When you need to upgrade Informatica MDM software but stakeholders require uninterrupted access to master data in the MDM Hub Store, you can use the zero downtime feature. While the primary Hub Store is offline for software updates, a secondary duplicate Hub Store stores changed data and responds to requests for master data.
Informatica MDM uses Oracle GoldenGate for database replication.
Zero downtime is supported for Hub Stores that reside within IBM DB2 databases or within Oracle databases.
