Introducing OpenEdge Replication : OpenEdge Replication terminology : Source and target databases : The target database
 
The target database
The target database is an identical copy of the source database. You can set up either one target database or two target databases (for additional redundancy). The source and target databases should reside on separate machines so the target can run if the source machine fails.
The target database:
*Originates from the source database and contains the same data, schema, logical structure, and some of the same startup arguments as the source database.
*Is updated solely by the source database.
*Does not allow database updates by anything other than the OpenEdge Replication agent.
*Permits queries and reports by users, as well as any non-database write activity (database utilities, for example) if OpenEdge Replication Plus is installed. For information on what your OpenEdge Replication installation supports, see Accessing a running replication-enabled database. See Utilitiesand OpenEdge Replication for supported non-database write activity.
You can back up an online or an offline target database. For details, see Backing up an online target database.
The figure below shows the source and target databases in the OpenEdge Replication model.
