Oracle Maximum Availability Architecture (MAA) GoldenGate Hub

To achieve the highest levels of availability, resulting in zero or near-zero downtime for both unplanned outages and planned maintenance activities, customers frequently use the combination of Oracle Real Application Clusters (Oracle RAC), Oracle Active Data Guard, and Oracle GoldenGate. Traditionally, Oracle GoldenGate is installed and run locally on the database server that the GoldenGate processes connect to. When used with Oracle Grid Infrastructure Standalone Agent (XAG), Oracle GoldenGate processes can be configured to seamlessly relocate or fail over between Oracle RAC nodes and follow Oracle Active Data Guard switchover and failovers.
