1 首先備份測試資料檔案

RMAN> backup datafile 5;

Starting backup at 06-NOV-14
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=43 device type=DISK
channel ORA_DISK_1: starting full datafile backup set
channel ORA_DISK_1: specifying datafile(s) in backup set
input datafile file number=00005 name=/data/oracle/oradata/aaron/example01.dbf
channel ORA_DISK_1: starting piece 1 at 06-NOV-14
channel ORA_DISK_1: finished piece 1 at 06-NOV-14
piece handle=/data/oracle/flash_recovery_area/AARON/backupset/2014_11_06/o1_mf_nnndf_TAG20141106T001531_b5pck41v_.bkp tag=TAG20141106T001531 comment=NONE
channel ORA_DISK_1: backup set complete, elapsed time: 00:00:16
Finished backup at 06-NOV-14

Starting Control File and SPFILE Autobackup at 06-NOV-14
piece handle=/data/oracle/flash_recovery_area/AARON/autobackup/2014_11_06/o1_mf_s_862877747_b5pcknj2_.bkp comment=NONE
Finished Control File and SPFILE Autobackup at 06-NOV-14

2 刪除測試資料檔案

SYS@aaron> !rm /data/oracle/oradata/aaron/example01.dbf

3 重新啟動資料庫檢視錯誤資訊

SYS@aaron> shutdown abort
ORACLE instance shut down.
SYS@aaron> startup

4 重新連線RMAN 並執行 List Failure

RMAN> list failure;

using target database control file instead of recovery catalog
List of Database Failures
=========================

Failure ID Priority Status    Time Detected Summary

5 檢視建議指令碼

RMAN> advise failure;

6 執行恢復操作

RMAN> restore datafile 5;
