This book focuses on using GoldenGate Services (GGS) in combination with the microservices architecture in Oracle cloud (OCI), primarily for migrating and integrating data from various sources and targets.
The book begins with a practical example of using GGS on a Marketplace virtual machine, gradually moving on to a detailed discussion of implementing GoldenGate as a service in OCI. The book provides illustrative guides to data replication between DBMSs (such as Oracle, Postgres, and big data objects such as Kafka). It also covers monitoring techniques using Enterprise Manager and Grafana dashboards. A comparative analysis of traditional virtual machine-based GoldenGate installations and the OCI service model is presented. Particular attention is paid to zero downtime migration (ZDM) and the use of GGS to migrate databases from on-premises to OCI. Some chapters discuss cross-cloud replication using OCI GGS and provide real-life examples.
By the end of this book, you will have a comprehensive understanding of the architectural design of GoldenGate services and learn how to replicate data using GGS, allowing you to replicate customizations in your own environments.
What you will learn
Configure GoldenGate services for high availability (HA), disaster recovery (DR), data migration to the cloud and data migration to a data lake or lakehouse
Perform logical data migration to the cloud using the ZDM tool (ZDM uses GoldenGate internally).
Replicate data for high-volume data processing purposes
Control GGS using Enterprise Manager and Grafana
Replicate data in a multi-cloud environment
Who should use this book
Oracle DBAs who want to replicate data or use Oracle GoldenGate services for migrating and configuring high availability (HA) and disaster recovery (DR), as well as data engineers who want to create a data warehouse, data lake, data lakehouse for transferring data in near real time.
