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

?
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！
