well i am autoloading the database core library

Code:

$autoload['core'] = array('database');

is that code right and is there anything else i have to do yet, i have also setup the database file.

Code:

$db['default']['hostname'] = "hostname";
$db['default']['username'] = "username";
$db['default']['password'] = "password";
$db['default']['database'] = "gf_news1";
$db['default']['dbdriver'] = "mysql";
$db['default']['dbprefix'] = "";
$db['default']['pconnect'] = TRUE;
$db['default']['db_debug'] = TRUE;
$db['default']['cache_on'] = FALSE;
$db['default']['cachedir'] = "";
$db['default']['char_set'] = "utf8";
$db['default']['dbcollat'] = "utf8_general_ci";
