ABSTRACT:
A method is provided to verify a database copy of a primary database which has been replicated. A secondary physically consistent copy of the primary database is put in a state of quiesce while the primary database is allowed to resume update activity. The consistent copy, in a state of quiesce, can be used for database maintenance activities or as a recovery source should the primary database be damaged, but the consistent copy is first checked for integrity by using a Verify option before such recovery source is utilized.
