In general rolling back a maintenance package from a WebSphere® ESB installation
that was created with a customized installation package (CIP) is the
same as the procedure for other installations. However, there are
specific differences which are described here.
Before you begin
This task is appropriate if you have an installation of
WebSphere ESB that
was created with a CIP, to which a maintenance package has been applied
in one of a variety of ways. You must use the Update Installer for WebSphere software to roll
back maintenance from a CIP installation.
About this task
The core information for rolling back maintenance packages
is contained in the related task: Uninstalling maintenance packages.
Additional steps for uninstalling maintenance packages from
WebSphere ESB installations
that were created with a CIP are described below.
Procedure
- After you slip install a CIP onto an existing WebSphere ESB installation
you want to uninstall maintenance, without uninstalling the entire
product. The CIP consists of a merged refresh pack, fix pack, and
one or more interim fixes.
- Uninstall any interim fixes that were installed as part
of the slip installation.
- Roll back the maintenance levels that were contained
in the CIP. This is identical to uninstalling a single fix pack or
refresh pack except that whatever maintenance had been rolled up into
the CIP is rolled back in a single operation. This means that it is
not possible to roll back just the fix pack portion of a CIP and leave
the installation at the refresh pack level, both will be rolled back
at once, leaving the installation in the same state it was in before
the slip install was performed.
- After a slip installation you want to remove maintenance
that was installed prior to the slip installation.
- Roll back the slip installation.
- Roll back the maintenance package as described in the
related task: Uninstalling maintenance packages.
- After adding an interim fix to a WebSphere ESB installation
that was created with a CIP. This procedure is independent
of the method of WebSphere ESB installation.
- After adding an fix pack or refresh pack to a WebSphere ESB installation
that was created with a CIP. This procedure is independent
of the method of WebSphere ESB installation.
