–1、查看被锁的表：
–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
select sess.sid,
sess.serial#,
lo.oracle_username,
lo.os_user_name,
ao.object_name,
lo.locked_mode,
sess.machine,
sess.terminal,
sess.logon_time
from v$locked_object lo,
dba_objects ao,
v$session sess
where ao.object_id = lo.object_id and lo.session_id = sess.sid;
–2、解锁：
alter system kill session ‘2703,15149’;
–sid,serial#是上面查询出来的
–连接操作系统杀掉进行
–查出session的spid
select spid, osuser, s.program
from v$session s, v$process p
where s.paddr = p.addr
and s.sid =149;
–kill -9 上一步查出来的spid
–杀掉线程
