title: MySQL table_cache refuses to change value
body: <p>For some really weird reason, both of my <code>table_cache</code>  as well as <code>query_cache_limit</code> values in the <code>my.cnf</code> file refuses to change value even though I've modified them.</p>
  
  <p>e.g in mysqltuner the following recommendation is shown:</p>
  
  <pre><code>query_cache_limit (&gt; 1M, or use smaller result sets)
  table_cache (&gt; 400)
  </code></pre>
  
  <p>However in the my.cnf file I have:</p>
  
  <pre><code>query-cache-limit              = 8G
  table-open-cache               = 2048
  </code></pre>
  
  <p>I've restarted mysql, apache and the server yet the values refuse to be updated. I'm using the Percona 5.5 drop in mysql server.</p>
  
  <p>Any tips or suggestions are really welcome.</p>
  
  <p>Thanks</p>
