ABSTRACT:
In a distributed file system having a plurality of file servers each associated with a plurality of workstations having cache memories, data locks granted by the file servers to the workstations have variable lock lifetimes that are selected based on system parameters. The parameters selected to determine lock lifetimes can be either statically determined, in which case system operating parameters such as read/write ratio for data objects are assumed, or can be dynamically determined, in which case real-time system operating parameters such as current read/write ratios are used to determine the appropriate lock lifetime.
