摘要
三峡水调自动化系统和成都水调自动化系统采用GoldenGate实现了数据库单向复制,解决了双服务中心构架底层数据单向同步问题。对数据库复制的概念、主流技术、技术选择进行了阐述和分析,对数据库单向复制的应用实施方案进行了详细阐述,并对关键技术和难点进行了分析。方案目前已成功实施,对试验结果和运行情况进行了介绍和分析。
Database unidirectional replication based on the GoldenGate technology is already built between Hydropower Dispatching Automation Systems of Three Gorge and Chengdu. This paper describes the method of choice of database unidirectional replication technology, introduces the solution of implementation from Three Gorges to Chengdu and analyzes the key technologies and difficulties. This article also introduces and analyzes the results of tests and operations of database unidirectional replication from Three Gorges to Chengdu.
