oracle_解锁表

--以下几个为相关
SELECT * FROM v$lock;
SELECT * FROM v$sqlarea;
SELECT * FROM v$session;
SELECT * FROM v$process ;
SELECT * FROM v$locked_object;--object_id是对象的ID,session_id是被锁定对象有session ID;
SELECT * FROM all_objects;
SELECT * FROM v$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;

--查出锁定的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;


 

 

这个语句将查找到数据库中所有的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,一个是锁,一个是行锁。

 

--杀掉进程 sid,serial#
alter system kill session‘210,11562‘;
