Oracle查询被锁的表及进程的方法

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';
