查看oracle死锁进程并结束死锁

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';

select 'alter system kill session '''||b.sid||','||b.serial#||''';'
from v$locked_object a,v$session b
where a.session_id = b.sid
order by b.logon_time
