oracle锁表查询操作详解，oracle锁表详解

--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
