When Recovery Appliance replication is configured, the protected database sends backups to the upstream Recovery Appliance. The upstream Recovery Appliance then forwards these backups to the downstream Recovery Appliance. In the event of a failure, if the upstream Recovery Appliance is unavailable, then you can perform restore operations using the downstream Recovery Appliance.

Use the following high-level steps to restore a protected database directly from a downstream Recovery Appliance:

1. Create an Oracle wallet that contains the credentials of the VPC user with which the protected database will authenticate with the downstream Recovery Appliance.

   See Also:

   "Creating an Oracle Wallet on the Protected Database"

   Note:

   The protected database need not be explicitly added to or registered with the downstream Recovery Appliance before performing restore operations. When replication is configured between the upstream and downstream Recovery Appliance, the protected databases enrolled with the upstream Recovery Appliance are registered with the downstream Recovery Appliance.

2. Connect to the protected database as TARGET and to the downstream Recovery Appliance catalog as CATALOG.

   "Connecting to the Protected Database and Recovery Appliance Using CLI"

3. Allocate an RMAN SBT channel that corresponds to the downstream Recovery Appliance, place the protected database in MOUNT mode, and restore the protected database.

   All these statements must be enclosed within a RUN block as shown in "Example: Restoring and Recovering an Entire Database With the Existing Current Control File".
