1.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;

2.杀掉锁表进程SQL语句：
如有记录则表示有lock，记录下SID和serial# ，將记录的ID替換下面的738,1429，即可解除LOCK

 alter system kill session '738,1429';
