oracle 查看锁表及解锁的语句

解锁语句：

alter system kill session \'sid, serial#\'; 
alter system kill session \'23, 1647\';

查询那些对象被锁：

select object_name,machine,s.sid,s.serial# from v$locked_object l,dba_objects o ,v$session s where l.object_id　=　o.object_id and l.session_id=s.sid;

杀死一个进程：

alter system kill session \'24,111\'; -- (其中24,111分别是上面查询出的sid,serial#)
