Restore points created on the primary database are propagated to the standby sites, so that they are available even after a failover operation.
Business Benefit: Normal restore points or guaranteed restore points are defined at the primary site to enable fast point-in-time recovery in the event of logical corruptions. These restore points are stored in the control file. In the event of a failover, the standby database becomes the primary database. However, the restore point information is lost. Propagating restore points from the primary to the standby simplifies the complexity of the restore and recovery process after a failover because the standby database is updated with the restore points created on the primary database.
