oracle rac监听和oracle单节点监听不同，rac监听分为远程监听和本地监听：

远程监听即remote_listener也是scan_listener
本地监听即local_listener也是listener

local_listener 默认不需要配置，默认配置指向1521端口，对于需要单实例连接rac数据库实例且对端口有要求的情况，需要改变本地监听端口指向tns里的连接字符串，而在rac配置中默认指向本节点的vip。

remote_listener指向的是scan监听名，需要远程监听配置

1、修改远程监听端口

单节点执行

1.1 查看远程监听状态

切换至grid账号下

[grid@db1 ~]$ srvctl config scan_listener

SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521 #远程监听端口为1521

[grid@db1 ~]$ lsnrctl status LISTENER_SCAN1

scan_listener如果不在节点1，则在另外一个节点查看

1.2 修改SCAN listener端口

在grid用户下进行，命令格式如下

Modify SCAN listener port:

$GRID_HOME/bin/srvctl modify scan_listener -p

Update 11gR2 database init.ora parameter: alter system set remote_listener=':' scope=both;

示例：

[grid@db1 ~] GRID_HOME/bin/srvctl modify scan_listener -p 1525

1.3 为监听注册实例

切换到oracle节点执行

[root@db1 ~]# su - oracle

1.4 重启远端监听scan listener生效新端口

切换至grid

[grid@db1 ~]# srvctl stop scan_listener

[grid@db1 ~]# srvctl start scan_listener

1.5 确认远端监听状态

发现rac集群远端监听端口已经修改完毕
使用sqlplus连接正常

2、修改本地监听端口

双节点都要执行

2.1 获取本地监听程序配置信息

切换到grid执行

[grid@db1 ~]$ srvctl config listener

Name: LISTENER

Network: 1, Owner: grid

Home: <CRS home>

End points: TCP:1521 #本地监听端口为1521

[grid@db1 ~]$ lsnrctl status #查看监听状态
