Plug-in version mismatch after the master domain manager upgrade

After upgrading the master domain manager to V10.2.7, a version mismatch occurs between the plug-in JAR files in different directories.

You may observe the following version discrepancy:
  • /TWS/applicationJobPlugIn/: Contains the manually updated (newer) version.
  • /TWS/JavaExt/eclipse/plugins/: Contains the version bundled with the 10.2.7 package (older).

Cause

The upgrade process overwrites the file in the JavaExt directory with the version included in the installation package but does not update the file in the applicationJobPlugIn directory. This results in the agent potentially using an outdated plugin version.

Resolution

To resolve the version mismatch and ensure the agent uses the latest plugin features, manually synchronize the JAR files:
  1. Navigate to the directory containing the latest version of the plugin: /TWS/applicationJobPlugIn/
  2. Identify the JAR file: com.ibm.scheduling.agent.<plugin_name>_<plugin_version>.jar.
  3. Copy this JAR file to the following directory: /TWS/JavaExt/eclipse/plugins/
  4. Remove the older version from the /TWS/JavaExt/eclipse/plugins/ directory to prevent conflicts.
  5. Restart theWebSphere Application Server Liberty on the master domain manager and the agent to initialize the updated plugin.
