changing db settings

I accidently made my db (local host) setting to close to the name of my site.  It is a tester site which I am using to test out this software, but I want to change it nonetheless.  Where do I change the db settings such as host ?

I really have no idea what you are trying to ask, but you can find all the database settings in inc/header.inc.php

I'm thinking he wants to change the name of his sites user database, since he feels it's to similiar to his sites actual name.  Here he'd have to do it in inc/header.inc.php and also go into the SQL Database and change it there.  Not sure if this needs to be dealt with in additional areas.  Give us a break and let us know if this is what you want or is it something else.

thanks.  I am sorry that I was not clear.  I am wanting to know where the configuration settings such as the database, so I can change my db host name, but I think you answered my question.
