    Data Guard architecture with multiple primary databases

    Sjoerd Aalbers

      We are designing the following data guard configuration:

      - DB version 11gR2
      - Multiple primary databases and primary databases are dependent on each other e.g. client data from DB1 (MDM) is replicated to DB2
      - Each primary database has a standby database
      - Delayed apply redo log

      How do we guarantee consistency among all standby databases in case of a fail over? Any support by Data Guard to guarantee consistency among standby databases?

      Best regards,
