise Linux 6 for installation
You must complete additional steps to prepare a Red Hat Enterprise Linux Version 6 system for a WebSphere® Application Server installation.
Before you begin
Complete all steps in Preparing Linux systems for installation. Those steps are common to any Linux system.
About this task
In addition to the common steps required for installing any Linux system, a few system-specific steps are required for Red Hat Enterprise Linux Version 6.
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.
Procedure
Install the following packages on any hardware platform:
- Required for C++ runtime compatibility; used by such components as GSKit, the Java™ 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
- Required by IBM HTTP Server
- Required by the IBM Installation Manager
- Required by the IBM Installation Manager
- Required by the Java SDK to provide printing functions for
graphical user interfaces
Without this package, Swing-based applications and AWT-based applications cannot instantiate.
- Required to install the application server using a user interface.
These packages are part of the Red Hat Enterprise Linux 6 operating system, but they might not install by default. You can also install a later release of any of these packages if Red Hat provides new packages as errata.
Results
If you do not install all of the required packages, the installation will not perform as intended. Error messages indicate missing libraries, the inability to load graphical interfaces, or other errors that occur during the installation.
- Installing with a non-graphical user interface and with the IBM Installation Manager requires only a minimal operating system install, which typically already includes packages: glibc, libgcc, and nss-softokn-freebl.
- Installing with a graphical user interface and with the IBM Installation Manager requires gtk2 and its transitive dependencies.
- Various components, features, and tools in the product depend on the rest of the packages. This relationship is sometimes enumerated alongside the package.
