1、win + r,输入cmd进入界面。
2、输入命令tnsping orcl
3、报错 TNS-03505:无法解析名称
4、查看D:\software\WINDOWS.X64_193000_db_home\network\admin\sqlnet.ora配置信息，修改成如下：
# This file is actually generated by netca. But if customers choose to
# install "Software Only", this file wont exist and without the native
# authentication, they will not be able to connect to the database on NT.
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES,HOSTNAME)
5、查看D:\software\WINDOWS.X64_193000_db_home\network\admin\tnsnames.ora，修改成如下
# tnsnames.ora Network Configuration File: #D:\software\WINDOWS.X64_193000_db_home\NETWORK\ADMIN\tnsnames.ora
# Generated by Oracle configuration tools.

(PRESENTATION = RO)
)
)
ORCL =

(CONNECT_DATA =

6、输入命令tnsping orcl，报错TNS-12541: TNS: 无监听程序
7、开始菜单点击Net Configuration Assistant，添加监听程序，如果报不能创建监听程序，把D:\software\WINDOWS.X64_193000_db_home\NETWORK\ADMIN\listener.ora删掉，再次添加会重新生成这个文件
8、tnsping orcl，ok
----D:\software\WINDOWS.X64_193000_db_home(Oracle_Home目录)
