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

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#'
