How to solve Oracle Installation Error With NoMachine

First, I cannot directly log on to linux using oracle on nomachine, so I created a simple user zc. This may also be the root cause of the following errors.

Cat. bash_profile content:

Log on to the remote machine using zc and su to the oracle user. An error occurred while executing runinstaller.

Now I am struggling with the DISPLAY settings!

Run xdpyinfo | grep display as an oracle user to obtain DISPALY information. The result is:

Xdpyinfo: unable to open display "localhost: 0.0 ".

Run xdpyinfo | grep display with the root user. The result is as follows:

Xdpyinfo: unable to open display "localhost: 0.0 ".

So I went back and forth for half a day. Still unsolved

As mentioned at the beginning of the article, I always get the above prompt because I first log on to the zc user and then su to the oracle and root users. I don't know why.

So execute xdpyinfo | grep display under the zc user.

Name of display: 1002.0

Then, su-oracle.

In oracle users, export DISPLAY = locakhost: 1002.0

Run:./runInstaller

Done! Oracle is successfully installed.
