However, I must not be configuring bigdump.php correctly because I keep getting this error:
Database connection failed due to No connection could be made because the target machine actively refused it.
Here's my database configuration in bigdump.php.
$db_server = 'localhost'; $db_name = 'testdb'; $db_username = 'drupaluser'; $db_password = '';
Do I have to edit something in Acquia Dev Desktop to allow connections?
