KIIT Student here, hates Windows to the point where I refuse to even run it via dualboot or VM now. Below is a somewhat guide to install OracleDB xe 11 on (Arch) Linux.
Sadly, Oracle no longer officially hosts v11 of this product, so I had to look for alternatives. Our college themselves keep a Windows version copy of original OracleDB, but it's not usable on linux, even if I try it on Wine.
The hardest part was to find the original .zip file, and I finally found it at here
Archlinux hosts an AUR package oracle-xe-11g, which you can install via AUR Helpers like yay or paru.
