修改默认端口号

oracle 监听器如果使用动态注册的话，默认只能动态注册1521端口

如果要修改端口号：必须修改数据库中的参数

local_listener

如下：

1. 监听文件

   db11@oracle  /u01/app/oracle11g/product/11.2.0/dbhome_1/network/admin$ vi listener.ora 
   LISTENER =
   (ADDRESS_LIST=
          (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.2.100)(PORT=1526))
          (ADDRESS=(PROTOCOL=ipc)(KEY=PNPKEY)))

2. 修改参数
   ```
   SQL> show parameter listener

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
listener_networks string
local_listener string
remote_listener string

SQL> alter system set local_listener='(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.2.100)(PORT=1526))';

System altered.

SQL> show parameter listener

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
listener_networks string
local_listener string (ADDRESS=(PROTOCOL=tcp)(HOST=1
92.168.2.100)(PORT=1526))
remote_listener string

3. 查看状态
