Yes, I get that. But why would it be better for the scheduler to start
up database servers on multiple hosts and allow them to compete for a
lock, rather than pick one host to start the database and start one
instance? The former is what JD is suggesting (adapted to your
proposal; as far as I can tell), while I suggest that the latter is
probably a better approach if it's possible, and it usually is.
