oracle 如何解锁表

--查询被锁的表

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;

--查看是哪个session引起的

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;

--杀掉对应进程即解锁

alter system kill session '432,7303' --其中866是sid 20840是serial#
