title: Run oracle procedure automatically every hour
body: <p>i have created a simple procedure in oracle. pseudo code is </p>
  
  <pre><code>CREATE OR REPLACE
   procedure  update_summary
   begin
    delete from summary table;
    make different calculations from different tables, insert values row by row in 
    summary table;
   end;
  </code></pre>
  
  <p>I want this procedure to run automatically every hour since if i call it from front end of my application, its quiet time-hungry and user think that page has hanged. help would be highly appreciated.</p>
