1. A method for managing access to a particular resource, the method comprising the steps of:

  • receiving a request for a lock on the particular resource from a first process residing on a first node;

    wherein the first process makes a change to the particular resource prior to knowing whether the duplicate lock data has been generated;

    generating on a second node lock data that indicates that a lock on the particular resource has been granted to the first process;

    generating duplicate lock data on a third node that indicates that the lock on the particular resource has been granted to the first process; and

    providing an acknowledge message to the first process to indicate that the duplicate lock data has been generated and that a change made to the particular resource by the first process can be made permanent.
