oracle查看被锁的表和解锁的方法

–以下几个为相关表

select * from v$lock;

select * from v$sqlarea;

select * from v$session;

select * from v$process ;

select * from v$locked_object;

select * from all_objects;

select * from v$session_wait;

–查看被锁的表

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;

–查看那个用户那个进程照成死锁

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;

–查看连接的进程

select sid, serial#, username, osuser from v$session;

–3.查出锁定表的sid, serial#,os_user_name, machine_name, terminal，锁的type,mode

select s.sid, s.serial#, s.username, s.schemaname, s.osuser, s.process, s.machine,

s.terminal, s.logon_time, l.type

from v$session s, v$lock l

where s.sid = l.sid

and s.username is not null

order by sid;

这个语句将查找到中所有的dml语句产生的锁，还可以发现，

任何dml语句其实产生了两个锁，一个是表锁，一个是行锁。

–杀掉进程 sid,serial#

alter system kill session’210,11562′;
