  <p>In my database configurations I have kept <strong>PCONNECT to FALSE</strong> .</p>
  
  <p>Now My Structure is as follow:</p>
  
  <p>I have a base controller <strong>MY_Controller</strong> which extends to <strong>CI_Controller</strong>.</p>
  
  <p>Then I have a <strong>Customer_Controller</strong> which extends to MY_Controller.</p>
  
  <p>In Customer_Controller I load my secondary database. And this Customer_Controller lives in libraries folder. </p>
