Have you tried using the IP address where the database is residing on?

 

Just use the url given by the hostingparty. For instance: mysql41.yourhosting.com

 

are these sites on the same server?

 

Yes...I have 5GB reseller package...

 

you set up the database for one site

Then for each script use on each site:

$db_server = "localhost";
$dbname= 'database_name';
$db_user = 'database_user';
$dbpass = 'database_pass';

Those settings should be the same for all sites and only one database should exist.
