Apply an interim fix to a Liberty profile archive install

Liberty profile offers a self extracting archive based install as an alternative to using IBM Installation Manager. If we installed the Liberty profile using the self extracting archive, and want to install an interim fix, we can apply an executable jar file. Note: If we used IBM Installation Manager to install Liberty profile, use Installation Manager to apply an interim fix.

An interim fix is named <Liberty profile level>-WS-WASProd_WLPArchive-<fix type><fix id>.jar

• <Liberty profile level> refers to a 4 digit fix pack level identifier, which indicates the minimum level to which the fix applies. For example, 8.5.0.0.
• <fix type> refers to the type of fix. For example IF is used for an interim fix, and TF for a diagnostic fix
• <fix id> refers the APAR reference number. If a diagnostic fix is provided before an APAR is opened, the <fix id> will be based on the PMR reference number.

Each interim fix is installed by executing the relevant jar file, which uncompresses the content into the Liberty profile base folder (/wlp)

When the interim fix is applied, no back up data is created. If an interim fix needs to be backed out, you must manually remove files and/or restore files, from under the /wlp folder. Each interim fix is provided with a readme.txt file, which contains back up and restore instructions specific to the fix content in a section titled Directions to apply fix. If the readme.txt does not include any requirement to back up files, we can extract the fix and then restart the server at any time with the --clean parameter as a launch option.

1. Optional: If the fix contains files that will overwrite existing files, stop all servers running on the system.
2. Optional: If the readme.txt indicates a back up is required, create a back up of the lib/features/component.mf files. File locations are relative to your Liberty profile install root.
3. Open a console and direct it to the location of your interim fix jar file.
4. To view available options, run java -jar wlp-edition-8.5.0.0.jar -help. The following launch options are available for the jar:

   --installLocation

   The absolute or relative location of the Liberty profile install directory.

   By default the jar will look for a wlp directory in its current location. If wer Liberty profile install location is different to wlp and/or is not in the same directory as the jar, then we can use this option to change where the jar will patch. [LibertyRootDir] can either be relative to the location of the jar, or an absolute file path.

   --suppressInfo

   The only messages output from the JAR file will be error messages or confirmation that patching has completed.

5. Select the install location.
6. Start all Liberty profile servers with the --clean parameter as a launch option. For example, server start --clean. The --clean option only needs to be used once, all subsequent server starts will not require it.
