摘要
该文设计并实现了一种Oracle数据库容灾系统,支持多种容灾策略,并具有远程数据复制功能,可实时地将数据及相关操作复制到远程备用数据库,保证两边数据的一致性。当本地主数据库发生灾难时,可迅速将数据库服务漂移到远程备用数据库上,保证了服务的连续性,同时可利用备份数据对本地主数据库进行恢复,从而达到了Oracle数据库容灾的目的。
A Oracle Database Disaster Tolerance System is designed and implemented, supPorting multi-policy and remote data replication which means replicating real-time data and correlative manipulations to remote standby database to keep data consistency between the local and the remote, when disaster happens to local primary database, service can be drifted from the local to the remote swiftly so that the continuity of service is kept. At the same time, local primary database can also be recovered by data backup. So, the target of Oracle database disaster tolerance can be properly achieved.
