Re: Minimal bootup for Alpha and VAX
that sure is not too bad, is it?
Compare:
I once attended a "technical" session on high uptime for a bank's (IBM) computer.
It was announced as "how to get to 100% uptime."
During the lecture it turned out it was intended to mean:
(drumsolo growing to crescendo)
... always running between 7:30 am & 20:00 pm on weekdays, !!!!!
and just about the hardest effort they made was Database shutdown & backup, and "DAYLY" IPL (IBM parlance for reboot) in scheduled off-hours shifts, and arranging for maintenance to be done, not on weekdays but on weekends.
And most people in the audience had systems more or less comparable to yours!
Well, the Q&A turned out a little embarassing, and a concensus on the advice NEVER to call such system uptimes 100% in a VMS audience..
Maybe a lot of the effect is in the eye of the beholder.
fwiw,
Cheers.
Have one on me.

Re: Minimal bootup for Alpha and VAX
well back to the topic of time changes ;-),
you might want to consult the FAQ at
http://h71000.www7.hp.com/wizard/faq/vmsfaq_004.html#time8
in particular section 4.3.2. This might be to late to implement for this Sunday, but spring will be here soon again ;-)
Drifting the time has its own issues (esp. if you need to synch your time with external applications records), but might beat shutting down the system/app completely.
Greetings, Martin

Re: Minimal bootup for Alpha and VAX
"For those areas which switch between daylight savings time (DST) and standard time, the [NTP] time value is not drifted. The time is adjusted by the entire interval. This procedure is inherent in the definition of the switch between DST and standard time."
That is why, NTP is stopped before a time change and restarted after.
