OUD 12C - Sample Configuration Process for OUD Replication Between on Premise and Remote Data Center
(Doc ID 2998372.1)

Applies to:
Oracle Unified Directory - Version 12.2.1.3 and laterInformation in this document applies to any platform.
Goal
There can be many architectures for replication between on premise (short: onprem) and a remote data center.
The use case in this document is a sample and can be a reference for other use cases.
Sample use case:
- First data center named DC1. This will be on-premise where there are 4 OUD servers. Two will be Directory Server (DSprem1, DSprem2), while the other two are Replication Server (RSprem1, RSprem2).
All servers from DC1 (DSprem1, DSprem2, RSprem1, RSprem2 can be in group ID 1)
- The second data center is named DC2. This is remote data center and it also has 4 OUD servers. The same configuration of 2 Directory Server (DScL1, DScL2), and the other two are Replication Server (RScL1, RScL2).
All servers from DC2 (DScL1, DScL2, RScL1, RScL2 can be in group ID 2)
- In this particular setup the request is to configure replication between DC1 (onprem) and DC2 only between RSprem1 and RScl1 nodes.
To reduce traffic between DC1 and DC2:
There will be no replication between other RS server from DC1 to DC2 (apart from RSprem1).
There will be no replication between other RS server from DC2 to DC2 (apart from RScl1).
- Below image show described architecture:
- This is only an example, obvious similar requests can be imagined.
- When creating the OUD instance(s) and replication configuration the baseDN "dc=SUFFIX_DN" is used for this document.
This is just for tests, it needs to be replaced appropriately for the desired setup.
- To avoid changes to an existing OUD deployment, the deployment will need to ensure connectivity between OUD clusters.
This means that every OUD Instance MUST be able to connect to other OUD Instances, which requires SaaS VPN Routes to be setup
to facilitate access. In case when one of DC is Cloud, the Oracle cloud provides different Gateways (NAT, DRG, LPG) to enable the required connectivity.
