摘　　要：传统的两阶段提交协议在分布式数据库管理系统的事务处理中得到广泛运用,较好地保证了分布事务的一致性和数据的一致性。然而,这个协议会出现阻塞问题,严重影响系统资源的利用率。针对这个弱点从事务的分类处理、快照技术、通信结构、终结协议等方面进行探讨,提出五种解决方案,并且分析了这些方案的适用场合。The traditional two-phase commitment protocol is widely applied in the transaction disposal of Distributed Database Management System. It assures the consistency of distributed transactions and data. However, this protocol may cause blocking problem, It will badly influence the using efficiency of system resources. This paper aims at that weakness and discusses on these aspects, such as transaction＇s sorting disposal, snapshot technology, communication structure ,finality protocol and so on. It puts forward five solutions to the problem and analyses their own applied occasions.
