John, there is at least one serious financial implication when running all (or any part of) OS/390, so please be aware of this. Please note that, as always here, I do not speak in an official capacity for IBM.
One of the (very few!) requirements for enjoying (or continuing to enjoy) any sub-capacity IBM software pricing is that *all* OS/390 must be completely off the machine(s) in question. [Furthermore, all z/OS on the machine(s) must be IPLed in 64-bit mode.] Said another way, when you IPL OS/390 on your z990 -- 1 VM or 20, inside or outside z/VM, it doesn't matter -- you must have an OS/390 license (plus licenses for the other software running on OS/390), and *all* the OS/390 *and* z/OS *and* middleware products running on that z990 must now be paid at full capacity, including "One-Time Charge" products. The whole box zooms up to full capacity charges, instantly and irrevocably for the month(s) that you're running OS/390. Here's one reference to those terms (though your VWLC contract is controlling -- and says much the same no doubt): http://www-03.ibm.com/systems/z/resources/swprice/subcap/zos.html Quoting: "When you are running z/OS in 64-bit mode and are no longer running OS/390 on your System z server, you have the option to pay the charges for your eligible software on a sub-capacity basis." In a large majority of cases the loss of sub-capacity licensing is financially unattractive, particularly on a sustained basis. At a minimum, I would strongly recommend upgrading the OS/390 workload quickly to z/OS. And talk to your IBM rep *before* you IPL any licensed software that you are not currently licensing and/or that you're not paying at the correct capacity. Or, at the very least, shut down now and talk to your IBM rep now if you are unlicensed and/or not paying full capacity for all licensed software on your z990. Sorry if that's bad news, but I'm personally familiar with a customer who was not aware of this and which owed IBM (and perhaps other vendors) a significant amount of money. They were not happy. Now, I'm sure someone is going to say, "Yes, but, here's why my company needs to run OS/390 for X months...." (or whatever). Simple: talk to your IBM rep *first*, present the business case, and get an approval and price! IBM (and presumably most vendors) take a very dim view otherwise, and their hands are tied. It then becomes a contract enforcement/accounts receivable exercise, not subject to discretion.
