Multiple Replication Paths for Warm Standby Environments
You can improve replication performance in warm standby environments with alternate connections and alternate logical connections, or by building end-to-end replication paths.
Creating Multiple Replication Paths for Warm Standby Environments
Use logical connections to bind a replicate connection for a standby database and a primary connection for an active database to create two complete replication paths between an active database and a standby database in a warm standby environment.
Switching Active and Standby Databases
You must switch all the replication paths in a warm standby environment with multiple replication paths when you switch from the active to the standby database.
