Abstract
An exclusive lock is acquired on each of an outer database ownership table and an inner database ownership table to obtain ownership of a database. The exclusive locks are converted to a pair of overlapping shared locks on each of the outer database ownership table and the inner database ownership table, where release and re-acquisition of each of the pair of overlapping shared locks on the outer database ownership table and the inner database ownership table permits database maintenance operations to be performed while maintaining the ownership of the database.
