• 論文抄録 / 内容記述: In object-based systems objects are replicated to increase performance reliability and availability. We discuss a novel object-based locking（OBL）protocol for locking replicas of objects that support abstract methods; this protocol was created by extending the quorum-based protocol to abstract objects. Here the number of the replicas locked is decided on the basis of the frequency of use of the lock mode. Unless two methods conflict subsets of the replicas locked by the methods do not intersect even if the methods change the replicas. Methods not computed on a replica but on another one are computed when a method conflicting with them issued to the replica. Hence the replicas have the same state. We propose a version vector for identifying what methods are computed on a replica.
