1.在線修改

a.查一下表空間的當前位置

SQL> select TABLESPACE_NAME from dba_tablespaces;

b.修改要移動表空間的狀態為offline

SQL> alter tablespace SYSAUX offline;

c.os下把datafile? sysaux01.dbf'? 移到目標路徑 /data/ora_data01/INFA/ 下

d. 修改數據文件位置

SQL> alter tablespace SYSAUX rename datafile '/opt/oracle/oradata/INFA/sysaux01.dbf' to '/data/ora_data01/INFA/sysaux01.dbf';

e.修改表空間狀態為online

SQL> alter tablespace SYSAUX online;

f.檢查一下
SQL> select file_name from dba_data_files;

FILE_NAME
--------------------------------------------------------------------------------
/opt/oracle/oradata/INFA/system01.dbf
/data/ora_data01/INFA/sysaux01.dbf
/opt/oracle/oradata/INFA/undotbs01.dbf
/opt/oracle/oradata/INFA/users01.dbf
/data/ora_data01/SELADEVW/SELADEVW/infadom01.dbf
/data/ora_data01/SELADEVW/SELADEVW/infarep01.dbf

/data/ora_data01/SELADEVW/SELADEVW/dom0201.dbf

2.離線修改

a.shutdown 數據庫

shutdown immediate;

b.使用系統命令copy 數據文件到目標位置

c.啟動數據庫到mount狀態,

startup mount;

d.更改數據文件位置

alter database rename file?
'/opt/oracle/oradata/DAC/system01.dbf',
'/opt/oracle/oradata/DAC/sysaux01.dbf',
'/opt/oracle/oradata/DAC/undotbs01.dbf',
'/opt/oracle/oradata/DAC/users01.dbf',
'/data/ora_data01/SELADEVW/SELADEVW/dac01.dbf' to
'/data/ora_data01/DAC/system01.dbf',
'/data/ora_data01/DAC/sysaux01.dbf',
'/data/ora_data01/DAC/undotbs01.dbf',
'/data/ora_data01/DAC/users01.dbf',
'/data/ora_data01/DAC/dac01.dbf';

e.打開數據庫
SQL> alter database open;

Database altered.
f.檢查一下 OK
SQL> select name from v$datafile;

NAME
--------------------------------------------------------------------------------
/data/ora_data01/DAC/system01.dbf
/data/ora_data01/DAC/sysaux01.dbf
/data/ora_data01/DAC/undotbs01.dbf
/data/ora_data01/DAC/users01.dbf
/data/ora_data01/DAC/dac01.dbf
