第一步：打开Oracle Net Manager

进行如下配置：

![20171031113851687][]

![20171031113943303][]

![20171031113954574][]

第二步:找到查看listener.ora文件：位于oracle 安装目录的app文件夹目录下面

我的位置是：G:\\app\\admin\\product\\12.1.0\\dbhome\_1\\NETWORK\\ADMIN\\listener.ora,打开大致如下

# listener.ora Network Configuration File: G:\app\admin\product\12.1.0\dbhome_1\NETWORK\ADMIN\listener.ora
    # Generated by Oracle configuration tools.
    
    SID_LIST_LISTENER =
      (SID_LIST =
        (SID_DESC =
          (SID_NAME = CLRExtProc)
          (ORACLE_HOME = G:\app\admin\product\12.1.0\dbhome_1)
          (PROGRAM = extproc)
        )
      )
    
    LISTENER =
      (DESCRIPTION_LIST =
        (DESCRIPTION =
          (ADDRESS = (PROTOCOL = TCP)(HOST = 10.0.0.217)(PORT = 1521))
        )
        (DESCRIPTION =
          (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
        )
      )
    
    ADR_BASE_LISTENER = G:\app\admin\product\12.1.0\dbhome_1\log

第三步：添加一段配置：

在：

(SID_DESC =
          (SID_NAME = CLRExtProc)
          (ORACLE_HOME = G:\app\admin\product\12.1.0\dbhome_1)
          (PROGRAM = extproc)
        )

后面添加：

(SID_DESC =
          (GLOBAL_DBNAME = ORCL)
          (ORACLE_HOME = G:\app\admin\product\12.1.0\dbhome_1)  
          (SID_NAME = ORCL)
        )

添加完成的文件内容为：

# listener.ora Network Configuration File: G:\app\admin\product\12.1.0\dbhome_1\NETWORK\ADMIN\listener.ora
    # Generated by Oracle configuration tools.
    
    SID_LIST_LISTENER =
      (SID_LIST =
        (SID_DESC =
          (SID_NAME = CLRExtProc)
          (ORACLE_HOME = G:\app\admin\product\12.1.0\dbhome_1)
          (PROGRAM = extproc)
        )
       (SID_DESC =
          (GLOBAL_DBNAME = ORCL)
          (ORACLE_HOME = G:\app\admin\product\12.1.0\dbhome_1)  
          (SID_NAME = ORCL)
        )
      )
    
    LISTENER =
      (DESCRIPTION_LIST =
        (DESCRIPTION =
          (ADDRESS = (PROTOCOL = TCP)(HOST = 10.0.0.217)(PORT = 1521))
        )
        (DESCRIPTION =
          (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
        )
      )
    
    ADR_BASE_LISTENER = G:\app\admin\product\12.1.0\dbhome_1\log

SID\_NAME 对应网络服务命名；GLOBAL\_DBNAME 对应服务名，修改完成后重启服务就好了！
