The Oracle9i Data Guard architecture incorporates the following items:
Primary Database - A production database that is used to create standby databases. The archive logs from the primary database are transfered and applied to standby databases. Each standby can only be associated with a single primary database, but a single primary database can be associated with multiple standby databases.
Standby Database - A replica of the primary database.
Log Transport Services - Control the automatic transfer of archive redo log files from the primary database to one or more standby destinations.
Network Configuration - The primary database is connected to one or more standby databases using Oracle Net.
