windows下如何修改oracle的默认监听端口号port

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
# 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")
    )
   (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。

好了，修改完后，从services.msc里重启oracle监听器即可。
