I'm curious, have you looked at IBM's System z Academic Initiative program?

It's been active for years, offers online training, classes at hundreds
of colleges/universities, certifications, etc. It seems to get positive
reviews. For z/Motivat
I turned 30 earlier this year, and I am a sysadmin since my
twenties... I think the problem is that you can buy a computer to run
Solaris, Windows, MacOS, MS-DOS, but you can't buy a computer to run
zVM. I know some Linux admins as old as me, and they are very
competent doing a reliable job, workin

Perhaps, but Linux more than makes up for that :))

Same way we got incented. Management makes a commitment to hire, train,
and compensate zVM people. Do you see that happening in today's world of
commodity hardware, open source software, and lowest common denominator
application development?

Thanks Sirs Richard, John, DavidB, Rob, DavidD, Bear, Thomas, Patrick and
Madame Marcy -
I appreciate your input very much! I believe it has helped decide in
favor implementing ntpd on Linux guests in this particular instance.
A special thanks to Rob for his presentation which helped myself and
I'd suspect that just running ntpd would be a preferably option here.
Otherwise, you will get a cron awakened activity / network peak as
dozens or hundreds of servers all wake up and try to sync their time.
ntpd really is a very low impact service to run, both in terms of
network and server resour
When we had linux on Z, we ran the ntpdate program once per day (before start of
business). On our current ESX and Oracle Virtualization (xen), we need to run
it every hour.

Running NTP everywhere wakes every guest up periodically, so you waste a fair
amount of cycles waking up to do nothing for most guests.
The clocks in Linux guests do drift slightly (even if the HW is synced to STP)
-- it's order of tenths of microseconds, but it does lose a little (barely

Recommendation leans toward "no", but is not firm.
Back before we had STP, I used to say "no", then changed my story to
"yes, run it". Lately not so sure.
6 or 7 or more years ago, the point was ... dozens or hundreds of
Linux guests ... do you want them all running NTP? At first, "we"
said no
Was having a conversation today about running Linux on System z and whether
it needed to run an NTP client -- the statement being STP is used to keep
the mainframe time in synch, so why run NTP on a Linux guest - the system
time is correct. My understanding is that Linux maintains it's own clock
