How Oracle GoldenGate Works

Capture: committed transactions are captured (and can be filtered) as they occur by reading the transaction logs.

High Availability for Oracle Database When to Use Active Data Guard vs. GoldenGate

• Disaster Recovery / Data Protection

� Active Data Guard: simple full Oracle Database protection

� High-performance, simple, drop-in solution for HA and DR, readable at standby

� Zero data loss, integrated data corruption protection, switchover / failover

� DR for all data types & apps including packaged apps that can’t be changed

14

• Information Distribution, Flexible HA

�GoldenGate: heterogeneous, active-active, migrations

� Heterogeneous replication, transformations, subsetting, multiple topologies

� All sites fully active (read/write): avoid or manage conflicts at application level

� Enable minimal downtime app migrations with 2nd database copy

Powerful Combination!Integrated HA, DR and Active-Active Replication
