Oracle GoldenGate 12.3 Microservices Architecture just came out. This is a separate build, and in contrary to previous architecture (called now Classic Architecture) has distinct installation binaries and completely different directory structure after installation. Processes are run from different binaries and the whole configuration is also completely different. This article is a complete tutorial which shows how to install and configure OGG 12.3 Microservices Architecture (MA) to replicate a table from Oracle 12.2 to Oracle 11.2.
