[oralce拾遗]oracle修改监听IP地址

来源: 作者: 时间:2016-01-13 16:39 【

在局域网中远程连接oracle时,一直提示拒绝连接,在确定防火墙关闭,oracle服务器监听端口开启的情况下,可能的错误就是oracle的监听IP地址不是预设的那样,而是本地的127 0 0 1。排错

在局域网中远程连接oracle时,一直提示拒绝连接,在确定防火墙关闭,oracle服务器监听端口开启的情况下,可能的错误就是oracle的监听IP地址不是预设的那样,而是本地的127.0.0.1。

排错过程不再细说,这里只分享由于主机名不正确而导致oracle拒绝连接的解决办法。

===============================

修改hosts文件

打开cmd,输入hostname,记下主机名 用记事本打开c:\windows\system32\drivers\etc\hosts 文件,添加主机名
# 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
    [主机IP]          [主机名]

==========================

修改oracle监听文件

1、打开listener.ora,文件在F:\app\young\product\11.2.0\dbhome_1\NETWORK\ADMIN 目录下,将里面的localhost换为自己的主机名。

# listener.ora Network Configuration File: F:\app\young\product\11.2.0\dbhome_1\network\admin\listener.ora
# Generated by  configuration tools.

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = CLRExtProc)
      (ORACLE_HOME = F:\app\young\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:F:\app\young\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
  )

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = Young-PC)(PORT = 1521))//Young-PC原为localhost
) ) ADR_BASE_LISTENER = F:\app\young

2、修改tnsnames.ora,目录同上,也将localhost更改为主机名。

# tnsnames.ora Network Configuration File: F:\app\young\product\11.2.0\dbhome_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

LISTENER_ORCL =
  (ADDRESS = (PROTOCOL = TCP)(HOST = Young-PC)(PORT = 1521))//Young-PC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 = Young-PC)(PORT = 1521))//Young-PC原为localhost
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = orcl)
    )
  )

3、重启tnslsnr。

打开cmd,输入以下命令。

lsnrctl stop
lsnrctl start
lsnrctl stat

这里写图片描述

=============================

再次远程连接,已经可以连上了,成功。
