基于事务的分布式数据库复制服务器技术

Duplicate Server Technology Based on Transaction of Distrabuted Database Server

在大规模的分布式数据库系统中，数据库复制器对于系统的可靠性、系统的效率等起着非常关键的作用。对基于事务的分布式数据库复制服务器技术作了深入分析，从复制结构、复制方式故障分析等方面系统地阐述了其技术原理和特点，并从可用性、数据传输的一致性、场地自治等方面充分地论证了这一技术的先进性和实用性。

In the large scale distrabuted database system, duplicate database server affects the system efficiecy and system reliability.This paper deaply discusses the duplicate server technology based on transaction of distrabuted database server. The paper makes a systematic exposition of duplicate architecture, duplicate method and failure recovery. Final, the advanced and practical technology is fully proved in feasibility, consistency of data transfer and site autonomy.
