一、停庫修改數據文件目錄、文件名
1、當前數據文件目錄
SQL> select tablespace_name,file_name from dba_data_files;
TABLESPACE_NAME FILE_NAME
--------------- --------------------------------------------------
PAR /u01/app/oracle/oradata/orcl/par01.dbf
TEST /u01/app/oracle/oradata/orcl/test01.dbf
USERS /u01/app/oracle/oradata/orcl/users01.dbf
UNDOTBS1 /u01/app/oracle/oradata/orcl/undotbs01.dbf
SYSAUX /u01/app/oracle/oradata/orcl/sysaux01.dbf
SYSTEM /u01/app/oracle/oradata/orcl/system01.dbf
TT /u01/app/oracle/tt.dbf
2、停庫
SQL> shutdown immediate
Database closed.
Database dismounted.
ORACLE instance shut down.
3、啟動到mount狀態
SQL> startup mount
ORACLE instance started.
Total System Global Area 939495424 bytes
Fixed Size 2258840 bytes
Variable Size 301992040 bytes
Database Buffers 629145600 bytes
Redo Buffers 6098944 bytes
Database mounted.
4、拷貝數據文件
cp /u01/app/oracle/tt.dbf /u01/app/oracle/oradata/orcl/tt01.dbf
5、修改數據文件目錄，文件名
SQL> alter database rename file '/u01/app/oracle/tt.dbf' to '/u01/app/oracle/oradata/orcl/tt01.dbf';
Database altered.
6、啟動數據庫到open狀態
SQL> alter database open;
Database altered.
7、再次查看數據文件目錄
SQL> select tablespace_name,file_name from dba_data_files;
TABLESPACE_NAME FILE_NAME
--------------- --------------------------------------------------
PAR /u01/app/oracle/oradata/orcl/par01.dbf
TEST /u01/app/oracle/oradata/orcl/test01.dbf
USERS /u01/app/oracle/oradata/orcl/users01.dbf
UNDOTBS1 /u01/app/oracle/oradata/orcl/undotbs01.dbf
SYSAUX /u01/app/oracle/oradata/orcl/sysaux01.dbf
SYSTEM /u01/app/oracle/oradata/orcl/system01.dbf
TT /u01/app/oracle/oradata/orcl/tt01.dbf
二、在線修改數據文件目錄、文件名
1、創建測試數據文件，測試表
SQL> create table tttt (id int) tablespace tt;
Table created.
SQL> insert into tttt values (1);
1 row created.
SQL> select * from tttt;
ID
----------
1
2、查看當前數據文件目錄、文件名
SQL> select tablespace_name,file_name from dba_data_files;
TABLESPACE_NAME FILE_NAME
--------------- --------------------------------------------------
PAR /u01/app/oracle/oradata/orcl/par01.dbf
TEST /u01/app/oracle/oradata/orcl/test01.dbf
USERS /u01/app/oracle/oradata/orcl/users01.dbf
UNDOTBS1 /u01/app/oracle/oradata/orcl/undotbs01.dbf
SYSAUX /u01/app/oracle/oradata/orcl/sysaux01.dbf
SYSTEM /u01/app/oracle/oradata/orcl/system01.dbf
TT /u01/app/oracle/oradata/orcl/tt01.dbf
3、表空間offline
SQL> alter tablespace tt offline;
Tablespace altered.
4、移動數據文件目錄，修改文件名
SQL> ho mv /u01/app/oracle/oradata/orcl/tt01.dbf /u01/app/oracle/tt.dbf
5、修改數據文件目錄，文件名
SQL> alter database rename file '/u01/app/oracle/oradata/orcl/tt01.dbf' to '/u01/app/oracle/tt.dbf';
Database altered.
6、表空間online
SQL> alter tablespace tttt online;
Tablespace altered.
7、驗證數據
SQL> select * from tttt;
ID
----------
1
8、驗證數據文件目錄，文件名
SQL> select tablespace_name,file_name from dba_data_files;
TABLESPACE_NAME FILE_NAME
--------------- --------------------------------------------------
PAR /u01/app/oracle/oradata/orcl/par01.dbf
TEST /u01/app/oracle/oradata/orcl/test01.dbf
USERS /u01/app/oracle/oradata/orcl/users01.dbf
UNDOTBS1 /u01/app/oracle/oradata/orcl/undotbs01.dbf
SYSAUX /u01/app/oracle/oradata/orcl/sysaux01.dbf
SYSTEM /u01/app/oracle/oradata/orcl/system01.dbf
TT /u01/app/oracle/tt.dbf
7、驗證數據
SQL> select * from tttt;
ID
----------
1
8、驗證數據文件目錄，文件名
SQL> select tablespace_name,file_name from dba_data_files;
TABLESPACE_NAME FILE_NAME
--------------- --------------------------------------------------
PAR /u01/app/oracle/oradata/orcl/par01.dbf
