Not sure about 600, but i have heard of cases where the connection pool size was so large, it brought down the DB server when the pools were intialized.

[SURVEY] How many connections are apache.org in your pool? Hi all, I've been studying a few large enterprise applications and have noticed an interesting trend... many of these apps have HUNDREDS of connections (like 600) available or even open in their connection pools... Survey Questions: 1. How many connections do you have available in your pool? 2. And if you know, how many CPU cores are available on your database server (or cluster)? 3. If you have 2x or 3x more connections than you do CPUs, do you have a reason that you could share? Cheers, Clinton
