An Enterprise Server Data Management System provides for the handling of large data objects (LOB) according to the data size required for the large object. Methods are provided to find a particular object that is stored or to delete such an object.

System and method to manipulate large objects on enterprise server data management system

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.
