oracle数据库解锁

oracle数据库表锁住

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

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#'
