I used to work on a McDonnell Douglass (PICK) machine, that had a small
battery built in
that in case of a power failure, would, immediately write the contents of
memory to a section
of disk, then do a shutdown, upon power-up, if it saw info in that area of
disk, it would
reload memory, and continue on, in effect making the system act as if
nothing ever happened.
Is it possible to setup unix (or tru64) to do the above? Have a UPS signal a
power failure
then for the most part halt the system, writing memory out, then on power-up
do the reverse
of would the time gap really mess with things?
Having the UPS shutdown a system is great to control corruption, but it
would be even better
if on power restoration, the system could continue (say if it was in the
middle of doing nightly
updates when the power went down) without human intervention.
