A step-by-step guide to practising Oracle GoldenGate High Availability (HA) options, Microservices, and Real-Time downstream techniques Key FeaturesUnderstand how and when they're used classic Vs. MicroservicesLearn how to use real-time downstream methods based on the environmentLearn how to solve Oracle GoldenGate (OGG) Conflict Detection and Resolution (CDR) in bi-directional, active replication Learn how to implement high availability for mission-critical systems using Oracle GoldenGate XAG components Learn how to set up bi-directional replication between pluggable databases (PDBs) in a multi-tenant environmentLearn how to use differently typed of replicates in pluggable databases (PDBs) in a multi-tenant environment DescriptionThe book starts with a brief introduction about Oracle GoldenGate with Microservices and how to configure high availability using various methods. Oracle GoldenGate Microservices Architecture (MA) is a similar architecture based on REST APIs which enable us to configure, monitor, and manage Oracle GoldenGate services using a web-based user interface. Each module supports a specific business goal and uses a simple, lightweight, and well-defined interface to communicate with other sets of services. What will you learnBy the end of the book, you will come across a few case studies about how to use Microservices, Kubernetes, REST APIs in Oracle GoldenGate, and How to monitor Oracle GoldenGate processes in real-time environments. This book also helps how to use various file systems like ACFS, DBFS, and NFS in high availability for Oracle GoldenGate.Who this book is forThis book is intended for anyone looking for how to set up and configure Uni-directional, Bi-directional replication in mission-critical environments either using classic Oracle GoldenGate OR Oracle GoldenGate with Microservices. This book also helps various methods to implement real-time downstream techniques.Table of Contents1. Introduction to Oracle GoldenGate HA - XAG Components2.
