What are different operating systems in mainframes?

Post by Priya »

Hi,

Are there any other operating system that supports mainframes other than zOS, OS/390 and MVS?

And are there any differences among them, if any?

Thanks,

MVS was succeeded by OS/390 which in turn was succeeded by z/OS. All three operate the same way and are more similar than different.

TPF (z/TPF?), z/VM, z/VSE, z/LINUX are other current mainframe operating systems for IBM hardware. Mainframe systems other than IBM exist and since their architecture is so different so are the operating systems.
