Real-Time Distributed Data Base Locking Manager.

Abstract

A method of data sharing between processors on the same network utilizes token migration for providing a data locking mechanism. A token migrates between the processors for each original data item and its replicas. Only the processor having possession of the token can perform certain operations such as updating and transmitting this updated information to the other processors. Two different queuing arrangements are described for giving up or retaining possession of the token when a processor, not in possession of the token makes a request for the token.
