If the DCS detects that the active cache database has failed, the DCS logs an error to TVI and optionally sends out an email. The System Administrator can promote the standby cache database, to become the active cache database and redirect all Teradata Viewpoint servers to the new active cache database. After the standby server is promoted, the System Administrator must 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 server.
