  Abstract

In this paper, a new locking protocol which can increase the concurrency in an Object Oriented Database System is proposed. The proposed locking protocol uses the Root object identifier to identify the root of a component object in a composite object. The transaction that requests a lock on the component object checks whether Rid of the component object has been locked by another transaction. Even though the class of the component object is locked by one transaction, other transactions can concurrently access other instances in the class, if each Rid of them is not locked by any other transaction. This can increase the degree of concurrency.
