摘要

提出了一种适用于异构多数据库系统的集成并发控制与恢复方法。参与者的两阶段本地承诺和准备状态恢复的责任由一个名为2PC Agent的实体接管。该方法的主要重要性在于在存在某一类与参与者相关的故障时保持全局序列化性。提出了相关的恢复方法，包括一种新的故障时间乐观并发控制方法。

2PC Agent method: achieving serializability in presence of failures in a heterogeneous multidatabase

A method for integrated concurrency control and recovery, applicable to heterogeneous multidatabase systems, is proposed. The responsibility for two-phase local commitment and recovery of the prepared state at participants is taken over by an entity called 2PC Agent. The main importance of the method is in preserving global serializability in the presence of a certain class of participant-related failures. The related recovery methods, including a novel failure-time optimistic concurrency control method, are presented.<>
