This graphic shows an active standby replication scheme on a local site that autorefreshes updates into replicated read-only cache groups from a primary Oracle database that is part of an Active Data Guard configuration. The standby Oracle database is located on a remote site. In addition, the TimesTen replication scheme includes a read-only subscriber that was created with the -ADG option and so includes cache tables and is also located on the same remote site as the standby Oracle database.
