查询Oracle锁表和清除锁定

查询（用system或sys用户）

SELECT l.session_id 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 sid, s.serial# ;

清除（将上面查询到的内容替换sid和serial#）

ALTER system KILL session 'sid,serial#';
