注：需要DBA权限

1、执行以下语句可查询被锁的表

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;

如图

2、执行以下语句可查询被锁的session和serial

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;

如图

3、删除锁住的session和serial

--参照步骤二查询出来的结果 替换掉我的33,35
alter system kill session '33,35';

 

到这里就解锁成功了
