Oracle中的死锁

算是一个工具吧，处理死锁问题

--查询死锁

SELECT /*+ rule */ s.username,
decode(l.type,'TM','TABLE LOCK',
'TX','ROW LOCK',
NULL) LOCK_LEVEL,
o.owner,o.object_name,o.object_type,
s.sid,s.serial#,s.terminal,s.machine,s.program,s.osuser from 
V$lock l,dba_objects o,V$session s
WHERE l.sid = s.sid
AND l.id1 = o.object_id(+)
AND s.username is NOT NULL;

--删除死锁

alter system kill session '152,4574';
alter system kill session 'SID,SERIAL#';
