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.
Before you begin
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.
- Overview of the enhancements with the Feature Pack for Web Services
The Feature Pack for Web Services includes these enhancements for the
Update Installer:
- Upgrading software for the Update Installer
- Installing multiple fixes to multiple products during the maintenance
installation process
- Enabling interim fix installation support.
- Allowing for operating system prerequisite checking
- Linking to the maintenance download wizard to obtain the latest maintenance
- Overview of installing WebSphere Application Server fix packs with feature
packs
The feature pack enabling interim fix contains the WebSphere Application
Server enablement code that is used by all feature packs. It is packaged inside
each WebSphere Application Server fix pack. When a fix pack is installed and
no feature packs have been installed, this interim fix will be saved for future
use. The interim fix will be installed when ever a feature pack is installed.
The enabling interim fix contains the changes for all feature packs. This
interim fix 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 enabling interim
fix associated with the fix pack is uninstalled and a previous version of
enabling interim fix associated with older fix pack will be installed. The
versionInfo utility can be used to show any interim fixes which have been
installed.
About this task
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.
The Update Installer wizard
uninstalls in two modes: the
silent mode and the graphical user interface mode.
- Using the silent uninstall, the procedure for uninstalling a fix pack,
or interim fix, or interim feature are similar. For more information about
uninstalling using the silent uninstall, refer to Uninstalling a fix pack, an interim fix, a test fix using the silent uninstall.
- Using the graphical user interface, the procedure for uninstalling is
similar for both fix packs, interim fixes, or interim features. The Update
Installer allows for only one fix pack, interim fix, or interim feature to
be uninstalled at a time. To uninstall more than one, you need to re-start
the Update Installer. To find out more about uninstalling a fix pack or refresh
pack, refer to Uninstalling fix packs, interim features, test fixes, or fix packs delivered as a CIP slip install.
