Upgrade with Zero Downtime

Upgrade with Zero Downtime

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.
  • IBM DB2. For more information, see the
    Informatica MDM Multidomain Edition for IBM DB2 Version 10.1 Zero Downtime Installation Guide
    .
  • Oracle. For more information, see the
