(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#.
