The Future & Migration Path

With the Classic Architecture now desupported, the migration to Microservices is a strategic necessity. This section outlines key considerations and the expanded use cases enabled by the modern architecture.

Migration & Strategic Recommendations

  • ✓ New Deployments: Exclusively utilize the Microservices Architecture to ensure access to the latest features, security, and long-term supportability.
  • ✓ Migration for Classic Users: Initiate migration planning to MA without delay due to the desupport of Classic Architecture in version 23ai.
  • ✓ Thorough Testing: Invest in comprehensive testing of migrated configurations and team training, performing dry runs of the migration utility.
  • ✓ Leverage MA's Capabilities: Explore advanced features like REST APIs for automation and the Performance Metrics Server for enhanced monitoring to improve operational efficiency.

Modern Use Cases for Microservices Architecture

  • ✓ High Availability: Implement robust HA and disaster recovery solutions, including active-active configurations across data centers.
  • ✓ Data Mesh Architectures: Enable data sharing and consistency between microservices using GoldenGate as a data product creator.
  • ✓ Event-Driven Architectures: Publish database change events to event brokers like Apache Kafka for real-time downstream processing.
  • ✓ Real-time Analytics & AI: Provide timely data feeds for GenAI applications and analytics platforms that require up-to-the-second information.
  • ✓ Data Lake/Warehouse Ingestion: Continuously ingest real-time data from operational systems into analytical platforms.

Automating DBA Tasks with Oracle GoldenGate - Part 2

Automating DBA Tasks with Oracle GoldenGate In this post, we will explore how to automate DBA jobs with Goldengate. If you're reading this directly, I recommend checking out Part 1 first to understand how it works. If you've already read Part 1, feel free to continue from here! Or you are already familiar with goldengate you are good enough to continue. Steps to Automate User Management in Goldengate Configure Goldengate parameters and place the required shell and SQL scripts. Add the necessary input into GG_USERMGMT_TB, such as the username, database name, and granted roles. Verify that the user has been successfully created in the database. This setup is sufficient to bring your bright idea to life using your environment. Here, the E_E01_1 extract acts as the master process to automate DBA job user management operations. I have two databases, orclpdb01 and orclpdb02, with the master extract process configured and running on or...
