Replication

V00D00 is a logical cross-database replication solution, using open-source philosophy. Stay tuned for more information about new supported platforms.

REDO LOG

Of course V00D00 uses REDO mining in order to reverse change vectors to logical DMLs. No Logminer, triggers or other nasty solutions are being used.

Appliance

Install V00D00 as a physical OS or virtual machine in any away you want - if you can setup secure-enough network from source to V00D00 and from V00D00 to target - you’re covered.

Control

Easy control via website. GUI written in APEX is easy to use and friendly. You don’t need to learn a whole new scripting language just to setup a simple replication.

Open Source Philosophy

We don’t hide our knowledge and you only pay for support.
The rest is free.

Cloud Ready

OK, this is by accident - but virtual appliance architecture brings certain flexibility to implementation in mixed cloud and on-premises solutions.

Migrations

In a lot of cases you need online logical replication only for cross-database migration - just to reduce downtime. If this is your case - feel free to use V00D00 without any consequences.
