oracle中查看表是否被锁
查看表是否被锁
SELECT /*+ rule*/
a.sid, b.owner, object_name, object_type
FROM v$lock a, all_objects b
WHERE TYPE = 'TM'
and a.id1 = b.object_id;

查到的都是被锁的表

这样可以把它杀掉

SELECT sid,serial# FROM v$session WHERE sid = &sid;
alter system kill session ‘sid,serial#’;

要想查到更详细的信息

select a.sid, b.serial#, b.username, b.osuser, b.machine, b.program, c.object_name,d.spid ,
decode(a.type,
