2. Server-side Network Configuration
2.1 Create a listener using the default listener name.
2.1.1 The TCP/IP protocol will be used for all connections. Use the machine name(not the IP address) for host.
2.1.2 This listener will listen on the default port.
2.1.3 Databases: PROD and EMREP(created later) will be serviced by this listener.
2.2 Add a second listener , named LSNR2,which will listen on port 1526.Configure this listener to support only automatic instance registrations.
2.2.1 Set up the PROD instance to automatically register with the LSNR2.
2.3 Start both listeners.
参考联机文档：
Net Services Reference ==> 7 Listener Parameters (listener.ora)
Example 7-1 shows a listener.ora file for a listener named LISTENER, which is the default name of the
listener.

2.1 Create a listener using the default listener name. 创建一个监听，使用缺省的监听名字
2.1.1 The TCP/IP protocol will be used for all connections. Use the machine name(not the IP address) for host.
使用TCP/IP协议，使用机器名称，不使用IP地址
2.1.2 This listener will listen on the default port.缺省端口1521
2.1.3 Databases: PROD and EMREP(created later) will be serviced by this listener.
- 修改如下：
- 1.创建一个监听，使用缺省的监听名字LISTENER，使用TCP/IP协议，使用机器名称（不使用IP地址），缺省端口1521.两个数据库PROD和EMREP

2.2 Add a second listener , named LSNR2,which will listen on port 1526.Configure this listener to support only automatic instance registrations.
再配置一个监听，名字叫LSNR2，端口是1526,只支持动态监听。
- 3.追加内容，监听名称为LSNR2，端口为1526，并启动监听LSNR2
这里动态监听即为在listener名称下面没有SID_LIST_LISTENER，注意下面的端口和KEY（与上面的LISTENER的KEY不同）。

2.2.1 Set up the PROD instance to automatically register with the LSNR2.
将PROD实例自动注册到LSNR2。
- 4.将PROD实例动态注册到LSNR2中。
这里即是修改local_listener的参数。

Reference ==> LOCAL_LISTENER参数
LOCAL_LISTENER
| Property | Description |
|---|---|
| Parameter type | String |
| Syntax |
LOCAL_LISTENER = network_name |
| Default value |
(ADDRESS = (PROTOCOL=TCP)(HOST=hostname)(PORT=1521)) where hostname is the network name of the local host. |
| Modifiable |
ALTER SYSTEM |
| Basic | No |
LOCAL_LISTENER specifies a network name that resolves to an address or address list of Oracle Net local listeners (that is, listeners that are running on the same machine as this instance). The address or address list is specified
in the TNSNAMES.ORA file or other address repository as configured for your system.
SQL> alter system set local_listener='(ADDRESS = (PROTOCOL=TCP)(HOST=ocm1.localdomain)(PORT=1526))';
System altered.
