一.RMAN 完全恢复

完全恢复是指当数据文件出现介质失败时,使用RESTORE命令转储备份(到原存放地或可用的设备),然后再使用RECOVER命令将数据文件恢复到失败点的状态。

SYSTEM表空间数据文件恢复要求数据库必须在mount状态进行,其他数据文件恢复既可以使数据库在mount状态,也可以是open状态进行;

当需要恢复所有数据文件或者要求在数据库级别恢复时,应该使用完全恢复,这时数据库需启动到mount状态;恢复至原存放地脚本如下(在open状态下运行此脚本):

 

RMAN> run{
2> startup force mount
3> restore database;
4> recover database;
5> alter database open;
6> }
