oracle11局域网访问 连接失败

访问局域网Oracle 数据库 解决在不能上网的情况下面局域网内无法访问oracle数据库

记住设置完之后要重启电脑，而且设置完之后，如果在没有因特网的情况下面数据库访问很慢

因为oracle服务端访问配置是需要配置访问地址监听的,具体见Oracle安装路径:

% product\11.2.0\dbhome_1\NETWORK\ADMIN\listener.ora

 

这个是我的oracle监听服务的配置文件,内容为

# listener.ora Network Configuration File: E:\app\rcfeng\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 = E:\app\rcfeng\product\11.2.0\dbhome_1)

      (PROGRAM = extproc)

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

    )

  )

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

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

      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

    )

  )

ADR_BASE_LISTENER = E:\app\rcfeng

 

其中

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

(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

是指监听的地址;

由于本机的服务端一般都是自己做测试的时候访问 ;

而为什么我们写localhost:1521 的时候可以访问到,就是因为

(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

这一句,我们监听了localhost,所以可以访问到..

 

如果需要被局域网访问的话,我们只需要加入监听访问地址就可以了,如:

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.120)(PORT = 1521))

 

这样局域网的机子就可以访问我们的oracle服务了..完整内容为:

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

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

      (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.120)(PORT = 1521))

    )
