Hi
Probably this question might sound crazy but i am not able to find the answer of it so posting it here.

What do we mean by Mainframes on UNIX?
What do we mean by Mainframes on LINUX?

Is there any difference between them?

I have seen people using UNIX along with mainframes but not Linux. you code and do all the tasks in a UNIX environment as compared to the emulator/simulator which runs on windows and which connects to mainframe. Neutral
Linux is free where as UNIX is not.

Well, 'mainframe' is the 'big iron' computer and Unix/Linux are operating systems that can run on the mainframe. Yes, I read somewhere, probably IBM in-house (so a few years ago now), that IBM had ported Linux to whatever was the mainframe then - 3090?

I'd say: unix on mainframe. Ever since MVS in POSIX compatible it may call itself unix. This is a special 'mode' in MVS and enables you to install WebSphere or SAP/R3 or Lotus Notes and so on.
And there is linux/390. Linux can run in an LPAR or as a VM guest O.S.
