摘　　要：分布式并行数据库系统以高可用性、高效率等特征愈来愈受到人们的关注。针对分布式并行数据库系统的特征,提出了分布式并行重定向算法,实现服务器节点的透明切换。该算法不仅能实现负载均衡以及位置透明性,提高系统效率,而且能保证节点故障时事务不被中断,实现系统的高可用性。Distributed parallel database system is increasingly concerned because of its characteristics, high-availability, high-efficiency and so on. Distributed redirection algorithm has been presented to accomplish the transparent switch of the node that a client has created connection with, according to the characteristics of the distributed parallel database system. The algorithm has not only accomplished system load balance and location transparency, and enhanced the system efficiency, but also ensured that the transaction don＇t be interrupted when the node fault occurred, and enhanced the system availability.

关 键 词：分布式并行数据库 分布式并行重定向 可周性 透明性
