Oracle修改监听IP地址

oracle 11g断网安装时，没有检测net的功能，所以安装完后，netstat -an 发现自动监听的是127.0.0.1:1521，这样安装完成后，其他的主机根本无法连接，是什么原因呢？

 

排错后发现，是主机名的问题：

1 在cmd中，输入hostname 发现主机名

2 在文件夹：c:\windows\system32\drivers\etc  修改hosts文件：

源文件为：

 

# Copyright (c) 1993-2009 Microsoft Corp.

#

# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.

#

# This file contains the mappings of IP addresses to host names. Each

# entry should be kept on an individual line. The IP address should

# be placed in the first column followed by the corresponding host name.

# The IP address and the host name should be separated by at least one

# space.

#

# Additionally, comments (such as these) may be inserted on individual

# lines or following the machine name denoted by a '#' symbol.

#

# For example:

#

#      102.54.94.97     rhino.acme.com          # source server

#       38.25.63.10     x.acme.com              # x client host



# localhost name resolution is handled within DNS itself.

#    127.0.0.1       localhost

#    ::1             localhost

....此处添加 主机IP       主机名

 

 

 

在最后一行加入

 本机IP    主机名

保存即可

使用lsnrctl stat查看监听状态

此时监听的还是 127.0.0.1:1521这个IP

 

 

修改监听文件 listener.ora 文件在 D:\app\Administrator\product\11.2.0\dbhome_1\network\admin 目录下，注释部分的主机名原为Localhost

# listener.ora Network Configuration File: D:\app\Administrator\product\11.2.0\dbhome_1\network\admin\listener.ora

# Generated by Oracle configuration tools.

 

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (SID_NAME = CLRExtProc)

      (ORACLE_HOME = D:\app\Administrator\product\11.2.0\dbhome_1)

      (PROGRAM = extproc)

      (ENVS = "EXTPROC_DLLS=ONLY:D:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")

    )

  )

 

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

      (ADDRESS = (PROTOCOL = TCP)(HOST = WIN-ASA0GB1AV61)(PORT = 1521))//WIN-ASA0GB1AV61原为localhost

) ) ADR_BASE_LISTENER = D:\app\Administrator

　

把其中的localhost换成自己的主机名

 

再修改主机名文件 tnsnames.ora

 

# tnsnames.ora Network Configuration File: D:\app\Administrator\product\11.2.0\dbhome_1\network\admin\tnsnames.ora

# Generated by Oracle configuration tools.

 

LISTENER_ORCL =

  (ADDRESS = (PROTOCOL = TCP)(HOST = WIN-ASA0GB1AV61)(PORT = 1521))//WIN..原为localhost

 

 

ORACLR_CONNECTION_DATA =

  (DESCRIPTION =

    (ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))

    )

    (CONNECT_DATA =

      (SID = CLRExtProc)

      (PRESENTATION = RO)

    )

  )

 

ORCL =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = WIN-ASA0GB1AV61)(PORT = 1521))//WIN..原为localhost

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = orcl)

    )

  )

 

同样把localhost换成自己的主机名

再用lsnrctl.ora检测，发现监听IP地址变为：192.168.1.251:1521 0.0.0.0 (192.168.1.251为本主机IP)

 

成功！
