ABSTRACT:
Lock management in a distributed data sharing computer system in which resources are shared by servers having local lock managers and the computer system having a global lock manager. Lock modes are defined to govern the availability of resources to the servers, including defining at least one lock mode that conflicts with at least another of the lock modes without covering any locks associated with the lock modes. Locks indicative of a specific lock mode are assigned to the resources. Requests for access to the resources are administered by a local lock manager associated with the requesting server without exposing the lock modes associated with the locks on the resources to the global lock manager unless the requests for access relate to a resource that is not covered by a lock assigned by the global lock manager.
