Selective data distribution recreates objects on the target system in a replica that preserves the object relationships and naming on the target server without interfering with active objects on the system. Objects within a replica are read-only and disabled. They cannot be failed over. However, you can use virtual databases (VDBs) within a replica as the source for provisioning new VDBs.
Replicas
A replica contains a set of replicated objects. These objects are read-only and disabled while replication is ongoing. To view replicated objects in DCT, navigate to Data > Policies > Replication and select the SDD policy to see its source objects and execution history. You can also view replica details via Replica insights.
Multiple replicas can exist on the system at the same time. Active objects can exist in the system alongside replicas without interfering with replication updates. VDBs within a replica can also be used as a source when provisioning. For more information, read Provisioning from Replicated Data Sources or VDBs.
Failover
Selective data distribution does not support the failover of replicas.
