What is new with Fix Pack 9
One installation of Version 6.1 Update Installer can be used to update all WebSphere Version 6.1 products installed on the entire machine. There is no longer a need to install one copy for each product install location.

However, Fix pack must be installed by Update Installer version or later. If earlier versions of Update Installer (i.e, version or are used, prerequisite checking will fail with the following message:

"Prerequisite checking has failed. Failure messages follow:
A general exception has occurred during prerequisite checking. Check the log files for more information."

Users will see the following in the log file: ClassNotFoundException for StackDependencyPrereqChecking.

The Update Installer is no longer bundled with version 6.1 fix packs. It is available on the Version 6.1 product compact disc or as a download from IBM support site. See section on Prerequisites for installing Fix Pack 9 for more details.

About Fix Pack 9
Several cumulative fixes are bundled into a single maintenance package for a specific combination of product and platform. Each maintenance package is referred to as version

Installing Fix Pack 9 with version 6.1 Update Installer raises the fix level of your product to version

See the installation instructions in the Steps for installing Fix Pack 9 section for more information.

Fix packs can be downloaded from the version download page.

Note: If a remote Web server plug-in or IBM HTTP Server is installed alongside WebSphere Application Server, you will need to download a separate fix pack in order to update the plug-in or HTTP Server to the most current level (if an update is available). All fix packs can be found on the version download page.

  1. Install the version 6.1 product from the appropriate compact disc or distribution media.

Space requirements
Space requirements vary depending on what you are installing. The size of each download is available on the Support site. For a fix pack, you need approximately 600 MB of free space in the system temporary directory (typically /tmp on a Linux® or UNIX® system) and another 600 MB in the file system that hosts the WebSphere Application Server image (typically /usr or /opt on a Linux® or UNIX® platform), or approximately 1.2 GB of free space on the disk drive where you are installing on a Windows® platform.

Verify that the free space is available before beginning the installation.

Space is also required for backup files in the WebSphere Product's install_root /properties/version/update/backup directory. The space required is about the same as the size of the fix pack, somewhere between 25 MB to 750 MB, varying by product and platform.
