Hello all, We're implementing a fairly large J2EE application, I'm estimating around 450,000 concurrent users at high peak. Performing reads and writes and we have a very high performance requirement. I'll be using connection pooling (probably the pooling delivered with Geronimo). I'd like to get an idea of "how big can I go". without running into context switch storms, or hiting some other wall. The design actually calls for multiple databases but I'm trying to get a good idea of the max size / database. (I.e., don't want 50+ database servers if i can avoid it) We'll be on 8.4 (or 8.5) by the time we go live and SLES linux (for now). I don't have hardware yet, basically, we'll purchase enough hardware to handle whatever we need... Is anyone willing to share their max connections and maybe some rough hardware sizing (cpu/mem?).
