第一種 

alter tablespace users rename datafile '==' to ‘***';

這種方式需要數據庫處於open狀態，表空間在offline的狀態下才能更改。

 

SQL> alter tablespace users rename datafile '/opt/ora10g/oradata/orcl/user0100.dbf','/opt/ora10g/oradata/orcl/user099.dbf' to '/opt/ora10g/oradata/orcl/userrename1.dbf','/opt/ora10g/oradata/orcl/userrename2.dbf';
alter tablespace users rename datafile '/opt/ora10g/oradata/orcl/user0100.dbf','/opt/ora10g/oradata/orcl/user099.dbf' to '/opt/ora10g/oradata/orcl/userrename1.dbf','/opt/ora10g/oradata/orcl/userrename2.dbf'

ORA-01110: data file 107: '/opt/ora10g/oradata/orcl/user0100.dbf'

SQL> alter tablespace users offline;
Tablespace altered.

SQL> alter tablespace users rename datafile '/opt/ora10g/oradata/orcl/user0100.dbf','/opt/ora10g/oradata/orcl/user099.dbf' to '/opt/ora10g/oradata/orcl/userrename1.dbf','/opt/ora10g/oradata/orcl/userrename2.dbf';
alter tablespace users rename datafile '/opt/ora10g/oradata/orcl/user0100.dbf','/opt/ora10g/oradata/orcl/user099.dbf' to '/opt/ora10g/oradata/orcl/userrename1.dbf','/opt/ora10g/oradata/orcl/userrename2.dbf'

SQL> !

l/userrename2.dbf
[oracle@rac1 ~]$ exit
exit

SQL> alter tablespace users rename datafile '/opt/ora10g/oradata/orcl/user0100.dbf','/opt/ora10g/oradata/orcl/user099.dbf' to '/opt/ora10g/oradata/orcl/userrename1.dbf','/opt/ora10g/oradata/orcl/userrename2.dbf';
Tablespace altered.

SQL> alter tablespace users online;
Tablespace altered.

第二種

alter database rename file ‘==='  to '***';

這種方式需要數據庫處於mount狀態 

SQL> startup mount
ORACLE instance started.

SQL> alter database rename file '/opt/ora10g/oradata/orcl/userrename2.dbf','/opt/ora10g/oradata/orcl/userrename1.dbf' to '/opt/ora10g/oradata/orcl/user099.dbf','/opt/ora10g/oradata/orcl/user0100.dbf';

Database altered.

SQL> alter database open;
alter database open
*
ERROR at line 1:
ORA-01113: file 106 needs media recovery
ORA-01110: data file 106: '/opt/ora10g/oradata/orcl/user099.dbf'
--這里不能open的原因是剛剛關閉數據庫寫了userrename2.dbf和userrename1.dbf這兩個數據文件的scn，而user099.dbf和user0100.dbf的scn還是offline的時候的，這樣控制文件的頭和數據文件頭不一致，所以數據庫打不開。

SQL> alter database rename file '/opt/ora10g/oradata/orcl/user099.dbf','/opt/ora10g/oradata/orcl/user0100.dbf' to '/opt/ora10g/oradata/orcl/userrename2.dbf','/opt/ora10g/oradata/orcl/userrename1.dbf';

Database altered.

SQL> alter database open;

Database altered.

 

另外附上批量修改數據文件名的語句

set pagesize 999
set linesize 999
select 'alter database rename file '||''''||member||''''||' to '||chr(39)||replace(member,'/paic/hq/bk/restore/data/oradata/lass/','/paic/z4ah8020/stg/lass/oradata/hs03lass/')||''';'
from v$logfile
where member like '/paic/hq/bk/restore/data/oradata/lass/%';

select 'alter database rename file '||''''||name||''''||' to '||chr(39)||replace(name,'/paic/hq/bk/restore/data/oradata/lass/','/paic/z4ah8020/stg/lass/oradata/hs03lass/')||''';'
from v$datafile
