The official statements of support for WebSphere Application Server products are provided online at the Supported hardware and software Web page.
See Supported hardware and software Web page for the complete up-to-date listings on what is supported.
If there is a conflict between the information provided in the information center and the information on the Supported hardware and software pages, the information at the Web site takes precedence. Prerequisites information in the information center is provided as a convenience only.
Space is also required for the installable components in the secondary packet of the product package. Refer to the documentation for each installable component to determine exact space requirements.
Disk space requirements vary according to the hardware platform. See Preparing the operating system for installation for information about required disk space and how to prepare your operating system for installation:

As mentioned, the official statements of support for operating systems are on the Supported hardware and software site.
The installation programs for WebSphere Application Server products verify that a supported operating system is installed. The verification includes checking for required patches with the prereqChecker application.
Although the Installation wizard checks for prerequisite operating system patches, review the prerequisites on the Supported hardware and software Web site if you have not already done so.
Always consult the Supported hardware and software Web site to determine whether your operating system is supported when you receive a message from the prereqChecker program. In some cases, the Web site will be more current than the prereq checker on a product disc. For example, IBM often declares support for new versions of operating systems for a product that is already released. The prereqChecker might issue a message when, in fact, a new version of an operating system is supported.
The Web site lists all supported operating systems and the operating system fixes and patches that you must install to have a compliant operating system.
If you get an error from the prereqChecker program, you can continue the installation. PrereqChecker errors do not prevent you from installing. The messages are notifications of potential problems that you can ignore if the Web site lists your operating system as supported.
Refer to the product documentation for non-IBM prerequisite and corequisite products, such as browsers, to learn how to migrate to supported versions.

Mozilla 1.7 might not be available on your native language and operating system combination. In addition, certain versions of Mozilla are required for WebSphere Application Server Network Deployment on certain operating system platforms.
Versions of Mozilla earlier than 1.7 have known security exposures. Details regarding these security exposures are available from the Mozilla Web site: http://www.mozilla.org/projects/security/known-vulnerabilities.html
The
launchpad application can fail to start the ISMP installer on AIX 5L if Mozilla
1.7.8. or later is not installed. The installation image for the 64-bit WebSphere
Application Server Network Deployment for
AIX product (Version 6.0.2) requires Mozilla 1.7.8 or later to run the installer
from the launchpad. See Preparing AIX systems for installation.
Mozilla frequently adds to the list of native languages and operating system combinations that are supported on Mozilla releases, so check their Web site for updates: http://www.mozilla.org/releases/
In addition, WebSphere Application Server Network
Deployment for Linux (Version 6.1) requires Mozilla Firefox to support
Gnome and KDE menu entries. See Preparing Linux systems for installation.
