Re: [PLUG] >32K concurrent processes

Back many years ago, I installed Oracle on my Debian workstation for fun, and I remember the guide had a lot of tweaks.  "ulimit" is one that I can think of, but I don't remember them all.  I'm poking around the internet to see if I can find the oracle guide (although it might not be relevant on newer kernels)

This is old information, but back in the day people who wanted lots and
lots of processes used one of the BSDs to host that server.
