Oracle记录被另一个用户锁住

1、查看哪个表被锁

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

2、查看引起表锁住的Session

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

3、清除锁住表的Session

alter system kill session 'sid,serial#';
