Chapter 4. Configuring Oracle GoldenGate

Having installed Oracle GoldenGate 12c, it must be configured in order to meet all of your data replication, data migration, or upgrade requirements. After initially discussing the main GoldenGate parameters, this chapter will provide a methodical approach to the configuration process, stepping through each task to give the depth of information necessary to successfully implement GoldenGate on Oracle 11g and 12c environments. You will learn the basic steps necessary to configure one-way replication in a GoldenGate environment, including data synchronization between the source and target.

This includes the following discussion topics:

  • Choosing the most appropriate instantiation method to synchronize the source database with the target prior to replication
  • Preparing and configuring the data capture for the initial load on the source system
  • Configuring change synchronization on the source system
  • Configuring change synchronization on the target...
