查看被锁的表

select b.owner,b.object_name,a.session_id,a.locked_mode 
from v$locked_object a,dba_objects b where b.object_id = a.object_id;

查看那个用户那个进程照成死锁

select b.username,b.sid,b.serial#,logon_time from 
v$locked_object a,v$session b where a.session_id = b.sid 
order by b.logon_time;

查看连接的进程

SELECT sid, serial#, username, osuser FROM v$session;

根据sid,serial#杀掉进程

alter system kill session'100,223456';
