We can leave "z/OS" out of this discussion, because it isn't germane.
Insert (machine-licensed) "Oracle Database," for example, and it'll be the
same answer. Software which is licensed to a particular machine is for that
machine. If you want to run it on another machine, you need a license for
that machine. (With narrow exceptions if they're permitted in the license
agreement, such as disaster recovery. There is certain permitted use of the
ISPF Workstation Agent, to pick another example.)

The technical means of copying the file(s) don't matter. Floppy disk, NFS,
BitTorrent... doesn't matter. Whole product or one file... doesn't matter.
The license agreement doesn't permit you to do any of those things without
a license for the target machine.

If you obtain the particular file in question from the vendor through a
vendor-authorized avenue, with a valid license agreement for the target
machine, then you're fine. Kirk described a vendor download path which
looks OK.

Thank goodness. At least one of my customers was not so prudent. :-(

If you're in doubt about permitted use, just ask the vendor first. I don't
speak for IBM, but in my experience at least IBM is quite reasonable when
handling such questions and situations.

I'm sorry to hear about the corporate politics, with one IT group
apparently determined to manage critical assets inefficiently, knowingly,
to the apparent detriment of the company's own business interests. I have
occasionally seen such behaviors. There are some ways to handle them.

Someone else was asking why some customers don't adopt sub-capacity
software licensing and Enterprise License Agreements. Darned if I know! I
suppose there are exceptions to everything, but, as a general rule, it's
just smart financial practice.

I'm very happy to advise my customers on how to run their mainframe-related
assets at peak efficiency, but on one condition: that I also get a
reasonably serious opportunity to advise them on how to manage *all*
business costs more efficiently. I find if they're not doing well in the
former category, they're also probably not managing well generally.
