墨墨导读：通过历史控制文件恢复数据库，只需这10步。
1. 记录控制文件、数据文件头的scn
SYS@enmo>select checkpoint_change# from v$database;CHECKPOINT_CHANGE#
------------------18502624SYS@enmo>select name,checkpoint_change# from v$datafile;NAME CHECKPOINT_CHANGE#
-------------------------------------------------- ------------------

/u01/app/dbfile/reccat.dbf8 rows selected.
2. 关闭数据库并移动控制文件
SYS@enmo>shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.[oracle@ora:enmo enmo]$mv control01.ctl control01.ctl.bak
[oracle@ora:enmo enmo]$mv control02.ctl control02.ctl.bak
3. 开启数据库到nomount;
SYS@enmo>startup nomount;
ORACLE instance started.Total System Global Area 1048576000 bytes
Fixed Size 8628640 bytes
Variable Size 796919392 bytes
Database Buffers 234881024 bytes
Redo Buffers 8146944 bytes
SYS@enmo>select status from v$instance;STATUS
------------------------------------
STARTED
4. 使用rman恢复历史备份的控制文件
RMAN> restore controlfile from autobackup;Starting restore at 2020-03-13 12:51:11 allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=10 device type=DISKrecovery area destination: /u01/app/fra

output file name=/u01/app/dbfile/enmo/control01.ctl
output file name=/u01/app/dbfile/enmo/control02.ctl
Finished restore at 2020-03-13 12:51:13
5. 更新数据库到mount
SYS@enmo>alter database mount;Database altered.
6. 查看控制文件和数据文件中的scn号
--可以看到数据文件头中记录的scn(18504054)大于控制文件中记录的scn(18261588)SYS@enmo>set line 999
SYS@enmo>col name for a50

7. 更新数据库为open
SYS@enmo>alter database open;
alter database open
