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#'
记得以上是用SYS或者SYSTEM账户进入,要不没权限。
select object_id,session_id,locked_mode from v$locked_object;
