oracle锁表记录查询和解除

oralce中查询锁表记录以及解锁

 

先查询那些表被锁定了

select b.owner,b.object_name,a.session_id,a.locked_mode

from v$locked_object a,dba_objects b

where b.object_id = a.object_id;

查询出被锁定的表的 sid 和serial# 然后kill

select b.username,b.sid,b.serial#,logon_time 

from v$locked_object a,v$session b

where a.session_id = b.sid and sid in(

select a.SESSION_ID

from v$locked_object a,dba_objects b

where b.object_id = a.object_id) order by b.logon_time

解锁

alter system kill session '589,2693' immediate;（589 是sid,2693是serial）

另外作此操作的必须要有数据库管理的权限否则无法解锁。
