It's really an Oracle question, I think.  The setting in php.ini for
limiting MySQL is, I think, not *quite* the same as the setting in MySQL's
/etc/my.conf that limits how many MySQL will accept...  Not sure on that
though.

Still, it's probably one of Oracles two zillion environment variables.

I have to assume that Oracle can do that -- for the price you paid it had
better :-)

Make sure you have a few spare connections that you never use.  When you
need to do something in a panic from the shell and all the connections are
already tied up, it's not pretty...

Your code-base had better be ready for the failed connections...  I mean, if
you didn't write good solid error-checking in all 2000 connection points,
you're going to see a lot of applications dying horribly...
