Uninstalling interim fixes from the IBM Engineering Lifecycle Management server

Uninstalling the server includes removing the contents of server from the specific directory and rolling back to the backed up version.

1. Stop the Engineering Lifecycle Management server.
2. Take a back up and then remove the contents of the following directory <server_installation_directory>/server/patch.
3. Clear the application server cache. For instructions on clearing the cache, see the documentation of the application server. To clear the application and class cache on WebSphere Application Server, complete the following steps:
   1. Remove the contents from these directories under the profile root. For example: <WAS_HOME>/<AppServer>/profiles/<Profile>, except for the noted help directory: temp, wstemp, workspace.
      Note: Do not remove this directory, which is required for the ELM local help: temp/{jts_node}/{jts_server}/clmhelp_war.
   2. For UNIX platforms, run the following script: <WebSphere_HOME>/bin/clearClassCache.sh
   3. For Windows platforms, run the following script: <WebSphere_HOME>\bin\clearClassCache.bat
4. Start the Engineering Lifecycle Management server.
5. Run repotools-<app> -clean for each application that is installed.
   • - repotools-ccm -clean
   • - repotools-gc -clean
   • - repotools-jts -clean
   • - repotools-qm -clean
   • - repotools-relm -clean
   • - repotools-rm -clean
   • - repotools-dcc -clean
6. To validate that the server is successfully installed or uninstalled, complete the following steps:
   • After the server starts, open an Engineering Lifecycle Management application.
   • Click Help > About the Server.
   • In the Build Information section, review the interim fix information to confirm that it is either installed or uninstalled.
