The Question is:
OK, I've searched through the titles for Ask The Wizzard and I can't find it.
Here's my question:
I've installed OpenVMS 7.3 on an Alpha machine. Then I downloaded the VMS
patches and applied them one by one. If the patch said that I needed to
reboot the machine then I rebooted it.
Everything seems to work fine.
Question: Can I apply all of the patches in serial fashion and then reboot the
system just once? Does this in fact work? My tendency is to think that it
would work. The system wouldn't use the new OS files until the system was
rebooted. I think this
should be true because program version information is kept withing the
executable file itself.
I've not tried this yet. The upgrade described was on a non production test
system. The production systems will have to be back up and operational in a
very short period of time.
Cordially,
Dave
The Answer is :
If the ECO kit specifically requires an immediate reboot, you will want
to reboot immediately after installing the ECO kit and before installing
the next ECO kit. Various ECO kits do require a reboot before they
become active -- though given that an immediate reboot is typically not
required by an ECO -- you could conceivably batch together a sequence of
ECO kit applications with fewer system reboots.
ECO kits that require an immediate reboot typically do clearly indicate
this in the release notes. Unfortunately, there is no complete certainty
that there will be unforeseen installation conflicts during the application
of a random sequence of ECO kits (without intervening reboots) -- while
this sequence usually works and it is a sequence that the OpenVMS Wizard
has performed, the OpenVMS Wizard is somewhat hesitant to guarantee that
this installation sequence will work in all cases.
While applying a sequence of ECO kits requiring (non-immediate) reboots,
you can speed the reboot process by using the minimal startup for the
intervening system reboots. The final reboot would be a full startup.
