OpenFire database table and associated field that denotes a persisted room.

       I would like to know if anyone knows what OpenFire database table and associated field that denotes if a room is persisted or not.    I need to load test my OpenFire development environment and I have a .NET Windows Form application using Jabber-Net to remove all created rooms for my OpenFire domain and service; this could potentially be up to 5K rooms if not more.  Unfortunately it does not appear I can programmatically remove persisted rooms so one idea I had is a could update the database and revert this "flag" and the perform the room removals with this application.
