Oracle does not have the following attributes:
PDO::ATTR_CONNECTION_STATUS: SQLSTATE[IM001]: Driver does not support this function: driver does not support that attribute
PDO::ATTR_PREFETCH: SQLSTATE[IM001]: Driver does not support this function: driver does not support that attribute
PDO::ATTR_TIMEOUT: SQLSTATE[IM001]: Driver does not support this function: driver does not support that attribute
The rest work fine.
