For traceability reasons data about all user sessions (open and closed) is stored permanently by the Application Server. If the user has no special permission he can only list his own user sessions. Users with the system permission Read all user sessions can also list sessions of other users.

Since the session log might get huge over time the Application Server provides the possibility to purge the user session log. Purging will delete all closed sessions from the session log that were closed before a given timestamp. Purging the session log can be triggered by users with the system permission Purge user session log (18).
