Ed, if you really have nothing better to do than look every half hour
for additional HIPER maintenance, you really need a life :) Yesterday
is current enough for me.

If that is what is good for you fine, personally I would expect no
less from anyone. I would also expect to monitor all new hipers for
at least a week (or two) after maintenance goes on. I do have a life
but maintenance is part of it and if you had a baby would you leave
it out on the front lawn because you have checked the neighborhood
for wolves (and found none) ?
When my "baby" goes into production I am in proactive mode not
reactive. I don't wait for the wolf to come to my street corner. i
also monitor logrec and system dumps all the time. That is how you
find things that are in the process of breaking.
Saying that, not all hipers are really important. If there is one out
there for a component we don't use I don't rush to put it on, the
next round of IPL's is fine. But if a hiper PTF came out got lets say
VSAM it would go on as fast as I can schedule it (or sooner if it
breaks something).
This was a lesson learned by me after 5 years of MVS sysproging I
have constantly refined it over the years. Yes MVS has gotten better
but lessons learned, it is almost always better to be safe than have
something broke at 2AM. We don't have (anymore) mega ptf tapes thanks
to better testing by IBM but coders are not perfect and mistakes do
happen.
