Replication Manager 15.0 introduces three wizards to add logical connections, active database connections, and standby database connections.
Previously, these steps were only part of the Configure Replication Environment wizard, which lets you build a warm standby environment in one step. With this version of Replication Manager, you can use a separate wizard for each step in the process, which lets you drop and re-create connections as needed.
Add Logical Connection – adds a logical connection whether you are basing this connection on an existing physical connection or not.
Add Active Database – adds an active database connection to an existing logical connection.
Add Standby Database – adds a standby database to an existing logical connection that already has an active database connection.
