Virtual Data Pipeline Technology
The Virtual Data Pipeline is a distributed object file system, virtualizing
the core primitives of data management: copy, store, move and restore.
This technology allows the instant creation of virtual copies of point-in-
time data from the collection of unique blocks of data. A single solution
can now be deployed to replace one or more tools, including backup

tools and be used as a platform for search, compliance and analytics tools.
Thanks to VDP, Actifio PAS efficiently captures a copy of changed data
from the database and reuses the data for multiple applications, allowing
the applications to directly access data from Actifio PAS without any
data movement.
The following sections describe the two different configurations for using
Actifio PAS in an Oracle Database environment – Network Configuration
and In-Band Configuration.
Network Configuration
In the Network Configuration in Figure 5, Actifio PAS is connected
through the IP network, with RMAN directly writing to copy data
