The IBM Update Installer for WebSphere Software allows for installing and uninstalling interim fixes, fix packs, and refresh packs. The Update Installer for WebSphere Software is also known as the Update Installer program, the UpdateInstaller program, and the Update installation wizard.
Use the proper authorizations to successfully install product updates.
Use the Update Installer
program from the same user ID that installed the product that you are updating.
Otherwise, the file ownership mismatches might require correction by the root
user. See Using root or non-root when installing with the Update Installer for more information.
Use
the Update Installer program from a user profile with *ALLOBJ special authority.
When a fix pack is installed and no feature packs have been installed, all enabling interim fixes will be saved in a special directory for future use. When the first feature pack is installed, then the common enabling interim fix and the feature pack specific enabling interim fix will be installed. If a new fix pack level is installed, the common enabling interim fix and each feature pack specific enabling interim fix will be installed for that level. The Update Installer will ensure that when a WebSphere Application Server fix pack is applied, the common enabling interim fix is applied plus all appropriate enabling interim fixes for each specific feature pack.
All enabling interim fixes, both common and those specific to feature packs are packaged inside each WebSphere Application Server fix pack. These enabling interim fixes will not be accessible through the support pages or available as a separate user installable or uninstallable maintenance package.
When installing a fix pack, the Update Installer will inform you about changes to support the feature pack. When uninstalling fix packs, the common enabling interim fix associated with the fix pack is uninstalled and a previous version of an enabling interim fix associated with older fix pack will be installed. This process to restore older enabling interim fixes will also occur for each feature pack specific enabling interim fix. The Update Installer will ensure that when uninstalling the WebSphere Application Server fix pack back to aprevious levels, the common enabling interim fix plus all appropriate enabling interim fixes for each specific feature pack is also restored to previous levels. The versionInfo utility can be used to show any interim fixes that have been installed.
For an overview of the procedure for installing maintenance using
the Update Installer, refer to
Installing maintenance packages.
Now you can upgrade the Update Installer and get the latest version. The maintenance download wizard will step you through the required selection panels to identify the recommended version for your environment. For more information, refer to Upgrading the Update Installer.
The Update Installer wizard installs maintenance packages in two modes: the silent mode and the graphical user interface mode.
The i5/OS platform installs in only silent mode, working
at the Qshell command line.
