数据库表被锁如何解锁

1.查看被锁的表

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;

2.查看那个用户那个进程照成死锁

Select

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

From v$locke{d}_{o}bjecta,v$session b

Where a.session_id = b.sid order by b.logon_time;

3.杀掉进程

Alter system kill session’210,11562’; //参数为sid,serial#

简单实用
