oracle中死锁的处理

1、临时表

WITH TMPTABLE AS (select * from dual)

select * from tmptable

2、死锁查询：

SELECT /*+ rule */ s.username,decode(l.type, 'TM', 'TABLE LOCK', 'TX', 'ROW LOCK', l.type) LOCK_LEVEL,

o.owner,o.object_name,o.object_type,s.sid,s.serial#,s.terminal,s.machine,s.program,s.osuser

FROM v$session s, v$lock l, dba_objects o

WHERE l.sid = s.sid

AND l.id1 = o.object_id(+)

AND s.username is NOT NULL

解锁：

    杀死该session： alter system kill session 'sid,serial#'
