      When I am trying to connect to Oracle instance with another charset then specified in my environment variable NLS_LANG I got an error.

      $connectionOptions['oracle'] = array(
          'driver' => 'oci8',
          'dbname' => 'BOOK',
          'user' => 'doctrine',
          'password' => 'doctrine',
          'charset' => 'AL32UTF8',
      $em = EntityManager::create($connectionOptions['oracle'], $config, $evm);

      Produce error messages:

      PHP Warning: oci_error() expects parameter 1 to be resource, boolean given in /www/test/doctrine2/vendor/dbal/lib/Doctrine/DBAL/Driver/OCI8/OCI8Connection.php on line 149
      PHP Fatal error: Uncaught exception 'Doctrine\DBAL\Driver\OCI8\OCI8Exception' in /www/test/doctrine2/vendor/dbal/lib/Doctrine/DBAL/Driver/OCI8/OCI8Connection.php:42

      There is bug in OCI8Connection::errorInfo() and ::errorCode(). When oci_connect failed, it returns a boolean - false. but oci_error() accepts only resource as parameter. Therefor it is neccessary to check, whether $this->_dbh is resource.

      When I've fixed the error handling, I've got the right error, why I couldn't connect to Oracle:

      PHP Fatal error: Uncaught exception 'Doctrine\DBAL\Driver\OCI8\OCI8Exception' with message 'ORA-12154: TNS:could not resolve the connect identifier specified' in /www/test/doctrine2/vendor/dbal/lib/Doctrine/DBAL/Driver/OCI8/OCI8Exception.php:28

      That's because oci_connect accepts as connection string only TNS name, or Oracle Connection string. But ;charset=* in TNS name or connection string is invalid. oci_connect has 4th parameter charset for that purpose.
