数据库锁住

1、查看数据库锁,诊断锁的来源及类型:

select object_id,session_id,locked_mode fromv$locked_object;

或者用以下命令: 

select b.owner,b.object_name,l.session_id,l.locked_modefrom 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 fromv$locked_object t1,v$session t2 where t1.session_id=t2.sid order byt2.logon_time; 

3、杀死该session:   

alter system kill session 'sid,serial#'
