title: How to determine if a table has been accessed in the last month?
body: <p>In Oracle 10, is it possible to determine when the last time a table was accessed?</p>
  
  <p>According to <a href="http://www.dba-oracle.com/t_monitoring_table_usage.htm" rel="nofollow noreferrer">this article</a> the data is there, but I'm not sure whether this is reset whenever the server is restarted, nor how to actually get the access information.</p>
  
  <p>We're actually trying to determine what tables are no longer used.</p>
