Hardware and software requirements

This topic describes prerequisites for installing WebSphere Application Server products.

The official statements of support for WAS products are provided on the Supported hardware and software Web page at the http://www.ibm.com/software/webservers/appserv/doc/latest/prereq.html IBM Web address. If there is a conflict between the information provided in this document and the information on the Supported hardware and software Web address, the information at the Web site takes precedence. The information in this document is provided as a convenience only.

Required disk space

Disk space requirements are platform-specific. See the following topics for information about required disk space and how to prepare your operating system for installation:

Additional space is required for the installable components in the secondary packet. Refer to the documentation for each installable component to determine exact space requirements.

Supported operating systems

The official statements of support for the WebSphere Application Server products are provided on the Supported hardware and software Web page at the http://www.ibm.com/software/webservers/appserv/doc/latest/prereq.html IBM Web address.

The installation programs for WAS 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 IBM WebSphere Application Server supported hardware, software, and APIs Web site if you have not already done so. Refer to the documentation for non-IBM prerequisite and corequisite products to learn how to migrate to their supported versions.

Always consult the IBM WAS supported hardware, software, and APIs Web site to determine whether your operating system is supported when you receive a message from the prereqChecker program. The Web site lists all supported operating systems and the operating system fixes and patches that install to have a compliant operating system.
