Описание курса:
This Oracle GoldenGate 12c training covers installing and configuring advanced features of the product, including active-active replication and conflict detection/resolution. Explore in more depth topics introduced in the fundamentals course, such as Event Marker and Advanced Data Transformation techniques. Implement 3-way, Multi-Master configurations and experiment with Oracle RAC, integrating Oracle GoldenGate with Oracle clusters. Configure Oracle GoldenGate replication in a Multi-tenant database supporting pluggable databases (PDBs.)
Enrolling in this Oracle GoldenGate 12c training will help you develop your installation and configuration skills. By interacting with top Oracle instructors, you'll be able to ask questions as you learn to solidify your understanding.
Integrate your organization's disparate data across heterogeneous databases for improved decision-making. Become more efficient at configuring and implementing the more advanced features of Oracle GoldenGate used together with the Oracle RDBMS 12c. Enable Zero-Downtime Migration: this course also allows you to simulate a system upgrade. You'll develop the skills needed to survive an aborted migration, incurring zero data loss. Hone these skills by engaging in hands-on demonstrations and exercises. You'll also build two-way and three-way active-active replication configurations. Explore both basic and advanced conflict detection and resolution (CDR). Review basic product-provided CDR, with more advanced custom CDR techniques implemented using SQLEXEC and stored procedures.
