Hi, I am operating a web server with various vhosts.
Some use php/mysql, some plain html.
For performance reasons I decided to built apache with php (built with
mysql)
But now, I have to put online a site using PHP/Oracle.
If I compile a new apache/php with mysql AND oracle I'm afraid to get
something big that will be used only for one site.
I was wondering : is there a way to tell apache to load modules only when
needed (something like putting AddModule/LoadModules directives in
<Virtualhost>) or any solution to avoid to launch a big process including
php and all its lib just for a simple html page.

Maybe someone had this type of problem and found a clever way to handle it.

Thank you for your answers

Actually, this isn't a big problem. But if you want to change which
modules get loaded into php, you need to edit the php.ini file, not the
apache httpd.conf file, since the oracle/postgres/mysql/db2 etc. modules
are loaded into libphp.so by direction from php.ini.

In terms of executable size, you're only talking a few hundred k at most
to add a module for another database (usually less than that.) while php
4s optimizations use about 4 to 10 times the memory of the size of your
scripts, plus a fair bit of storage for all the data your script is
manupulating.

Don't worry that much about the size of the executable; it's not as if there
are actually separate RAM copies of it.

I think you'll find that any solution involving selectively making various
database drivers available will actually be more resource-intensive. Just go
ahead and build MySQL and Oracle into it.
