Replicat Replicat is the process that delivers data to a target database. One of the new features in Goldengate 12c is the Integrated Replicated or Integrated Apply feature. the main difference between the integrated replicat and the coordinated replicat is that while in case of the integrated replicat, goldengate will add (or remove) additional apply server processes depending on the workload, in case of coordinated replicat it is user defined partitioning of the workload so as to apply high volume transactions Now how we should chnage our golden gate setup so that it continue to work. Introduction. So we should exit the GGSCI prompt and then relogin to it. Available for only the latest Oracle Database platforms (11.2.0.4 or higher). This article describes how to configure Oracle GoldenGate 12c in order to perform a Bi-directional replication between Oracle source and target Container Database 12c. .
