How to upgrade the embedded WebSphere Liberty profile installed with Engineering Lifecycle Management applications

How To


These instructions assist administrators in upgrading the version of WebSphere Liberty that is embedded within the Engineering Lifecycle Management applications.


These instructions apply to versions 6.0.6 and higher.
IBM WebSphere Liberty is the latest version tested for use with the product suite.
Note: Since Jazz Authorization Server (JAS) uses a different installation method, the following upgrade process does not work for JAS.
Users must use this technote instead.


  1. Locate and download the wlp-core-all-<version>.jar file from Fix Central
    1. Open Fix Central:
    2. In the “Product Selector” field, enter “WebSphere Liberty”
    3. For “Installed Version”, select “ALL”
    4. For “Platform”, select “ALL”
    5. Click “Continue”
    6. Select “Browse for fixes”, click “Continue”
    7. After the page loads fully, there will be a “Search” box that appears in the upper right near the “Release Date” column.  In this field, enter the version number you are looking for (example: followed by a space and then the word “jar” to narrow down the selections.
    8. In the shortened list, you can find an entry for wlp-core-all- (or which ever specific version you searched for).  Download this file
  2. Transfer the file to your server
  3. Create a temporary location (example: Linux®: /tmp/liberty_update; Windows®: c:\temp\liberty_update)
  4. Execute the JAR file with the command
    • java -jar wlp-core-all-
      *If you receive an error message executing Java™ commands, your JAVA_HOME environmental variable might not be set.
  5. Accept the license agreements
  6. Hit enter to continue to use the targeted temporary folder that you created in Step 3 to “install” Liberty into.
  7. Change directory to the JAZZ_HOME/server directory
