查看oracle数据库那些表被锁，用下面SQL
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：
如有记录則表示有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 '245,560';
