Decent UPS equipment usually comes with a serial connection and
software. You can tell it to run a script when the UPS signals that it's
switched to internal power, typically this will page someone and might
even run an orderly shutdown. Even though a single UPS can support many
machines, it will generally only be able to signal one by itself.
A few years ago, I was working for an ISP, we wrote some simple scripts
that would enable the machine connected to the UPS to email other
machines when the power failed, as Unix lets you direct an email to a
program rather than a mailbox. These machines would then do whatever was
necessary to bring their applications down cleanly.
A UPS will give you plenty of warning before it is actually exhausted,
there is ample time to shut down Oracle, but I doubt there would be
enough time to actually run a hot or cold backup onto tape.
