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

db11@oracle  /u01/app/oracle11g/product/11.2.0/dbhome_1/network/admin$ lsnrctl status
