3.关闭数据库，删除数据文件，然后使用备份恢复数据库。

3.1关闭数据库

RMAN> shutdown immediate;

database closed

database dismounted

Oracle instance shut down

3.2.删除数据文件：

[oracle@CS-SI-DG01 orcl]$ cd /oradata/

[oracle@CS-SI-DG01 oradata]$ ls

arch backup matrix ogg orcl orcl1 rman

[oracle@CS-SI-DG01 oradata]$ cd orcl

orcl/ orcl1/

[oracle@CS-SI-DG01 oradata]$ cd orcl

[oracle@CS-SI-DG01 orcl]$ ls

control01.ctl redo02.log system01.dbf tbspart04.dbf test2.dbf users01.dbf

control02.ctl redo03.log tbspart01.dbf temp01.dbf tom01.dbf

linktbs01.dbf rman01.dbf tbspart02.dbf test01.dbf tom09.dbf

[oracle@CS-SI-DG01 orcl]$ rm *

[oracle@CS-SI-DG01 orcl]$

3.3.启动数据库到mount状态：

RMAN> startup nomount;

Oracle instance started

Fixed Size 2229824 bytes

Variable Size 385878464 bytes

Database Buffers 113246208 bytes

Redo Buffers 8056832 bytes

3.4.从之前的备份中恢复控制文件：

RMAN> restore controlfile from '/u2/oracle/fast_recovery_area/ORCL/autobackup/2015_12_24/o1_mf_s_899282073_c7phdsrq_.bkp';

Starting restore at 24-DEC-15

output file name=/oradata/orcl/control01.ctl

output file name=/oradata/orcl/control02.ctl

Finished restore at 24-DEC-15

3.5.将数据启动到mount状态：

RMAN> alter database mount;

database mounted

released channel: ORA_DISK_1

3.6.还原数据库：

RMAN> restore database;

Starting restore at 24-DEC-15

Starting implicit crosscheck backup at 24-DEC-15

3.7.resetlogs方式打开数据库：

RMAN> alter database open resetlogs;

database opened

3.8.查看对应物（此时相比之前又产生了一个对应物）：

RMAN> list incarnation;

4.恢复对应物6：

4.1.关闭数据，然后启动到mount状态：

[oracle@CS-SI-DG01 ~]$ rman target /
