oci8 syntax in DB.php ?

Hey guys,

Seem to be having a bit of a problem using oracle + DB.php.

I can connect to the database with no problems using OCILogon, but when
using this:

$db = DB::connect( "oci8://$dbuser:$dbpass@$dbname/$dbhost" );

Which I believe is wrong, or

$db = DB::connect( "oci8://$dbuser:$dbpass@$dbname" );

Is what I think it should be. Regardless they both don't work.

The error that I am getting back is:

Fatal error: Call to undefined function: ocilogon() in DB/oci8.php on line
86


Any ideas ?

Thanks,

John
