Question

我尝试连接到CI中的多个MySQL数据库如果与第一个DB的连接失败，我尝试连接到第二个，
我在CI论坛中使用此代码： http://ellislab.com/forums/viewthread/224522/#1030449

$db_obj = $this->database->load('xxx',TRUE);
  $connected = $db_obj->initialize();
  if (!$connected) {
     $db_obj = $this->database->load('yyy',TRUE);
  }

它在本地主机上工作正常，它尝试连接到第一个DB并失败，然后直接连接到第二个DB（没有任何长时间 - 透明度）
但
当我将代码移动到在线服务器时，尝试连接到第一个DB需要很长时间，然后（在此超时之后）它尝试连接第二个DB并成功了我怎样才能删除这个等待时间？我需要它直接尝试连接到失败案例中的其他数据库

我的数据库配置如下：

$db['DB1']['hostname'] = '1.1.1.1';
$db['DB1']['username'] = 'test';
$db['DB1']['password'] = '123456';
$db['DB1']['database'] = 'db1';
$db['DB1']['dbdriver'] = 'mysql';
$db['DB1']['dbprefix'] = '';
$db['DB1']['pconnect'] = TRUE;
$db['DB1']['db_debug'] = FALSE;
$db['DB1']['cache_on'] = FALSE;
$db['DB1']['cachedir'] = '';
$db['DB1']['char_set'] = 'utf8';
$db['DB1']['dbcollat'] = 'utf8_general_ci';
$db['DB1']['swap_pre'] = '';
$db['DB1']['autoinit'] = FALSE;
$db['DB1']['stricton'] = FALSE;


$db['DB2']['hostname'] = '1.1.1.1';
$db['DB2']['username'] = 'test';
$db['DB2']['password'] = '123456';
$db['DB2']['database'] = 'db2';
$db['DB2']['dbdriver'] = 'mysql';
$db['DB2']['dbprefix'] = '';
$db['DB2']['pconnect'] = TRUE;
$db['DB2']['db_debug'] = FALSE;
$db['DB2']['cache_on'] = FALSE;
$db['DB2']['cachedir'] = '';
$db['DB2']['char_set'] = 'utf8';
$db['DB2']['dbcollat'] = 'utf8_general_ci';
$db['DB2']['swap_pre'] = '';
$db['DB2']['autoinit'] = FALSE;
$db['DB2']['stricton'] = FALSE;

非常感谢！

CodeIgniter检查与多个数据库的连接需要很长时间
