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';

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 channel ORA_DISK_1: starting piece 1 at 2009-12-16 22:34:31 channel ORA_DISK_1: finished piece 1 at 2009-12-16 22:34:32 piece handle=/oracle/app/oracle/flash_recovery_area/SECOOLER/backupset/2009_12_16/o1_mf_ncnnf_TAG20091216T223431_5lkvzqp6_.bkp tag=TAG20091216T223431 comment=NONE channel ORA_DISK_1: backup set complete, elapsed time: 00:00:01 Finished backup at 2009-12-16 22:34:32

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 channel ORA_DISK_1: starting datafile copy copying current control file output filename=/orabackup/rman_copy_controlfile.ctl tag=TAG20091216T224247 recid=1 stamp=705796967 channel ORA_DISK_1: datafile copy complete, elapsed time: 00:00:01 Finished backup at 2009-12-16 22:42:48
