Method and apparatus for coordinating access to a shared object amongst a plurality of processes in a distributed system. One process is identified as a lock owner process controlling a lock associated with the shared object. When a process needs to access the shared object, it requests control of the lock from the lock owner process. When no other process controls the lock, the lock owner process grants control to the requesting process. When another process controls the lock, the lock owner process places the requesting process in a queue and waits for the lock to become available. All accesses to the shared object are processed through the lock owner processes thus assuring coordination and synchronization among the processes.
