The Liberty profile offers a self-extracting archive-based
installation as an alternative to using IBM® Installation Manager. If you installed the Liberty profile
using the self-extracting archive, and want to install an interim
fix, you can apply an executable JAR file.
About this task
If you used IBM Installation
Manager to install the Liberty profile, you must use Installation
Manager to apply an interim fix.
An archive-based 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, 8.5.5.0.
- <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 to the APAR reference number.
If a diagnostic fix is provided before an APAR is opened, the <fix id> is based on the PMR reference number.
Each interim fix is installed by executing the relevant
JAR file, which extracts the content into the Liberty profile base
folder (/wlp).
Note: When the interim fix
is applied, no backup data is created. If you want to back out an
interim fix, you must manually remove or restore files from the /wlp folder.
Each interim fix is provided with a
readme.txt file, which contains backup and restore instructions
specific to the fix content, in a section titled
Directions
to apply fix. If the
readme.txt file
does not specify any requirement to back up files, you can extract
the fix and then restart the server at any time with the
--clean parameter as a launch option.
