ORA-01113: file xxxx needs media recovery

由于规范存储位置以及存储空间调整缘故需要移动表空间MRP_INDEX2的数据文件，如下所示，首先将表空间MRP_INDEX2脱机; 然后复制数据文件；接着重命名数据文件，最后将表空间MRP_INDEX2联机.

在操作过后，最后一步将表空间MRP_INDEX2联机上线时，出现了意外错误信息,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，在重命名文件时，其中一个文件路径'u04/epps/oradata/mrp_index2_x02.dbf'弄错了，当时一直没有留意到这个错误，怕耽搁Tablespace的联机上线时间。于是先将表空间MRP_INDEX2联机上线

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

检查过后发现了上面脚本错误，于是接着处理，但是将表空间MRP_INDEX2脱机后，没有重新拷贝数据文件过去，直接重命名数据文件（SCN已经改变，导致下面ORA-01113错误），然后表空间联机上线时，出现了下面错误

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';

ERROR at line 1:

ORA-01113: file 86 needs media recovery

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

解决方法：

1：首先将对应报错的数据文件脱机

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

Database altered.

2：其次recover这个数据文件

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

Database altered.

3：然后将该数据文件联机上线

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

Database altered.

4：最后将该表空间MRP_INDEX2联机上线。

SQL> ALTER TABLESPACE MRP_INDEX2 ONLINE ;

当然也可以使用RMAN还原，这里感觉使用SQL命令还原要简单方便一点，最后删除拷贝前的文件

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

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