第一种
alter tablespace users rename datafile ‘==‘ to ‘***‘;
这种方式需要数据库处于open状态，表空间在offline的状态下才能更改。
- 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‘;

第二种
alter database rename file ‘===‘ to ‘***‘;
这种方式需要数据库处于mount状态
- SQL> startup mount

-
- Database altered.
-
- SQL> alter database open;
-
- Database altered.
另外附上批量修改数据文件名的语句
- 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
- where name 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$tempfile
