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';
