titleUsing different update strategies

The steps described below will update the program files by overwriting the previous installation. Some administrators however like to move the existing installation to a backup directory, extract the tarball to the previous location and run that instead. You can also go with that procedure, however please take care of the the following things:

  • External database users: Make sure you still have the /libs sub-directory with the database drive driver in it residing in the directory with the and PowerFolder-Server.jar files, otherwise the server will fail to start because of the missing database driver. If the database driver is missing a typical log messages looks like this: "APPARENT DEADLOCK!!! Creating emergency threads for unassigned pending tasks!" und "java.sql.SQLException: No suitable driver"
  • Startup script changes: Please adapt all changes you did to the previous startup script (most likely SERVER_INSTALLSERVER_HOME or JAVA_MEM) also to the one extracted from the new package.
