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 Xming.

Login as root user and install the needed packages. This will pull also multiple required dependencies on Linux,

dnf config-manager --enable ol8_codeready_builder

dnf install xorg-x11-apps xorg-x11-xauth

dnf install xorg-x11-apps xorg-x11-xauth

Login as opc user:

type: xauth list

Allow login for the oracle user in SSH config

Switch to the oracle user:

Add entire output using “xauth add” command:

Allow login for the oracle user in SSH config

export DISPLAY=localhost:10
