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
ORA-01113: file xxxx needs media recovery
