Although subscriptions are not used in replicating from the active database to the standby database, you can:
Create subscriptions for the data in a logical primary database, or
Create subscriptions to replicate data from other databases into a logical replicate database.
The create subscription and define subscription commands use the logical database and data server names instead of the physical names.
For detailed information about warm standby applications using replication, see Chapter 3, “Managing Warm Standby Applications” in the Replication Server Administration Guide Volume 2.
