Wow! That's quite a few connections. I would say that 10,000 connections
is a lot for ANY database to hold open.
Can this person use connection pooling? Or do they need an actual 10,000
parallel accesses to get things done? If they can't use connection
pooling, or connection pooling only gets them down to 10k to 40k
connections, then that's a huge system. I wouldn't run something that big
on Oracle or Postgresql, I'd use a farm of mainframes running something
like TPF like the airlines do.
