Interim fixes provide corrective service for specific known
problems. Fix packs contain bundled service to bring WebSphere® Application Server Liberty Network Deployment up to a new level. You can
use IBM® Installation Manager
to update the offering with the interim fixes and fix packs that are
available for your service level of WebSphere Application Server Liberty Network Deployment.
Before you begin
Contact the IBM Software
Support Center for information about updates for WebSphere Application Server Liberty Network Deployment. The most current information
is available from the IBM Software
Support Center and Fix Central.
IBM Installation Manager is used to apply and
remove maintenance.
Important: Installation Manager
can install any fix-pack level of the product directly without installing
the intermediate fix packs; in fact, Installation Manager installs the
latest level by default. For example, you can skip fix-pack levels
and go from Version 8.5.5.1 directly to Version 8.5.5.5. Keep in
mind, however, that later you can not roll back to any level that
was skipped. If you directly install to Version 8.5.5.5, for example,
you cannot roll back to Version 8.5.5.4. If you skip from Version
8.5.5.1 to Version 8.5.5.5, you can only roll back to Version 8.5.5.1.
You should plan your installations accordingly.
Note: In WebSphere Application Server Version
8.5.5.0, the Liberty profile was promoted from a feature to an independently
installable offering. After updating to WebSphere Application Server Liberty Network Deployment Version
8.5.5.x from Version 8.5.0.x,
you can roll back to the Version 8.5.0.x Liberty
profile feature level that you were at before updating. If you previously
had a combined full-profile and Liberty-profile installation, the
Liberty profile feature will be reinstalled to the wlp folder
when you roll back. Any user data and server configurations will
not be restored. If necessary, you can copy them from the backed-up
location into the new wlp/usr folder after rollback.
If any wlp.bak_<timestamp> directories
are present in your installation image, they will not be affected
by the rollback. If you update and roll back multiple times between
Version 8.5.0.x and Version 8.5.5.x levels,
therefore, you will have multiple wlp.bak_<timestamp> folders
in your installation image. These can always be deleted, copied,
or moved without negative impact to your installation.
About this task
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 WebSphere Application Server Liberty
Network Deployment with all of the interim fixes
as a group. For information on using the Packaging Utility, see the
IBM Installation
Manager Information Center.
