oracle查看表被锁，以及解锁

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';
