ABSTRACT:
An automated method is provided of replicating a locking protocol in a database environment for performing I/O operations wherein the database environment includes a plurality of databases. A locking protocol is performed that includes one or more explicit locking operations on objects in a first database of the database environment. The one or more explicit locking operations are replicated in one or more other databases in the database environment. At least some of the explicit locking operations are performed asynchronously with respect to the explicit locking operations performed in the first database. I/O operations are performed at the first database of the database environment that are associated with the one or more explicit locking operations implemented in the first database.
