title: How to determine which version of Oracle Client is being used from the server
body: <p>Using Oracle 10g.   ( 10.2.0.4 )</p>
  
  <p>Possibly by looking at either logs or system tables is there a way to determine which version of the oracle client each connection is using.</p>
  
  <p>Our systems initially had 8.1.7 Clients, and then 9.X clients.</p>
  
  <p>We attempted to manually locate all machines that had older clients and upgrade them to  to 10.2 Clients.  </p>
  
  <p>We are seeking a method to audit (from the server) if we were successful in upgrading all of our client machines.</p>
