Fix Pack 8550

Installing and uninstalling Liberty interim fixes and fix packs on distributed operating systems

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.
