RMAN恢復案例:丟失非系統資料檔案恢復
一、資料庫執行過程中丟失一個資料檔案恢復
1、模擬介質損壞:
SQL> host rm /u01/oracle/oradata/XUE/users01.dbf[@more@]
2、建立測試表驗證介質損壞:
SQL> create table t tablespace users as select * from all_objects;
create table t tablespace users as select * from all_objects
*
ERROR at line 1:
ORA-01116: error in opening database file 4
ORA-01110: data file 4: '/u01/oracle/oradata/XUE/users01.dbf'
ORA-27041: unable to open file
Linux Error: 2: No such file or directory
Additional information: 3
3、將表空間離線、檢視資料檔案狀態:
SQL> alter tablespace users offline ;
Tablespace altered.
SQL> select name,status,enabled from v$datafile;
NAME STATUS ENABLED
---------------------------------------- ------- ----------
/u01/oracle/oradata/XUE/system01.dbf SYSTEM READ WRITE
/u01/oracle/oradata/XUE/undotbs01.dbf ONLINE READ WRITE
/u01/oracle/oradata/XUE/indx01.dbf ONLINE READ WRITE
/u01/oracle/oradata/XUE/users01.dbf OFFLINE DISABLED
SQL> alter tablespace users online;
alter tablespace users online
*
ERROR at line 1:
ORA-01157: cannot identify/lock data file 4 - see DBWR trace file
ORA-01110: data file 4: '/u01/oracle/oradata/XUE/users01.dbf'
4、檢視恢復檔案資訊:
SQL> select * from v$recover_file;
FILE# ONLINE ONLINE_
---------- ------- -------
ERROR CHANGE#

Copyright (c) 1995, 2002, Oracle Corporation. All rights reserved.
connected to target database: XUE (DBID=285819149)
5、執行命令恢復表空間:
RMAN> run {
2> allocate channel c1 type disk;
3> restore tablespace users;
4> recover tablespace users;
5> sql 'alter tablespace users online';
6> release channel c1;
7> }
allocated channel: c1
channel c1: sid=16 devtype=DISK
Starting restore at 05-JAN-05
channel c1: starting datafile backupset restore
channel c1: specifying datafile(s) to restore from backup set
restoring datafile 00004 to /u01/oracle/oradata/XUE/users01.dbf
channel c1: restored backup piece 1
piece handle=/opt/rman_backup/df_546708956_8_1 tag=TAG20050104T153556 params=NULL
channel c1: restore complete
Finished restore at 05-JAN-05
Starting recover at 05-JAN-05
starting media recovery
archive log thread 1 sequence 66 is already on disk as file /u01/oracle/oradata/XUE/archive/66.arc
archive log thread 1 sequence 67 is already on disk as file /u01/oracle/oradata/XUE/archive/67.arc
archive log thread 1 sequence 68 is already on disk as file /u01/oracle/oradata/XUE/archive/68.arc

media recovery complete
Finished recover at 05-JAN-05
sql statement: alter tablespace users online
released channel: c1
RMAN> exit
Recovery Manager complete.
6、驗證恢復成功:
SQL> select name,status,enabled from v$datafile;
NAME STATUS ENABLED
---------------------------------------- ------- ----------
/u01/oracle/oradata/XUE/system01.dbf SYSTEM READ WRITE
/u01/oracle/oradata/XUE/undotbs01.dbf ONLINE READ WRITE
/u01/oracle/oradata/XUE/indx01.dbf ONLINE READ WRITE
/u01/oracle/oradata/XUE/users01.dbf ONLINE READ WRITE
SQL> create table t tablespace users as select * from all_objects;
Table created.
SQL> select count(*) from t;
COUNT(*)
