This feature allows you to upgrade to a newer maintenance
level using a customized installation package (CIP).
Before you begin
To install interim fixes, fix packs, and refresh packs, collectively
known as maintenance packages, you must have an existing
WebSphere® ESB installation.
The existing product installation level must be a lower level than
the maintenance package that you want to install.
You can obtain
a
WebSphere ESB CIP
in two ways, from the disks in the product package or by downloading
installation images from the Passport Advantage® site, if you are
licensed to do so.
Note: For detailed installing instructions, please
refer to the instructions provided with your fix pack or refresh pack.
Attention: Fix packs that include updates
to the Software Development Kit (SDK) might overwrite unrestricted
policy files. Back up unrestricted policy files before you apply a
fix pack and reapply these files after the fix pack is applied.
To
install a maintenance package using a CIP, perform the following steps.
Procedure
- Determine the maintenance level of the existing WebSphere ESB installation.
The installed product must be at a lower maintenance level then the
maintenance upgrade you will apply. You can check the existing version
using the versionInfo script. See Product version and history information for more details.
- Follow the procedure in the Installing WebSphere ESB interactively topic.
- After completing the installation, you can use the versionInfo script
to verify that the installation is at the updated maintenance level.
