You can use IBM® Installation Manager to update the
product with the fix packs that are available for your service level of the product. Uninstalling
fix packs to a previously installed level is called rolling back.
Before you begin
For the most current information about upgrades for WebSphere® Application Server and its associated software, see the IBM Software Support Center and Fix Central.
For a list of fix packs that are available for WebSphere Application Server and its associated software and for specific information about each fix pack, perform the
following actions.
- Go to Fix
Central.
- Select the Select product tab.
- Select WebSphere as the product group.
- Select WebSphere Application Server as the product.
- Select the version of the product to be updated.
- Select your operating system as the platform, and click Continue.
- Select Browse for fixes, and click Continue.
- Click More Information under each fix to view information about the
fix.
About this task
Important: Installation Manager can install any fix-pack level of the product directly;
in fact, Installation Manager installs the latest level by default. For example, you can skip
fix-pack levels and go from Version 9.0.0.1 directly to Version 9.0.0.5. Keep in mind, however, that
later you can not roll back to any level that was skipped. If you directly install to Version
9.0.0.5, for example, you cannot roll back to Version 9.0.0.3. If you skip from Version 9.0.0.1 to
Version 9.0.0.5, you can only roll back to Version 9.0.0.1. You should plan your installations
accordingly.
When you install a fix pack, Installation Manager automatically reapplies any installed interim
fixes if they apply to the updated fix pack level. Interim fixes that do not apply, such as if the
updated fix pack contains the fix, are uninstalled. In some cases, Installation Manager must
uninstall an interim fix that you must manually reapply. For example, you might update to a fix pack
that does not contain the fix and requires an updated interim fix level. Installation Manager
notifies you if any interim fixes must be manually reapplied. You can verify which interim fixes are
installed by running the versionInfo -ifixes command.
Tip: You can use the IBM Packaging Utility to generate a new local or web-based
repository that contains all of the fixes that you want to install and then use Installation Manager
to update the product with all of the fix packs as a group. For information on using the Packaging
Utility, see the
IBM Installation Manager
documentation.
Avoid trouble: The IBM i group
PTFs are no longer provided in
WebSphere Application Server
Version 9.0. To install the newest WebSphere Application Server fix pack on IBM
i, make sure that you apply the necessary cumulative package and the group PTF levels listed in
WebSphere Application Server for IBM i. Apply the fix pack by using the
IBM Web Administration for i Console or by using
Installation Manager.
