Can one replicate to or from an Oracle hot standby database? (4302043)

A hot standby database is a second running database that is created from and transactionally consistent with the primary or master database. Data modifications that are made to the master database are made simultaneously to the secondary database. The secondary database is sometimes referred to as a hot standby database because it is available immediately to pick up application processing if the primary database system fails. It can be used to implement a mission-critical and disaster recovery functions. The question arises as to whether the standby database can be a part of replication, either as source or target.
