1. Install Delphix Software on x86 VM
x86 hardware
Allocate
Storage
Any type
Installs on any x86 hardware as a Vmware VM, and is shipped as OVA file
Supports any major Oracle O/S such as Linux, AIX, HPUX, Solaris, OpenSolaris
Uses any storage
2. One time copy of source database
Database
Production
Instance
File system
RMAN APIs
After installation of Delphix, then the source database host is registered with Delphix.
Delphix will auto discover any databases on the source host.
A user then can pick a source database, and Delphix makes a one time only initial copy
using RMAN APIs.
4. Incremental forever change collection
Database
Production
Instance
File system
Changes are collected
automatically forever
Data older than retention
widow freed
Delphix will continue to pull in the changes, and only the changes incrementally and forever,
holding on to 2 weeks of changes and purging changes older that 2 weeks. The 2 week window
is called the timeflow. A virtual database can be provisioned from anywhere in the timeflow
down to the transcation SCN. The two weeks is configurable and is often be extended longer.

Fiber Channel
One compressed copy of production along with 2 weeks of changes
stored on the virtualization appliance and all clone copies share the
duplicate datablocks
7. I/O Virtualization
3 physical clones 1 source 3 virtual clones of 1 source
Virtualization layer takes one source
copy, compresses it, pulls in ongoing
change to the source and orchestrates
I/O access between clone database
and storage
Space wastage and creation time delays
8. Timeflow: Production change capture
Clones created in minutes
Developer VDB
QA VDB
Production
Development, QA
Can spin up a copy of production for use in development in minutes with
almost no storage overhead. The development database along with all
changes made to it can be forked off to be used by QA in minutes
