基于分布式数据库系统的故障恢复技术研究

The study on the data restoration technology of distributed database system

本文在对分布式数据库系统探讨的基础上,基于备份和日志记录技术,提出了一种基于两阶段提交协议的分布式数据库系统的数据恢复方法。该方法基本能实现分布式事务执行的无阻塞,在正确的实现分布式数据库恢复的前提下,保证了分布式数据库系统的高可用性。

Based on the deep-going exploration of the distributed database system,the backup and the log-file technology,this article puts forwards a data restoration method on the basis of two-phase commit protocol.This method can basically realize the distributed transaction execution without any block.Besides the correct realization of the distributed database restoration,this method guarantees the high usability of the distributed database system.
