千家信息网最后更新 2025年12月03日【备份】RMAN中对控制文件的几种备份方法控制文件对于Oracle数据库来说是至关重要的，这里简单的介绍几种在RMAN中对控制文件的备份方法。
1.进入RMAN命令行界面
secooler@secDB /oracle/oradata$ rman target /
Recovery Manager: Release 10.2.0.3.0 - Production on Wed Dec 16 16:39:15 2009
Copyright (c) 1982, 2005, Oracle. All rights reserved.
connected to target database: SECOOLER (DBID=21803462)
RMAN>
2.修改控制文件备份方式为自动备份
RMAN> configure controlfile autobackup on;
new RMAN configuration parameters:
CONFIGURE CONTROLFILE AUTOBACKUP ON;
new RMAN configuration parameters are successfully stored
3.确认参数是否修改成功，成功。
RMAN> show CONTROLFILE AUTOBACKUP;
RMAN configuration parameters are:
CONFIGURE CONTROLFILE AUTOBACKUP ON;
4.修改控制文件的备份文件的存放位置，这里注意一下其中的"%F"不可或缺。
RMAN> configure controlfile autobackup format for device type disk to '/orabackup/%F';
new RMAN configuration parameters:
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/orabackup/%F';
new RMAN configuration parameters are successfully stored
5.确认一下备份文件备份位置参数是否修改成功。成功。
RMAN> show controlfile autobackup format;
RMAN configuration parameters are:
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/orabackup/%F';
6.此时使用"backup database"命令可以出发控制文件的备份
RMAN> backup database;
Starting backup at 2009-12-16 16:54:21
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=146 devtype=DISK
channel ORA_DISK_1: starting full datafile backupset
channel ORA_DISK_1: specifying datafile(s) in backupset

7.在RMAN中使用"backup current controlfile"亦可完成控制文件的备份。
RMAN> backup current controlfile;
Starting backup at 2009-12-16 22:34:31
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: sid=141 devtype=DISK
channel ORA_DISK_1: starting full datafile backupset
channel ORA_DISK_1: specifying datafile(s) in backupset
including current control file in backupset

Finished Control File and SPFILE Autobackup at 2009-12-16 22:34:33
8.在RMAN中得到曾经备份过的控制文件信息
RMAN> list backup of controlfile;

9.使用RMAN的copy命令亦完成可对控制文件的备份任务
RMAN> copy current controlfile to '/orabackup/rman_copy_controlfile.ctl';
Starting backup at 2009-12-16 22:42:47
using channel ORA_DISK_1

10.小结
以上仅是罗列了几种在RMAN中备份控制文件的方法，途径很多，适用就好，具体环境下使用顺手的备份方法便可。诚然，备份的根本目的是为恢复，任何一种备份方法在紧要关头只要可用便是王道。
Good luck.
