  org.jivesoftware.openfire.muc.spi.MUCPersistenceManager

public class MUCPersistenceManager
extends Object

A manager responsible for ensuring room persistence. There are different ways to make a room persistent. The first attempt will be to save the room in a relation database. If for some reason the room can't be saved in the database an alternative repository will be used to save the room such as XML files.

After the problem with the database has been solved, the information saved in the XML files will be moved to the database.
