Udemy - Oracle Goldengate 19c Learn And Master ... [better] ✨ 🆒

Most GoldenGate courses on Udemy follow a similar structure, and this one is no exception. It wisely avoids the newer, confusing "Microservices" architecture initially, grounding the student in the "Classic" architecture first.

| Module | Topics Covered | |--------|----------------| | | What is GoldenGate? Use cases (HA, reporting offloading, data integration). Comparison with dblink, Materialized Views, Streams. | | 2. Architecture Deep Dive | Extract (Classic & Integrated), Replicat (Classic & Coordinated), Trail files, Checkpoint table, Manager process. | | 3. Installation & Configuration | Software installation, environment variables (ORACLE_HOME, PATH), Creating subdirs, GLOBALS parameter file. | | 4. Unidirectional Replication | Configuring Extract (primary), Pump (optional), Replicat (target). ADD TRANDATA, ADD EXTRACT, ADD REPLICAT commands. | | 5. Bidirectional / Active-Active | Configuring both sides, handling loops (DBOPTIONS, IGNOREAPPLOPS), conflict resolution methods. | | 6. Advanced Replication | Table-level & schema-level replication, column mapping, transformation (SQLEXEC, COLMATCH). | | 7. Initial Load Methods | Using INITLOAD, direct load, or transportable tablespaces. | | 8. Monitoring & Troubleshooting | GGSCI commands (INFO, STATS, SEND), viewing report files, logdump utility, handling abended processes. | | 9. Performance Tuning | Parallel Extract/Replicat, GROUPTRANSOPS, FETCHOPTIONS, tuning trail file size. | | 10. Integration with Cloud | Replication to/from Oracle Cloud (OCI) Autonomous Database, Marketplace images. |

In today's data-driven economy, businesses cannot afford data downtime or latency. Whether you are migrating critical databases to the cloud, setting up high-availability systems, or feeding real-time data into analytics engines, data synchronization is vital. Most GoldenGate courses on Udemy follow a similar

GoldenGate 19c offers tighter integration and improved performance with the Oracle Database. When running Integrated Extract in Oracle Database 19c, capture efficiency has been substantially improved over previous releases, enhancing throughput while reducing overall processing resources for the same workload. The platform introduces Parallel Replicat, a new feature that significantly improves apply performance by applying changes in parallel across multiple threads, ideal for high-volume environments.
