title: Oracle measuring execution time stored procedure
body: <p>I would like to measure the execution time of a stored procedure in Oracle. I have learned about the technique of writing an entry in a temporary logging table at the start and the end but am unable to use this technique.</p>
  
  <p>Can you refer me to an open source/free tool with which I'm able to do this?</p>
  
  <p>Thanks!</p>
