有时候我们想把数据文件移动到其他的目录下，可以按照如下操作：

• 查看数据文件位置
  

SQL>  select file_name from sys.dba_data_files;
FILE_NAME--------------------------------------------------------------------------------
/home/app/oracle/oradata/sztech/users01.dbf
/home/app/oracle/oradata/sztech/undotbs01.dbf
/home/app/oracle/oradata/sztech/sysaux01.dbf
/home/app/oracle/oradata/sztech/system01.dbf


  2.关机并启动到mount状态
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.

SQL> startup mount;
ORACLE instance started.
Total System Global Area 2.1379E+10 bytes
Fixed Size                    2262656 bytes
Variable Size                 1677724032 bytes
Database Buffers         1.9663E+10 bytes
Redo Buffers                   36073472 bytes
Database mounted.

3.执行修改
SQL> alter database rename file   '/home/app/oracle/oradata/sztech/users01.dbf'   to   '/u01/app/oradata/sztech/users01.dbf';
Database altered.
SQL> alter database rename file   '/home/app/oracle/oradata/sztech/undotbs01.dbf'   to   '/u01/app/oradata/sztech/undotbs01.dbf';
Database altered.
SQL> alter database rename file   '/home/app/oracle/oradata/sztech/sysaux01.dbf'   to   '/u01/app/oradata/sztech/sysaux01.dbf';
Database altered.
SQL> alter database rename file   '/home/app/oracle/oradata/sztech/system01.dbf'   to   '/u01/app/oradata/sztech/system01.dbf';
Database altered.

4.启动数据库
SQL> alter database open;
Database altered.
