步骤大致是：
实验1.配置一个非默认和默认的动态监听同时存在，非默认监听运行在1525端口
实验2：配置一个非默认端口的动态监听--使用local_listener=的值服务器端的tnsnames.ora里的本地名的方法
实验3.配置一个静态监听，运行在1526端口
数据库内一些参数：
SYS@ bys3>show parameter service
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
service_names string bys3
SYS@ bys3>show parameter db_na
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_name string bys3
SYS@ bys3>show parameter db_unique
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_unique_name string bys3
SYS@ bys3>show parameter db_domain
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_domain string
SYS@ bys3>show parameter instance_na
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
instance_name string bys3
关于这几个参数的设置及替换，详见：ORACLE监听之动态监听与静态监听特点
配置默认监听加非默认动态监听示例
1.配置listener.ora，增加非默认动态监听的地址、端口条目
[oracle@bys3 admin]$ more 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 = bys3.bys.com)(PORT = 1525))
(ADDRESS = (PROTOCOL = TCP)(HOST = bys3.bys.com)(PORT = 1521))
)
)
ADR_BASE_LISTENER = /u012.在数据库中配置 local_listener参数,语句如下：--就是把listener.ora中的几行复制过来，注意换行的括号不要少了。
alter system set local_listener='(
DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = bys3.bys.com)(PORT = 1525))
(ADDRESS = (PROTOCOL = TCP)(HOST = bys3.bys.com)(PORT = 1521)))';
SYS@ bys3>alter system register; --手动注册，或者等上一分钟，让PMON自动进行动态监听注册。 因为这里是local_listener的值是两行ADDRESS，要把DESCRIPTION =也加上。如果是一行，不需要加。如：alter system set local_listener='(ADDRESS = (PROTOCOL = TCP)(HOST = bys3.bys.com)(PORT = 1525))';
3.查看监听状态，动态监听已经注册成功：

配置单一一个非默认监听的示例：--参数local_listener值改为tnsnames.ora中的本地名
1.需要把非默认的监听器添加到listener.ora:
[oracle@bys3 admin]$ cat listener.ora
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = bys3.bys.com)(PORT = 1529))
)
)
2.服务器端的tnsnames.ora里添加：
[oracle@bys3 admin]$ cat tnsnames.ora
hello =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = bys3.bys.com)(PORT =1529))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = hello)
)
)
在这个实验中，local_listener='hello';这样配置时，tnsnames.ora中 (SERVICE_NAME = hello)这一行是无效的，也就是不会应用这个服务名。。 sqlplus aa/bb@hello 这样用本地名连接时，当然会用到了。
3.修改local_listener=的值为服务器端的tnsnames.ora里的本地名
SYS@ bys3>alter system set local_listener='hello';
System altered.
SYS@ bys3>show parameter local_l
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string hello
注意注意：如果在配置好之后，tnsnames.ora里内容发生了变化，hello =本地名被删改了总之是找不到这个字段，重启数据库会报错：
ORA-00119: invalid specification for system parameter LOCAL_LISTENER
ORA-00132: syntax error or unresolved network name 'aa'
但是如果数据库未重启，而删除tnsnames.ora或hello =本地名的字段是没影响的，应该是信息已经加载到内存了。
4.重启监听后查看监听状态： --这里的服务名还是来自数据库参数service_names
