【强调一点】
动态注册默认只注册到默认的监听器上(名称是LISTENER、端口是1521、协议是TCP)，如果需要向非默认监听注册，则需要配置local_listener参数。
此文不讨论通过设置local_listener参数完成监听的的动态注册。我们将采用“静态注册”的方法来完成监听端口的调整。

【修改步骤】
1.修改listener.ora文件，端口从1521修改成1526；同时将监听改为“静态注册”
listener.ora文件修改前：
ora10g@testdb /home/oracle$ cat $ORACLE_HOME/network/admin/listener.ora
# listener.ora Network Configuration File: /oracle/app/oracle/product/10.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /oracle/app/oracle/product/10.2.0/db_1)
      (PROGRAM = extproc)
    )
)

LISTENER =
(DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 144.194.192.183)(PORT = 1521)(IP = FIRST))
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
)

listener.ora文件修改后：
ora10g@testdb /home/oracle$ cat $ORACLE_HOME/network/admin/listener.ora
# listener.ora Network Configuration File: /oracle/app/oracle/product/10.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = /oracle/app/oracle/product/10.2.0/db_1)
      (PROGRAM = extproc)
    )
    (SID_DESC =   ## 静态注册在这里体现
      (GLOBAL_DBNAME = ora10g)
      (ORACLE_HOME = /oracle/app/oracle/product/10.2.0/db_1)
      (SID_NAME = ora10g)
    )
)

LISTENER =
(DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 144.194.192.183)(PORT = 1526)(IP = FIRST)) ## 端口修改在这里体现
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
)

2.修改tnsnames.ora文件，将其中出现的1521端口号修改为1526
ora10g@testdb /home/oracle$ cat $ORACLE_HOME/network/admin/tnsnames.ora
# tnsnames.ora Network Configuration File: /oracle/app/oracle/product/10.2.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

ORA10G =
(DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 144.194.192.183)(PORT = 1526))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = ora10g)
    )
)

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
    )
    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )
)

3.重新启动LISTENER
LSNRCTL> stop
LSNRCTL> start
Starting /oracle/app/oracle/product/10.2.0/db_1/bin/tnslsnr: please wait...

4.使用“ora10g”进行测试
ora10g@testdb /home/oracle$ sqlplus sec/sec@ora10g

SQL*Plus: Release 10.2.0.1.0 - Production on Tue Jul 21 16:21:32 2009

Copyright (c) 1982, 2005, Oracle. All rights reserved.

Connected to:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production
With the Partitioning, Oracle Label Security, OLAP and Data Mining Scoring Engine options

sec@ora10g>

一切OK，修改成功！

5.小结
使用“静态注册”方法修改监听端口的步骤如下：
1）修改listener.ora文件，端口从1521修改成1526；同时将监听改为“静态注册”；
2）修改tnsnames.ora文件，将其中出现的1521端口号修改为1526；
3）重新启动LISTENER；
4）测试。

Good luck.
