oracle 記錄被另一個用戶鎖住

oracle 記錄被另一個用戶鎖住

1、查看數據庫鎖,診斷鎖的來源及類型：
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、找出數據庫的serial#,以備殺死：
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、殺死該session
alter system kill session ‘sid,serial#’
用步驟2中查出來的記錄，對應進該語句刪除
