本文主要是介绍Oracle“记录被另一个用户锁住” 无法更新删除的解决办法,希望对大家解决编程问题提供一定的参考价值,需要的开发者们随着小编来一起学习吧!
1、查看数据库锁,诊断锁的来源及类型:
select object_id,session_id,locked_mode from v$locked_object;
或者用以下命令:
select b.owner,b.object_name,l.session_id,l.locked_mode
from v$locked_object l, dba_objects b
where b.object_id=l.object_id
SELECT lpad(' ',decode(l.xidusn ,0,3,0))||l.Oracle_username User_name,
o.owner,o.object_name,o.object_type,s.sid,s.serial#
FROM v$locked_object l,dba_objects o,v$session s
WHERE l.object_id=o.object_id
AND l.session_id=s.sid
ORDER BY o.object_id,xidusn DESC
2、找出数据库的serial#,以备杀死:
select t2.username,t2.sid,t2.serial#,t2.logon_time
from v$locked_object t1,v$session t2
where t1.session_id=t2.sid order by t2.logon_time;
3、杀死该session
alter system kill session 'sid,serial#'
用步骤2中查出来的记录,对应进该语句删除
自己测试例子:
select b.owner,b.object_name,l.session_id,l.locked_mode
from v$locked_object l, dba_objects b
where b.object_id=l.object_id
select t2.username,t2.sid,t2.serial#,t2.logon_time
from v$locked_object t1,v$session t2
where t1.session_id=t2.sid order by t2.logon_time;
alter system kill session '305,25'
备注:305,25就是代入第二个语句的查询结果
