本文介绍如何修改Oracle数据库监听端口，并确保实例正确注册。包括修改listener.ora文件、设置LOCAL_LISTENER参数、使用静态监听等多种方法。
我们都知道，Oracle的监听默认端口是1521，但是如果系统上1521已经被占用或业务要求不用默认端口，则需要修改监听的默认端口。
修改监听端口只需要修改配置文件listiner.ora，然后重启监听就行了。但是Oracle实例的PMON进程还是会去找监听1521端口的监听进程去注册，所以同时也需要修改数据库的配置。数据库里只需要在线修改LOCAL_LISTINER即可。
下面以11.2.0.4为例测试修改监听端口：
1、修改监听端口

至此，监听端口已经修改完毕，这时Oracle实例是无法注册到此监听上的。

修改完后，可以看到数据库实例立即注册到监听器上。

修改监听端口完成。
4、把Oracle实例的注册端口改回1521

sys@ORCL>alter system

官方文档中还提供了另一种配置LOCAL_LISTINER的方法：
在tnsnames.ora中添加配置，然后配置LOCAL_LISTINER为tnsnames.ora中的名字即可

另外还可以使用静态监听的方法来修改监听的端口，但是Oracle实例不是“主动”注册到监听器上的。
