select object_name as 對象名稱,s.sid,s.serial#,p.spid as 系統進程號
 from v$locked_object l , dba_objects o , v$session s , v$process p
 where l.object_id=o.object_id and l.session_id=s.sid and s.paddr=p.addr;
 

--殺死死鎖的進程序
 alter system kill session '89,60085';（89,60085分別是‘sid,s.serial#,’）
 

--找出引起死鎖的話句
 select t2.username,t2.sid,t2.serial#,t2.logon_time,t3.sql_text
      from v$locked_object t1,v$session t2,v$sqltext t3
      where t1.session_id=t2.sid
      and t2.sql_address=t3.address
      order by t2.logon_time;
