服务端的监听器有多种配置方法：1、默认的情况下是一个监听器一个端口，这个时候，

不需要在tnsnames.ora文件里解析监听器信息；2、多个监听器多个端口(端口号可以相同)，

这时候，需要在tnsnames.ora文件里解析监听器信息；3、一个监听器多个端口号的监听器，

这时候同样需要在tnsnames.ora文件里解析监听器信息。

以下是测试第3种情况的过程：

----配置多端口号的监听器：

---配置服务端listener.ora文件：

[oracle@enmo admin]$ cat listener.ora

# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora

# Generated by Oracle configuration tools.

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = enmo)(PORT = 1521))

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

)

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = enmo)(PORT = 1526))

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1526))

)

)

---配置服务端tnsnames.ora文件：

[oracle@enmo admin]$ cat tnsnames.ora

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = enmo)(PORT = 1521))

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

)

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = enmo)(PORT = 1526))

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1526))

)

)

[oracle@enmo admin]$

#配置服务端tnsnames.ora文件是为了解析服务端LISTENER 监听器有两个端口号。

---在数据库修改本地的监听器：

sys@PROD>alter system set local_listener='LISTENER';

System altered.

#修改成功。

---启动服务器端的监听器：

LSNRCTL> start
