ORA-01113: file xxxx needs media recovery

由於規范存儲位置以及存儲空間調整緣故需要移動表空間MRP_INDEX2的數據文件，如下所示，首先將表空間MRP_INDEX2脫機; 然后復制數據文件；接着重命名數據文件，最后將表空間MRP_INDEX2聯機.

在操作過后，最后一步將表空間MRP_INDEX2聯機上線時，出現了意外錯誤信息,如下所示：

SQL> ALTER TABLESPACE MRP_INDEX2 OFFLINE NORMAL;

Tablespace altered.

SQL> !cp /u03/flash_recovery_area/oradata/epps/mrp_index2_x01.dbf  /u04/epps/oradata/mrp_index2_x01.dbf
SQL> !cp /u03/flash_recovery_area/oradata/epps/mrp_index2_x02.dbf  /u04/epps/oradata/mrp_index2_x02.dbf

SQL> ALTER DATABASE RENAME FILE '/u03/flash_recovery_area/oradata/epps/mrp_index2_x01.dbf' TO '/u04/epps/oradata/mrp_index2_x01.dbf';


Database altered.

如下所示，在重命名文件時，其中一個文件路徑'u04/epps/oradata/mrp_index2_x02.dbf'弄錯了，當時一直沒有留意到這個錯誤，怕耽擱Tablespace的聯機上線時間。於是先將表空間MRP_INDEX2聯機上線

SQL> ALTER DATABASE RENAME FILE '/u03/flash_recovery_area/oradata/epps/mrp_index2_x02.dbf' TO 'u04/epps/oradata/mrp_index2_x02.dbf'

檢查過后發現了上面腳本錯誤，於是接着處理，但是將表空間MRP_INDEX2脫機后，沒有重新拷貝數據文件過去，直接重命名數據文件（SCN已經改變，導致下面ORA-01113錯誤），然后表空間聯機上線時，出現了下面錯誤

SQL> ALTER TABLESPACE MRP_INDEX2 OFFLINE NORMAL;

Tablespace altered.

SQL> ALTER DATABASE RENAME FILE '/u03/flash_recovery_area/oradata/epps/mrp_index2_x02.dbf' TO '/u04/epps/oradata/mrp_index2_x02.dbf';

Database altered.

SQL> ALTER TABLESPACE MRP_INDEX2 ONLINE ;

ORA-01110: data file 86: '/u04/epps/oradata/mrp_index2_x02.dbf'

 

解決方法：

1：首先將對應報錯的數據文件脫機

SQL> alter database datafile '/u04/epps/oradata/mrp_index2_x02.dbf' offline;

Database altered.

2：其次recover這個數據文件

SQL> alter database recover datafile '/u04/epps/oradata/mrp_index2_x02.dbf';

Database altered.

3：然后將該數據文件聯機上線

SQL> alter database datafile '/u04/epps/oradata/mrp_index2_x02.dbf' online;

Database altered.

4：最后將該表空間MRP_INDEX2聯機上線。

SQL> ALTER TABLESPACE MRP_INDEX2 ONLINE ;

當然也可以使用RMAN還原，這里感覺使用SQL命令還原要簡單方便一點，最后刪除拷貝前的文件

rm /u03/flash_recovery_area/oradata/epps/mrp_index2_x01.dbf

rm /u03/flash_recovery_area/oradata/epps/mrp_index2_x02.dbf
