Oracle数据库锁表的解锁方法

1、下面的语句用来查询哪些对象被锁：
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;

 

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;

 

2、下面的语句用来杀死一个进程：

alter system kill session '198,2979';
