Perform the following steps to apply the hotfix:

  1. Stop Appian. See Starting and Stopping Appian for detailed instructions:
    1. Shut down the application server.
    2. Shut down the search server.
    3. Shut down the data server.
    4. Shutdown all Appian Engines, ensuring that the engines are checkpointed upon shutdown.
  2. Back up your existing Appian instance. See Backing Up Your Existing Appian Instance.
  3. Unzip the contents of the archive into your <APPIAN_HOME> directory.
  4. Run the deleteFiles script (deleteFiles.bat on Windows, on Linux) that is now located in your <APPIAN_HOME> directory.
    • If the script reports that some files were not deleted, address the reason for the failure (common causes listed below), and run it again until it no longer reports failed deletions.
    • Common causes of failed file deletion include:
    • The file is open in another window or process
    • The file is locked
    • You do not have permission to delete the file
  5. Unzip the contents of the archive that is now located your <APPIAN_HOME> directory.
  6. Run the installJdk script (installJdk.bat on Windows, on Linux).
  7. If you maintain customized or overridden Spring Security .xml files, merge them with the associated base files in the /deployment/web.war/WEB-INF/conf/security/ directory.
  8. Delete the deleteFiles scripts, the installJdk scripts, the OpenJDK .tar.gz and .zip files, and
  9. If you are using a Web server, copy the content of <APPIAN_HOME>/deployment/web.war to the folder where the Web server is getting the static resources. See Copy Static Resources to the Web Server for more information.
  10. Run the configure script to deploy your environment's configuration and re-configure any node names previously set by the configure script tools.
  11. Start Appian:
    1. Start the Appian Engines.
    2. Start the data server.
    3. Start the search server.
