Thanks for the reply. Yours seems to be the best so far. I wanted to try and figure the cost of setting up multiple z/OS machines in a fairly quick manner.
As I remember the old VM/BSEPP you could run as many operating systems as you wanted under VM and be charged for only 1 copy of the operating system. That doesn’t seem to be the case using LPAR’s . It seems that we get billed for running z/os on Lpar 1 and Lpar 2. They gather the amount from the SMF records that are produced. That’s why I was wondering if I would get billed for multiple z/os virtual machines under z/VM.

And we pay the VSE license for the total capacity of the machine. I don’t think you can say that VM is better than LPAR as a general statement. In some cases VM definitely is better, and in others, LPAR is the winner. Do you need to create new z/OS instances on short notice for a brief testing period? z/VM is a clear winner. Do you need every last CPU cycle for your production z/OS? LPAR is better here. Do you need to frequently shift resources around between your LPARs? z/VM might make your life easier. Is your hardware environment fairly static? Could be better to stay with LPARs. Are you thinking of running Linux on your mainframe? You will almost certainly want to run z/VM then. z/VM brings you unmatched flexibility, but at a cost of some CPU cycles and money. If you have large numbers of LPARs though, it can reduce the complexity of your configuration, and allow better sharing of your resources. Perhaps if you expand on what you hope to achieve, we can provide more targeted responses.

When we set up and lpar with an operating environment such as MVS, we get software charges for both lpars from IBM. Third party vendors don’t seem to care if it’s on the same machine (Most don’t) since they charge for the full mip rate of the machine regardless of whether it’s utilized or not. Long ago, about 30 years I had a VM shop and we ran multiple instances of OS/VS1, MVS, etc, but were only charged for on license of software product. Is this still the case? Is it better to use VM instead of LPAR? All comments appreciated.
