Data Guard architecture with multiple primary databases

Sjoerd AalbersNov 21 2012 — edited Nov 21 2012

Hi,

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,
Sjoerd
