Symptoms

In Meter Data Management 2.1.0.2 / Oracle Utilities Application Framework 4.2.0.3 IWS (Internal Web Services) don't really use session and weblogic defaults to keep sessions open for at least 1 hour after being inactive. With webservice calls, this means that weblogic is hanging on to session data for each request for at least 1 hour. In a high load environment, this not only results in increased memory but when the sessions are finally reclaimed, the garbage collector can render the web server unusable for a periods of time.

This can be controlled via two Weblogic session management configuration values.

• Session timeout (timeout-secs) is the amount of time that must elapse before an inactive session can be reclaimed.
• Session invalidation (invalidation-interval-secs) is how frequently weblogic runs the session reclamation code.

Unless the IWS configuration has been manually edited, navigate to Deployments -> Webservices -> Configuration in the Weblogic console and note that the Session Timeout is 3600 seconds.
