配置toad远程连接oracle

在oracle服务器上：

C:\app\Administrator\product\11.2.0\dbhome_1\NETWORK\ADMIN目录

文件：listener.ora（10.144.118.12是oracle服务器地址）

# 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 =
    (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")

      (ORACLE_HOME =  C:\app\Administrator\product\11.2.0\dbhome_1) 
      (SID_NAME = ORCL) 
   ) 
  )

    )
  )

    )
    (CONNECT_DATA =

      (PRESENTATION = RO)
    )
  )

ORCL =
  (DESCRIPTION =

配好后重启服务：

客户端需要安装oracle client 和 toad软件，登录界面
