how can i set oracle user with X11 environment... trying to solve this problem since 3 days....

First, have you contacted Oracle, since you're paying for support??? If you've been working on this for 3 days, that would've gotten you going 2 1/2 days ago.....

Also, I don't believe that CentOS is an 'oracle supported' OS, but they may have changed that. Regardless, are you running this on a workstation, or are you trying to install on the system console? if you're on the system console, what desktop environment are you using?

If you're on a workstation, you need X windows software. For Linux, you'll need to start the Xserver without the "--nolisten" option. For Windows, you'll need X emulation software loaded. But you don't say anything about it, so it's hard to give specific advice.

Lastly....you can install Oracle using a text-based installer. See your documentation, or contact Oracle.
