There are several prerequisites for setting up ASE warm standby databases.
The Replication Server that manages the active and standby databases must be installed and running. A single Replication Server manages both the active and the standby database.
The Adaptive Servers that contain the active and standby databases must be installed and running. Ideally, these databases should be managed by data servers running on different machines.
Before you can add a database to the replication system as an active or standby database, it must already exist in the Adaptive Server.
