Re: Oracle Rman Replication

Hello Ryan,

 To the question #3:

  Generally VVR is faster then Oracle replication (both Advanced replication and new stream based).

  Important thing to consider - in case of data corruption VVR would replicate it as well, so be very careful to use VVR for DR systems.
