(1)锁表查询的代码有以下的形式：
select count(*) from v$locked_object;
select * from v$locked_object;

(2)查看哪个表被锁
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;

(3)查看是哪个session引起的
select a.OS_USER_NAME, c.owner, c.object_name, b.sid, b.serial#, logon_time
  from v$locked_object a, v$session b, dba_objects c
 where a.session_id = b.sid
   and a.object_id = c.object_id
 order by b.logon_time;

(4)杀掉对应进程
执行命令：alter system kill session "1025,41";  需要用户有权限操作
其中1025为sid,41为serial#.
