Configuring Upstream and Downstream Recovery Appliances
This task configures the protection policies for the protected database on the downstream and upstream Recovery Appliance, and then adds the protection policy to the replication server.
If a protection policy that is used, for example, by the CBR122DR database does not exist on the respective Recovery Appliances, these steps create them. The protection policy name does not have to be unique between the downstream and upstream Recovery Appliances.
To prevent a circular references between RAHADR1 and RAHADR2, the protection policy from RAHADR2 is not added to the replication server while the protection policy from RAHADR1 is added. All databases in the protection policy are replicated.
Note: Because RAHADR2 does not normally accept redo from the CDB122DR database, set the unprotected data window parameter is set to 1.25 days to avoid false alerts from occurring if the CDB122DR database is idle.
