A step-by-step guide for designing, implementing, and managing Oracle GoldenGate with HUB Architecture. Oracle GoldenGate is a software product that allows you to replicate data from one database to another. If you are interested in using Oracle GoldenGate Microservices (OGG MA) in HUB configuration for database upgrade, migration, and data replication, then this book is a valuable resource for you. This book provides step by step instructions, explanation about the whole architecture design for Oracle GoldenGate Microservices in HUB configuration including HA (High Availability) and DR (Disaster Recovery). This new technology is explained in the real project’s examples for the database upgrademigration, data replication using OGG MA in HUB configuration, using REST API, command line solutions or web interface. Everything is explained from the beginning of the architecture design until full installation and administration. Book contains also real example of the code, how to handle different activities via REST API. Via Cloud Control will be installed OGG plugin to monitor all components. Architecture designed is proven at the end of the book, where is explained via exampleexecution that solution works as designed in the DR and HA situation.
