oracle记录被另一个用户锁住怎么办

oracle记录被另一个用户锁住怎么办

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
