一、修改默认SCAN listener port

1.1.查看当前SCAN监听器配置

SCAN监听器是一个全局的、集群层面的资源 ，而不是某个节点私有 的。它的配置信息存储在OCR**（Oracle Cluster Registry，Oracle集群注册表）中，这个注册表由整个集群共享。**

所以无论你在节点1还是节点2上执行：srvctl config scan_listener，命令都会去访问同一个共享的OCR，所以执行查询的结果将会完全一致。

1.2.修改SCAN listener port

基于上边的认识，我们在修改SCAN监听器端口时，只需要在一个节点上执行，修改会自动同步到整个集群。

在任意节点（比如 p19c01）的grid用户下执行即可

srvctl stop scan_listener

srvctl modify scan_listener -p 11521

示例：

bash 复制代码 
[root@p19c01 ~]# su - grid

[grid@p19c01 ~]$ srvctl modify scan_listener -p 15212

The command completed successfully

结论：The listener supports no services

**这是因为我们知识修改了 SCAN 监听器的端口，而数据库实例无法向新的 SCAN 端口注册服务。**还需执行以下两步操作，表示让数据库中的服务重新注册到新的端口中

ALTER SYSTEM SET REMOTE_LISTENER='p19c-scan:11512' SCOPE=BOTH;

ALTER SYSTEM REGISTER;

结果：从上边就可以看到当执行完上边两部操作之后，就有服务注册进去了。

二、修改默认Listener Ports

2.1.获取当前监听程序的配置信息.

To get the current settings of your listener on RAC issue the following command: srvctl config listener

The output should be similar to the following Name: LISTENER Network: 1, Owner: oracle Home: End points: TCP:1521

示例：

bash 复制代码 
[grid@p19c01 ~]$ srvctl status listener
监听程序 LISTENER 已启用
监听程序 LISTENER 正在节点上运行: p19c01,p19c02
[grid@p19c01 ~]$
[grid@p19c01 ~]$ srvctl config listener
名称: LISTENER
类型: Database Listener
网络: 1, 所有者: grid
主目录: <CRS home>
端点: TCP:1521
监听程序已启用。

2.2.修改端口

使用类似于修改SCAN listener port的命令的指令来修改所使用的端口：srvctl modify listener -l LISTENER -p "TCP:"。这将更改OCR中的条目，以便侦听器重新启动时能够获取新值。现有连接将保持连接状态。

eg：srvctl modify listener -l LISTENER -p "TCP:1522";

示例：

2.3.手工修改LOCAL_LISTENER

修改了节点监听器的端口，必须告诉数据库实例新的端口号，否则PMON进程找不到监听器，服务就无法注册，客户端也就无法连接。

应手动更改 LOCAL_LISTENER。以下是一个示例：

SQL> alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=)(PORT=))))' scope=both sid='\<您选择的实例\| \* '

示例：

alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.75.111)(PORT=1522))))' scope=both sid='p19c01';

alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.75.112)(PORT=1522))))' scope=both sid='p19c02';

#注：节点2的local_listener输出也就是host不同。

2.4.重新启动监听程序

监听重新启动后，对应配置文件才会更改。

只有在停止并重新启动监听器后，才会更改每个SID的endpoints_listener.ora和local_listener.ora文件。

srvctl stop listener

srvctl start listener

示例：

bash 复制代码 
[grid@p19c01 admin]$ srvctl stop listener
[grid@p19c01 admin]$
[grid@p19c01 admin]$ srvctl start listener
[grid@p19c01 admin]$

2.5.检查监听配置

使用"srvctl config Listener"检查配置。

示例：

bash 复制代码 
[grid@p19c01 admin]$ srvctl config listener
名称: LISTENER
类型: Database Listener
网络: 1, 所有者: grid
主目录: <CRS home>
端点: TCP:1522
监听程序已启用。
监听程序已在以下节点上分别启用:
监听程序已在以下节点上分别禁用:
