oracle删除DBF文件 曾经以为把所有的表清空drop掉后其文件已经删除,但实质DBF数据文件依然还存在,在ORADATA文件下。必须要这样删除

 

 

DROP TABLESPACE tablespace_name 
                                  [ including contents [ and datafiles ] [ CASCADE CONSTRAINT ] ]; 
   无选项 -- 当表空间为空才能删除; 
   including contents — 删除表空间及对象; 
   including contents and datafiles — 删除表空间、对象及数据文件; 
   includingcontents CASCADE CONSTRAINT — 删除关联; 
   including contents and datafiles cascade constraint -- 含前两项。 
 
DROP TABLESPACE see including contents and datafiles cascade constraint;
然后在关闭oracle服务,手动删除该DBF文件即可。
