第一步：打开Oracle Net Manager
进行如下配置：
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
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！
