表被锁的解决办法

用下面语句查询那些表被锁。

 

SELECT /*+ rule*/ 
a.sid, b.owner, object_name, object_type 
FROM v$lock a, all_objects b 
WHERE TYPE = 'TM' 
and a.id1 = b.object_id; 

 

 

===============================

 

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';
