MaxClients in httpd.conf reduces your total server performance in case you
have not only db-actions but also images and plain files ...
if you use something other than ocilogon you open a persistant link that
might not be closed. (try using ocilogon instead of eg ociplogon)
close every connection with ocilogoff
If you are running heavy traffic try to configure your NET8 Listener to work
as MTS. This does not create and destroy a process every time you query the
server, but delivers all incoming queries to some worlking-server-processes,
starting and stopping them when needed, just like apache handles its childs.
Increase the Global System Area by incresing the Shared Pool Size of your DB
: this will inspire the db to consume more caching ram. On the other site
check the ram consumption of oracle... maybe it swaps!
If you want to limit your PHP-Scripts connections there is the problem with
the synchronisation of the counter: sessions, a file, shared memory/IPC
System V. It all doesn't sound very satisfing.
Maybe you can place your db-phpscripts into a virtual host or another apache
and configure that with a lower maxCLients directive, but this will simply
lock out your visitors not giving you a chance to intercept the error
Another Idea: can you limit the number of concurrent sessions created by one
DB-User ? if possible you could assign your scripts a special user and
therefore allowing connections with higher priority from e.g. your admin
