Oracle 11g 数据库远程访问配置

   

    Oracle  11g 安装完成后，只能在本机访问，希望其远程计算机也能访问，刚开始直接修改listener.ora文件

    # listener.ora Network Configuration File: C:\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 = C:\app\Administrator\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\app\Administrator\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 = C:\app\Administrator

  将localhost直接改为本机Ip地址，重启监听服务

    停止监听：lsnrctl stop 

    启动监听：lsnrctl start 

    查看监听：lsnrctl status 

结果失败。

正确的方式，运行Net Configuration Assistant，修改监听配置，一步一步即可，无需修改任何数据

   

结果listener.ora文件变为：

# listener.ora Network Configuration File: C:\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 = C:\app\Administrator\product\11.2.0\dbhome_1)
      (PROGRAM = extproc)
      (ENVS = "EXTPROC_DLLS=ONLY:C:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
    )
  )


LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = WIN-VI5UF46V3UG)(PORT = 1521))
    )
  )


ADR_BASE_LISTENER = C:\app\Administrator

Host处变为主机名，这样远程计算机就可以访问服务器了。

无需修改服务方式为共享还是专用，无需修改IP地址，可能该向导在后面自动做了很多工作
