The following image shows an example of a source system and a target system:

The installed versions of

Multidomain MDM

and the database software must be the same on the source system and the target system. The MDM Hub Master Database name must be the same on both systems. The Operational Reference Store schema or user name can be different, but the structure of the schemas must be identical.

You can install Oracle GoldenGate on the source system or target system hosts. However, it is recommended to install Oracle GoldenGate on a separate host.

The name of the MDM Hub Master Database can be different. The Operational Reference Store schema or user name can be different, but the structure of the schemas and primary key values of the MDM metadata table

C_REPOS_SYSTEM

must be identical.

Oracle GoldenGate replicates the tables in Operational Reference Store, from the source system to the target system.
