oracle锁表进程查看并强制关闭

查看锁表进程SQL语句1： 
select sess.sid, 
   sess.serial#, 
   lo.oracle_username, 
   lo.os_user_name, 
   ao.object_name, 
   lo.locked_mode 
   from v$locked_object lo, 
   dba_objects ao, 
   v$session sess 
where ao.object_id = lo.object_id and lo.session_id = sess.sid; 


查看锁表进程SQL语句2： 
select * from v$session t1, v$locked_object t2 where t1.sid = t2.SESSION_ID; 

杀掉锁表进程： 
如有記錄則表示有lock，記錄下SID和serial# ，將記錄的ID替換下面的738,1429，即可解除LOCK 
alter system kill session '738,1429'; 




用这个可以查：  select s.sid,s.machine,o.object_name,l.oracle_username,l.locked_mode, 'ALTER  SYSTEM  KILL  SESSION  '''||s.sid||',  '||s.serial#||''';'   Command  from  v$locked_object  l,v$session  s,all_objects  o  where  l.session_id=s.sid  and  l.object_id=o.object_id  
可以查看哪台机器哪个用户锁了记录, 其中command是用来杀掉锁住记录的session
