有時候我們想把數據文件移動到其他的目錄下，可以按照如下操作：

查看數據文件位置

SQL>??select?file_name?from?sys.dba_data_files;

FILE_NAME

--------------------------------------------------------------------------------

/home/app/oracle/oradata/orahq/users01.dbf

/home/app/oracle/oradata/orahq/undotbs01.dbf

/home/app/oracle/oradata/orahq/sysaux01.dbf

/home/app/oracle/oradata/orahq/system01.dbf

2.關機并啟動到mount狀態

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.執行修改

SQL>?alter?database?rename?file???'/home/app/oracle/oradata/orahq/users01.dbf'???to???'/alidata1/oradata/orahq/users01.dbf';

Database?altered.

SQL>?alter?database?rename?file???'/home/app/oracle/oradata/orahq/undotbs01.dbf'???to???'/alidata1/oradata/orahq/undotbs01.dbf';

Database?altered.

SQL>?alter?database?rename?file???'/home/app/oracle/oradata/orahq/sysaux01.dbf'???to???'/alidata1/oradata/orahq/sysaux01.dbf';

Database?altered.

SQL>?alter?database?rename?file???'/home/app/oracle/oradata/orahq/system01.dbf'???to???'/alidata1/oradata/orahq/system01.dbf';
