1、查看锁表的信息Oracle数据库中查看锁表信息及解锁

select 
 a.object_name
 ,b.session_id
 ,c.serial#
 ,c.program
 ,c.username
 ,c.command
 ,c.machine
 ,c.lockwait  
 from all_objects a,v$locked_object b,v$session c 
 where a.object_id=b.object_id and c.sid=b.session_id;

2、对表进行解锁

 alter system kill session '$session_id,$serial#'; --$分别为会话id和进程号
