首先执行下面一段代码，得到锁定的进程：
select
t1.sid, t1.serial#, t1.username, t1.logon_time
from v$session t1 , v$locked_object t2
where t1.sid = t2.session_id
order by t1.logon_time;
t1.sid, t1.serial#, t1.username, t1.logon_time
from v$session t1 , v$locked_object t2
where t1.sid = t2.session_id
order by t1.logon_time;
可以得到进程的SID和SERIAL#序号，然后按照下列语句解锁：
alter system kill session 'sid,serial#';
即可，这里我们输入：
alter system kill session '3332,41117#';
