Before beginning an installation, it is important that you think about the type of WAS install you wish to perform.
The WAS installation process requires two main actions:
1. Installation of base binaries (which are the core executable).
2. Profile creation.
A conceptual diagram of the WAS installation components is shown next:
Preparation and prerequisites
Before we start with the WebSphere Application Server installation, we need to ensure the correct installation media is available and that the operating system prerequisites have been met.
- What version of WAS is required to support your applications?
- Are there any OS parameters for the platform required for the chosen version of WAS?
- What version of OS and fix packs are required to support the chosen version of WAS?
- Identify the filesystem where you will be installing the Websphere binaries and the path where you will have the profile created
- Those filesystems is recommended to be on a separate partition should have sufficient space and also for the logs
- Have atleast 1GB for the /tmp folder
- Have the root access or the sudo access
Part 1—Installing the base binaries
Details of the Server : Red Hat Enterprise Linux Server release 5.6

WAS Version: WAS ND 8
The WAS v8 installation GUI has been changed since WAS v7. IBM has updated many of its products to use a common Java-based installation tool called the IBM Installation Manager (IIM).
Downloading WAS 8

The WAS v8 installation GUI has been changed since WAS v7.
A major benefit is that IIM provides a common installation interface for many products
Prior to the WAS 8 release, each OS version of WAS required separate downloads.
Using a repository system now saves many hours of download and also disk space and simplifies the management of different installation packages.
