Prior to that, Unix Services were part of OS/390 from its very
beginning. And before that they were present (under a different
name) in the predecessor of OS/390. How many decades does it
take for a service to become "conventional"?
Gil continues to beat this drum - might be getting near time to
listen.
I didn't much care about (or for) OE/OMVS/USS/... when it was
optional.
It has always been a bit of a bastard child in the MVS,OS/390,z/OS...
world
When it became non-optional, it had even less attraction (to me).
Funnily enough, even my customer accounts (generally) are not
enamoured of
it, so it gets used on an "as required" basis.
Even my SAP R3 users use it under sufferance.
I enjoy playing with Linux at home, I can't say the same about USS at
work.
Maybe if they'd implemented it *solely* as Linux in a separate LPAR/VM
rather than grafting it onto MVS I look at it more kindly.
Might have encouraged more customer in this part of the world to look
at
mainframe Linux as an serious option.

No, the point was to be able to run a very unique flavor
of UNIX, one that allows applications to access all the
classic z/OS facilities from the same program that can
take advantage of UNIX capabilities. I know the reviews
are mixed at this point, but IBM has been pretty agressive
in enhancning the facility. I think it's cool you can
run your Web Server on the same software platform as your
z/OS system, that your data server can be the same box
as your web page server.
But, as you point out, there has not been a great move
in that direction. I've written three courses on how to
work with z/OS UNIX and I'm writing some more. But so
far, only the first one has been taught (only about 5
or 6 times).
It may be a case of too little too late. I find very
little training activity right now; what there is is
not z/OS. And very few customers are bothering to
even try it out. Feeling seems to be consistent:
no new mainframe development; no testing of moving
UNIX apps to z/OS; direction is the other way.
Is there anyone out there running a mission critical
application under z/OS UNIX? or even a modest real
application? Anyone looking at doing this?
Silence.
Kind regards,

Steve,
About 6-7 years ago we brought in an IBM team to give a class. It was
at best a so-so class. I was lost after about 3 hours. I gave up after
4 hours and learned it the hard way.
I certainly wish we had known about you back then maybe it would have
helped out a little. The need is out there as I see it, especially for
old types like me. Please keep it available.
One thought you might want to design a course for production support
types. They will need it quite a bit, since most of them came up
through computer operations (at least in my experience).
