给锁住的行解锁(oracle)
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
SELECT lpad(‘
‘,decode(l.xidusn ,0,3,0))||l.oracle_username User_name,
o.owner,o.object_name,o.object_type,s.sid,s.serial# FROM v$locked_object
l,dba_objects o,v$session s WHERE l.object_id=o.object_id AND
l.session_id=s.sid ORDER BY o.object_id,xidusn DESC
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#‘
用步骤2中查出来的记录,对应进该语句删除
