--杀掉锁表进程： 
--如有記錄則表示有lock，記錄下SID, serial# ，將記錄的ID替換下面的1143,24155，即可解除LOCK 
alter system kill session ‘1143,24155‘;

--用这个可以查（可以查看哪台机器哪个用户锁了记录, 其中command是用来杀掉锁住记录的session ）：

-- SELECT-SQL2 功能:检查被加锁的对象以及加锁的会话信息 
-- ALTER-SQL1 功能:杀死会话(SESSION_ID,SERIAL#),可以手工解除锁 
-- 请手工修改SESSION_ID,SERIAL#为相应值 
-- 注意:本功能慎重使用,有一定的破坏性,该SQL可以断开客户机和服务器的连接
