title: Getting symfony query and result cache to work against oracle 11g
body: <p>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:</p>
  
  <pre><code>$servers = array(
      'host' =&gt; 'localhost',
      'port' =&gt; 11211,
      'persistent' =&gt; false
  );
  
  $cacheDriver = new Doctrine_Cache_Memcache(array(
      'servers' =&gt; $servers,
      'compression' =&gt; false,
      'prefix' =&gt; 'qc-')
  );
  $manager = Doctrine_Manager::getInstance();
  $manager-&gt;setAttribute(Doctrine::ATTR_QUERY_CACHE, $cacheDriver);
  $manager-&gt;setAttribute(Doctrine::ATTR_RESULT_CACHE, $cacheDriver);
  $manager-&gt;setAttribute(Doctrine_Core::ATTR_RESULT_CACHE_LIFESPAN, 3600);
  </code></pre>
  
  <p>This works as supposed against MySQL but fails with following message at the first location where i use ->useResultCache(true):</p>
  
  <blockquote>
    <p>Result Cache driver not initialized.</p>
  </blockquote>
  
  <p>Does anyone have clue about what's happening and/or if there's additional configuration needed to get it working with Oracle DB backend?</p>
  
  <p>Thanks.</p>
