本想在本地上还原错误信息，没还原成功。按照你的配置我在虚拟机和本机之间测试一小下。连接上了。附上官方说明，希望对你有帮助
Check Oracle Net administration in the following ways: -- When using TNSNAMES.ORA or an Oracle Names server, make sure that the client
connection to the Oracle server uses the correct service name or SID. -- Check
LISTENER.ORA on the connection end point's host machine to assure that this
service name or SID refers to the correct server. -- Confirm in TNSNAMES.ORA or
the equivalent service definition that the connect string does not contain
(HS=). -- Set SQLNET.AUTHENTICATION_SERVICES to NONE when using DRCP on
Windows.

你这个ping 能通么？
如果能要开启oracle监听 才能连接，并且要启动数据库
