[20160418]修改oracle监听端口.txt
--上午开发提出要修改oracle的监听端口,我以前测试遇到过一些问题:
--链接: http://blog.itpub.net/267265/viewspace-758983/
-- 但是在11.2.0.4下遇到以前不一样的情况,时间太久了,测试在2013年做的,也许现在存在一些变化.
1.无静态注册监听:

--这个时候可以动态注册.执行如下可以登录,看来以前11.2.0.3测试存在的问题实际上是一个bug.

2.再看看看存在静态监听注册的情况:

# (ADDRESS = (PROTOCOL = TCP)(HOST = gxqyydg4)(PORT = 1529))

)

3.总结：
1.看来以前在11.2.0.3遇到的问题,应该是bug.
2.要使用非标准端口，可以使用静态注册。这样可以不要修改参数local_listener.但是动态注册1521端口无效，也就是无法再通过1521
端口连接数据库。
3.使用非标准端口,如果使用非静态注册,必须修改local_listener参数，让动态注册使用非标准的端口来实现,这样就无法使用1521端口。
4.总之,修改监听的缺省端口,无法再使用1521端口连接数据库.
5.看来以前遇到的是bug.要以动态的态度看待oracle,不能报老经验,一句话最好的方法就是测试.
--另外我还发现一些问题,如果配置静态监听并且使用1521端口:
