oracle查看锁表进程及解锁
查看锁表进程SQL语句1：

select sess.sid,
   sess.serial#,
   lo.oracle_username,
   lo.os_user_name,
   ao.object_name,
   lo.locked_mode
   from v$locked_object lo,
   dba_objects ao,
   v$session sess
where ao.object_id = lo.object_id and lo.session_id = sess.sid;

查看锁表进程SQL语句2：

select * from v$session t1, v$locked_object t2 where t1.sid = t2.SESSION_ID;

杀掉锁表进程：
如有記錄則表示有lock，記錄下SID和serial# ，將記錄的ID替換下面的738,1429，即可解除LOCK

alter system kill session '738,1429';
