Hi All,I've been running Apache 2.2.9 / PHP 5.2.6 / Win XP SP3 with 3 named vhosts for about a year with no real problems. Recently I added a fourth vhost to run a Drupal site. This involved adding mySQL, and it all worked after the usual few setup iterations. After the site was running happily for a couple of weeks, I revisited the setup and removed 'DBDPersist Off' from the vhost. After I did this, I get the following messages in the error log at startup, even though the site subsequently appears to work correctly and there are no 'runtime' errors:[Sat Aug 15 12:25:22 2009] [error] (OS 126)The specified module could not be found. : DBD: mod_dbd not compatible with APR in get_driver [Sat Aug 15 12:25:22 2009] [error] (OS 126)The specified module could not be found. : DBD: failed to initialise
That means it's failing to load the database driver, and the error is one that mod_dbd doesn't know about, so it can't report it correctly to you. That's a bug, albeit a minor one (the error message should be better). Since Windows error 126 means nothing to me (it would be great if you or anyone could say), it would be helpful to be able to diagnose exactly why it can't load the mysql driver. Do you in fact have the MySQL driver installed? The fact your application works presumably means it isn't using DBD, and PHP is connecting to MySQL using a pre-DBD method. So you should be able to remove the DBD configuration. If I'm wrong about that, then something strange is going on and will need investigating! As regards your questions, it's up to an application whether it uses DBD or does its own thing. WAMP is neither more nor less likely to use it than Unix/Linux based platforms. For a single application it doesn't usually matter much, but if you have several separate MySQL applications that don't use DBD then you're placing a lot of extra load on your server. -- Nick Kew --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
