If the active Teradata Viewpoint server fails, the standby DCS detects that the active DCS and cache database are both down and logs an error to TVI and optionally sends out an email alert. The System Administrator can promote the standby cache database to the active cache database and send a notification to all Teradata Viewpoint portals so that they are automatically redirected to the new active cache database.
After the standby cache database is promoted, the System Administrator needs to set up a new standby cache database.
If the cluster is set up using the advanced configuration, stop the Teradata Viewpoint portal on the new active cache database server so that it continues to run on a dedicated machine.
