How to connect the client to the Oracle server without installing the oracle database

The premise is that the firewall on the server has been disabled or port 1521 has been replaced.
To connect to the oracle server on a machine without an oracle Server, first install the oracle client.
I am now installing an oracle lite client. After installation, open PLSQL Developer. You will be prompted to enter the user name and password:

Click "cancel". On the displayed page, click "Tools"> "Preferences"

The preceding figure shows how PLSQL Developer connects to the database without installing the oracle server. Next I will explain how Navicat. for. Oracle connects to the database.
Because there are a lot of Navicat. for. Oracle green version downloads on the Internet, but after you download it, you will find that it is not a green version at all. My version is really green and free, and there is a registration machine in it, you can choose according to the actual situation.
After installing the oracle client and Navicat. for. Oracle, open Navicat: Select "Tools"> "options"

PS: Since I have just learned some oracle and I am not very familiar with these things, I can only post it easily. Hope you guys don't laugh ......
