Hi, my webapp is a MVC and my database is Oracle 11g. My models extends Phalcon\Mvc\Model, so, uses Phalcon\Db\Adapter\Pdo\Oracle. But PDO_OCI is a experimental extension (https://php.net/manual/en/ref.pdo-oci.php) and my client don't allows this installation in your server. I wonder if anybody have a Oracle Adapter was developed with oci8 instead of pdo. Best regards.
