Who Should Enroll? (Target Audience)

This course is tailored for three specific groups:

Prerequisites: Basic SQL knowledge and a general understanding of databases (any vendor). No prior GoldenGate experience is required.

4. Troubleshooting & Logging

Let's face it—OGG breaks. When an Extract abends at 2:00 AM, you need to fix it fast. The course includes a dedicated section on reading ggserr.log, using SEND EXTRACT commands, and resolving the dreaded "Lag" issues.

Section 10: BONUS – GoldenGate 21c/23c New Features & Exam Prep (Length: 3 lectures / 30 min)

10.1 What’s New in 21c/23c vs 19c
10.2 Tips for Oracle GoldenGate 19c Certification (1Z0-447)
10.3 Final Exam (30 Multiple-choice questions + 3 Hands-on lab tasks)

Key Capabilities of GoldenGate 19c:

High Availability: Zero-downtime migrations and upgrades.
Bidirectional Replication: Active-Active databases for load balancing.
Heterogeneous Support: Move data between Oracle, SQL Server, PostgreSQL, MySQL, and even big data platforms like Kafka.
Cloud-Ready: Seamless replication to OCI (Oracle Cloud Infrastructure), AWS, or Azure.

The Skill Gap: Despite its power, GoldenGate has a reputation for being "complex." The 19c version introduced microservices architecture (Web UI, REST APIs), which has changed the deployment landscape. Most online tutorials are outdated, covering the legacy classic architecture. This is precisely why the Udemy - Oracle GoldenGate 19c Learn and Master course is a game-changer.
