Configuring load balancer timeouts

If you use a third-party load balancer, ensure its timeout setting values are equal to or greater than the timeout settings for Teamcenter as entered in the Web Application Manager Session Timeout box. This indicates how many minutes of inactivity are permitted before the web server terminates the session on the web server. From the Modify Web Application dialog box, click Modify Web Application Information. The Web Application Manager displays the Modify Web Application Information dialog box for the Session Timeout box. The Teamcenter web tier and Teamcenter Security Services Login Service maintain client session information. When deployed behind a load balancer, it is important that all requests from a given client are routed to the same back-end web tier or Login Service instance. Ensure that you set the load balancer's session timeout interval to a value equal to or greater than the Teamcenter session timeout values. Also, load balancers typically have a stickiness or affinity setting, and this must be set as well in the load balancer configuration for these Teamcenter web applications. Otherwise, the load balancer timeout eclipses the Teamcenter timeout and can lead to apparently random and unexpected behavior as the load balancer switches between active web application instances.
