解决Oracle数据库表被锁死情况下的两个技巧

第一种方法：用系统账户如sys as SYSDBA 登录进去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#' 第二种方法：慢慢等待，据说oracle也会把该进程杀死
