查看锁表进程SQL语句

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; 

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';
