1. 查询那些被锁了
SELECT
s.SID,
s.serial#,
l.locked_mode,
l.oracle_username,
l.os_user_name,
s.machine,
s.terminal,
o.object_name,
s.logon_time
FROM v$locked_object l, all_objects o, v$session s
WHERE l.object_id = o.object_id
AND l.session_id = s.sid
ORDER BY logon_time desc, s.serial#;
2. 杀掉
alter system kill session 'sid,serial';
