Oracle 锁表如何解锁

-- 查询被锁对象数目
select count(1) from v$locked_object;
-- 查询被锁对象
select b.owner,b.object_name,a.session_id,a.locked_mode from v$locked_object a,dba_objects b where b.object_id=a.object_id;
-- 查询被锁对象的连接
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;
-- 关闭被锁对象连接
alter system kill session '111,2222';
