首先我们要知道，在oracle中，什么文件里面有关于端口号的信息，路径如下：
X:\oracle_home\product\11.2.0\dbhome_2\NETWORK\ADMIN
到这个路径下我们可以发现有*.ora文件，那么其中listener.ora和tnsnames.ora这两个文件，就是我们这次需要改动的文件
先来看listener.ora
原内容
listener.ora Network Configuration File: D:\oracle11g\product\11.2.0\dbhome_2\network\admin\listener.ora
Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = D:\oracle11g\product\11.2.0\dbhome_2)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:D:\oracle11g\product\11.2.0\dbhome_2\bin\oraclr11.dll")
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
)
ADR_BASE_LISTENER = D:\oracle11g
以上是原文内容，我们的修改如下，红色加粗为修改部分
listener.ora Network Configuration File: D:\oracle11g\product\11.2.0\dbhome_2\network\admin\listener.ora

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = D:\oracle11g\product\11.2.0\dbhome_2)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:D:\oracle11g\product\11.2.0\dbhome_2\bin\oraclr11.dll")
)
(SID_DESC =
(GLOBAL_DBNAME = cisco)
(ORACLE_HOME = D:\oracle11g\product\11.2.0\dbhome_2)
(SID_NAME = cisco)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1522))
)
)
ADR_BASE_LISTENER = D:\oracle11g
我们添加了一个SID_DESC，注意里面的GLOBAL_DBNAME和SID_NAME仍然是你安装oracle时的SID
下面就是在LISTENR里面修改你想要的端口号PORT=xxx
下面再看tnsnames.ora
原文内容
tnsnames.ora Network Configuration File: D:\oracle11g\product\11.2.0\dbhome_2\network\admin\tnsnames.ora
Generated by Oracle configuration tools.
CISCO =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = cisco)
)
)
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)
LISTENER_CISCO =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

修改后的
tnsnames.ora Network Configuration File: D:\oracle11g\product\11.2.0\dbhome_2\network\admin\tnsnames.ora
Generated by Oracle configuration tools.
CISCO =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1522))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = cisco)
)
)
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)
LISTENER_CISCO =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

可以发现基本没什么变化，只是在CISCO里面的端口号发生了变化，PORT改成与listener.ora文件里面端口号相对应的即可。
