Step 8: Enabling GUI Access for DBCA – X11 Forwarding

Sometimes, clicking is better than typing—especially when you're setting up a database and prefer a mouse over a terminal. If that sounds like you, let’s get DBCA (Database Configuration Assistant) running with a full graphical interface using MobaXterm.

No extra fuss with Xming or PuTTY—MobaXterm does it all, like a well-trained cat fetching socks (okay, maybe not that magical, but close).

Install X11 on Linux

1) Enable the CodeReady-builder repository

Install the needed packages. This will pull also multiple required dependencies:

Install GUI packages on your Linux server

Install and Launch MobaXterm

• Download from:
  🔗 https://mobaxterm.mobatek.net/download-home-edition.html
• Run MobaXterm (no installation needed for the portable edition)
• In the toolbar, click “Session” → “SSH”

Configure SSH with X11 Forwarding

In the session settings:

• Remote host: your server’s IP or hostname
• Check “Specify username” and enter your Linux username (e.g., oracle or youruser)
• Under X11 Forwarding, make sure “X11-Forwarding” is checked

Then click OK and connect. MobaXterm automatically handles the X server part—no need for a separate tool like Xming!

Steps to Enable Direct SSH Login for the oracle User

• Set a password for the oracle user.

sudo -s

passwd oracle
