摘要
Golden Gate和Active DataGuard都是Oracle公司的产品,Golden Gate能够实现与生产数据库亚秒级的数据同步,同时可实现两端数据的同时写入;Active DataGuard技术不仅仅能够实现数据的实时同步,还能够提供实时的数据查询和报表业务等。因此,将Golden Gate和Active DataGuard技术结合不仅能够实现生产数据的容灾,还能够实现灾备端数据库读写分离,提高系统整体的业务处理能力,同时充分利用备份端的计算能力,减少投入成本。
Golden Gate and Active Data Guard are both products of Oracle. Golden Gate can realize data synchronization with production database at the second level,and the same time it can realize writing data on both ends at the same time. Active Data Guard not only can realize the data real-time synchronization,also can provide real-time data query and report. Therefore, to combine Golden Gate and Active Data Guard technology not only can realize the disaster of the production data,but also can realize reading and writing separation of backend database and it improves the business processing ability of the system as a whole. At the same time it can make full use of the computing power of the backend resources to reduce the cost.
