oracle查看锁表

--查看被锁表
SELECT substr(v$lock.sid,1,4) "SID",
       substr(username,1,12) "UserName",
       substr(object_name,1,25) "ObjectName",

      AND username IS NOT NULL
      AND username NOT IN ('SYS','SYSTEM')
      AND SERIAL# != 1);

--查看表级锁
SELECT /*+ rule*/ 
  a.sid, b.owner, object_name, object_type 
  FROM v$lock a, all_objects b 
  WHERE TYPE = 'TM' 
  and a.id1 = b.object_id;

--查看表级锁的sid 和  serial#
SELECT sid,serial# FROM v$session WHERE sid =518; 

--杀掉锁表进程
alter system kill session '518,64232';
