一般Oracle安装好之后的默认端口为1521，为了安全。如何更改。
1、查看监听端口：
C:\Documents and Settings\mengzhaoliang>lsnrctl status
LSNRCTL for 32-bit Windows: Version 10.2.0.1.0 - Production on 17-12月-2008 18:2

正在连接到 (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=orcl)))
LISTENER 的 STATUS
------------------------

?(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=127.0.0.1)(PORT=1521)))
服务摘要..

命令执行成功
?
2、改变端口号
在D:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\listener.ora文件
LISTENER =
? (DESCRIPTION_LIST =
??? (DESCRIPTION =
????? (ADDRESS = (PROTOCOL = IPC)(KEY = orcl))
????? (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
??? )
? )
改成：
LISTENER =
? (DESCRIPTION_LIST =
??? (DESCRIPTION =
????? (ADDRESS = (PROTOCOL = IPC)(KEY = orcl))
????? (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1568))
??? )
? )
?
3、停止监听命令：
C:\Documents and Settings\mengzhaoliang>lsnrctl stop
LSNRCTL for 32-bit Windows: Version 10.2.0.1.0 - Production on 17-12月-2008 18:30:31
Copyright (c) 1991, 2005, Oracle.? All rights reserved.
正在连接到 (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=orcl)))
命令执行成功
4、重启监听命令：
C:\Documents and Settings\mengzhaoliang>lsnrctl start
LSNRCTL for 32-bit Windows: Version 10.2.0.1.0 - Production on 17-12月-2008 18:30:44
Copyright (c) 1991, 2005, Oracle.? All rights reserved.
启动tnslsnr: 请稍候...
TNSLSNR for 32-bit Windows: Version 10.2.0.1.0 - Production
系统参数文件为D:\oracle\product\10.2.0\db_1\network\admin\listener.ora
写入D:\oracle\product\10.2.0\db_1\network\log\listener.log的日志信息
监听: (DESCRIPTION=(ADDRESS=(PROTOCOL=ipc)(PIPENAME=\\.\pipe\orclipc)))
监听: (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=127.0.0.1)(PORT=1568)))
正在连接到 (DESCRIPTION=(ADDRESS=(PROTOCOL=IPC)(KEY=orcl)))
LISTENER 的 STATUS

服务摘要..
服务 "orcl" 包含 1 个例程。
? 例程 "orcl", 状态 UNKNOWN, 包含此服务的 1 个处理程序...
命令执行成功
这样就可以成功更改监听端口号了
?
5、测试是否成功进入数据库
用超级用户可以连接上数据库SQL>sqlplus "/as sysdba"
但用普通用户不可以，如SQL>sqlplus?test/test@ORCL
用户连接不是数据库：出现：
ERROR:
ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务
?
原来listener.ora内容：
# listener.ora Network Configuration File:? D:\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 = E:\oracle\product\10.2.0\db_1)
????? (PROGRAM = extproc)
??? )
? )
LISTENER =
? (DESCRIPTION_LIST =
??? (DESCRIPTION =
????? (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
????? (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
??? )
? )
改成（红色部分为增加、修改部分）：
# listener.ora Network Configuration File:? D:\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 = D:\oracle\product\10.2.0\db_1)
????? (PROGRAM = extproc)
??? )
??(SID_DESC =
??? (GLOBAL_DBNAME = ORCL)
??? (ORACLE_HOME = D:\oracle\product\10.2.0\db_1)??
??? (SID_NAME = ORCL)
??? )
? )
LISTENER =
? (DESCRIPTION_LIST =
??? (DESCRIPTION =
????? (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
????? (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1568))
??? )
? )
tnsnames.ora的文件内容为：
# tnsnames.ora Network Configuration File: D:\oracle\product\10.2.0\db_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.
ORCL?=
? (DESCRIPTION =
??? (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1568))
??? (CONNECT_DATA =
????? (SERVER = DEDICATED)
????? (SERVICE_NAME = ORCL)
??? )
? )
EXTPROC_CONNECTION_DATA =
? (DESCRIPTION =
??? (ADDRESS_LIST =
????? (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
??? )
??? (CONNECT_DATA =
????? (SID = PLSExtProc)
????? (PRESENTATION = RO)
??? )
? )
?
最后在windows中的“控制面板”——》“管理工具”——》“服务”中把Oracle的listener服务器（OracleOraDb10g_home1TNSListener）重新启动
?
6、再用普通用户登陆可以进入数据库：
SQL>sqlplus?test/test@ORCL
成功进入数据库了
?

附录：
如果在用本地Oracle连接远程的Oracle数据库，在$ORACLE_HOME\NETWORK\ADMIN\tnsnames.ora（如：D:\oracle\product\10.2.0\db_1\NETWORK\ADMIN\tnsnames.ora）增加上远程数据库的信息。这样可以用PLSQL等第三方软件连接。
增加信息：如：
ORCL=
? (DESCRIPTION =
??? (ADDRESS = (PROTOCOL = TCP)(HOST = 10.169.1.118)(PORT = 1568))
??? (CONNECT_DATA =
????? (SID=ORCL)
????? (SERVER = DEDICATED)
??? )
? )
