Restarting warm servers

Click the Restart Warm Servers button to recycle warm servers in all server manager pools without shutting down the server manager. This is useful for updating cached values on a warm server. The Restart Warm Servers button can be found in the Teamcenter Management Console under the Operations link. Example In a four-tier configuration, Host A and Host B use a common Teamcenter database. Changes made to preferences with a protection scope of Site on Host A affect all existing Teamcenter server processes running on Host A. Because Host B caches such preferences when it starts, the changes to these preferences are not received by Host B if it was running when the changes are made through Host A. The changes are not immediately received by Host B. In a four-tier environment, the server manager can be configured with additional warm servers, ready for use by the next user to log on. Warm servers cache preferences when they are started. If warm servers are configured, and Host B logs off and then logs on through a warm server, Host B still does not receive the preference changes because the warm server cached the preference settings when it started. To ensure that all hosts receive the latest information at logon, use the Restart Warm Servers button. This operation stops and restarts all warm servers, ensuring each warm server receives the latest preference settings. If you use this functionality to restart most (or all) the warm servers at your site, this task should be performed with very few users on the system. Otherwise, there is a risk that no warm servers are available during the short time it takes to recycle the servers. Example The server manager is configured to support 100 users during 08:00 to 17:00. At 07:55, there are no users on the system; therefore, there are 100 warm servers available. Choosing to recycle all 100 servers at 07:55, in order to refresh cached server values, may not allow sufficient time for the servers to restart by 08:00. Any users attempting to log on before the servers have restarted receive a message that no server is available.
