Oracle GoldenGate 12c is a highly configurable product. Obtaining the optimal configuration for your application may be a challenge, but you will be rewarded with a robust, scalable, secure, and high performance data replication and synchronization solution. What's more, the additional options and utilities help you to build on the existing configuration when the system requirements change with time.

In this chapter, we discovered various powerful configuration options provided by the Event Marker Interface that enable event-based processing and huge performance gains in data replication.

In the next chapter, Chapter 6, Configuring GoldenGate for HA, we will discuss high availability options and how Oracle GoldenGate can be RAC aware, providing the ability to failover to a surviving node in a clustered environment.
