You might not need a z/OS license for software running inside the penguin, but you would still need licenses for all your other z/OS software, and they would include the CP's that the penguin is running on. I know some z/OS software is charged by usage now, but is all of it? Not only would you need to be able to run Linux under z/OS, you'd also need an IFL that would run z/OS, but only for the purpose of running penguins. We already have that with z/VM, so why bother?

I imagine that running commercial software inside a penguin on z/OS would not require a z/OS licence any more than it does when the penguin's running on z/VM. A penny saved is a penny saved. How well it stacks up depends on lots of variable for which I don't have values, nor an algorithm to assess them. > > /Tom Kern > > John Summerfield wrote: >> >> I imagine it's possible to port Linux to z/OS.
