1、查看数据库锁,诊断锁的来源及类型：
　　select object_id,session_id,locked_mode from v$locked_object;
或者用以下命令：
select b.owner,b.object_name,l.session_id,l.locked_mode
from v$locked_object l, dba_objects b
where b.object_id=l.object_id

集群环境可能使用gv视图才能查出

SELECT object_name, machine, s.sid, s.serial# FROM gv$locked_object l, dba_objects o, gv$session s
WHERE l.object_id = o.object_id AND l.session_id = s.sid;

SELECT object_name, machine, s.sid, s.serial# FROM gv$locked_object l, dba_objects o, gv$session s WHERE l.object_id = o.object_id AND l.session_id = s.sid;

2、找出数据库的serial#,以备杀死：
　　 select t2.username,t2.sid,t2.serial#,t2.logon_time
from v$locked_object t1,v$session t2
where t1.session_id=t2.sid order by t2.logon_time;

3、杀死该session
　　alter system kill session 'sid,serial#'

4、查询更详细的锁表信息
