还原点(Restore point)是Oracle10gR2配合Flashback database推出的一个新特性。Restore point可以单独使用,也可以和Flashback database联合使用。 我们知道,Flashback database提供了一种将数据库整个的回滚到之前某个时间点的功能,相当于使用之前的某个备份做基于时间点的恢复,但是比基于时间点的恢复更有效率,因为无需...
普通租户(Oracle 模式) SQL 语句 DDL CREATE RESTORE POINT 更新时间:2025-01-27 23:00:01 描述 该语句用来创建还原点(Restore Point)。使用该功能可以保留当前时刻的数据快照,之后可以基于此数据快照进行查询。目前还不支持将数据回滚到该还原点。 创建还原点后,该还原点的SCN值对应在V$RESTORE_POINT视图中SNAPSHO...
Restore pointsprovide capabilities related to Flashback Database and other media recoveryoperations. In particular, a guaranteed restore point created at an systemchange number (SCN) ensures that you can use Flashback Database to rewind thedatabase to this SCN. You can use restore points andFlash...
Flashback Database 和 restore points 都可以提供一个基于时间点的回滚,类似与RMAN 的 point-in-time recovery,但是这两种方法与RMAN 的区别是在恢复的速度上, 当我们在database upgrade 或者 快速创建测试环境的时候就可以使用这种技术,因为等我们升级遇到问题或者测试完成,还可以恢复我们之前的时间点。
