A Replication Server supporting a high availability, warm standby environment has these restrictions:
The replicate server cannot be a replicate Replication Server. No other Replication Server can replicate data into the warm standby Replication Server.
The replicate server can be a primary Replication Server. Data can be replicated out of a primary Replication Server to a replicate database.
See “Managing Warm Standby Applications” in the Replication Server Administration Guide, Volume 2.
