Question

I’m trying to get the memcache query/result cache working with Oracle. It works flawlessly against mysql (verified with memcached console: ./memcached -u nobody -m 40 -vv). Here’s what’s in web/index.php:

$servers = array(
    'host' => 'localhost',
    'port' => 11211,
    'persistent' => false
);

$cacheDriver = new Doctrine_Cache_Memcache(array(
    'servers' => $servers,
    'compression' => false,
    'prefix' => 'qc-')
);
$manager = Doctrine_Manager::getInstance();
$manager->setAttribute(Doctrine::ATTR_QUERY_CACHE, $cacheDriver);
$manager->setAttribute(Doctrine::ATTR_RESULT_CACHE, $cacheDriver);
$manager->setAttribute(Doctrine_Core::ATTR_RESULT_CACHE_LIFESPAN, 3600);

This works as supposed against MySQL but fails with following message at the first location where i use ->useResultCache(true):

Result Cache driver not initialized.

Does anyone have clue about what’s happening and/or if there’s additional configuration needed to get it working with Oracle DB backend?

Thanks.

you should try to set those manager attributes inside your YOUR_APPConfiguration class like explained here : http://www.funstaff.ch/2009/03/19/le-cache-de-resultat-avec-doctrine

class frontendConfiguration extends sfApplicationConfiguration
{
  public function configureDoctrine(Doctrine_Manager $manager)
  {
    $servers = array(
        'host' => 'localhost',
        'port' => 11211,
        'persistent' => false
    );

    $cacheDriver = new Doctrine_Cache_Memcache(array(
        'servers' => $servers,
        'compression' => false,
        'prefix' => 'qc-')
    );
    $manager->setAttribute(Doctrine_Core::ATTR_QUERY_CACHE, $cacheDriver);
    $manager->setAttribute(Doctrine_Core::ATTR_QUERY_CACHE_LIFESPAN, 3600);
    $manager->setAttribute(Doctrine_Core::ATTR_RESULT_CACHE, $cacheDriver);
    $manager->setAttribute(Doctrine_Core::ATTR_RESULT_CACHE_LIFESPAN, 3600);
  }
}
