oracle查询锁表解锁语句

转自：http://blog.youkuaiyun.com/zhldt2008/article/details/7953932

1. 如下语句 查询锁定的表:

  SELECT l.session_id sid, s.serial#, l.locked_mode,l.oracle_username,

　　l.os_user_name,s.machine, s.terminal, o.object_name, s.logon_time

　　FROM v$locked_object l, all_objects o, v$session s

　　WHERE l.object_id = o.object_id

　　AND l.session_id = s.sid

　　ORDER BY sid, s.serial# ;

 

2.然后删除掉系统锁定的此记录

ALTER system KILL session 'SID,serial#'; 

如果有多个sid 和serial# 重复删除每条记录

3.循环释放锁表资源

DECLare str VARCHAR2(1000);
 BEGIN
   FOR c1 in (  
     SELECT l.session_id sid, s.serial#, l.locked_mode,l.oracle_username,

　　l.os_user_name,s.machine, s.terminal, o.object_name, s.logon_time

　　FROM v$locked_object l, all_objects o, v$session s

　　WHERE l.object_id = o.object_id

　　AND l.session_id = s.sid

 ) LOOP
     str:='ALTER system KILL session '''||c1.sid||','||c1.serial#||'''';
     EXECUTE IMMEDIATE str;
     commit;
   END LOOP;
 END;
