Oracle GoldenGate 12c: Fundamentals for Oracle

Prix: 2 680 €Durée: 4 joursCode de Réference: D84357 Catalogue

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.

Learn To:

  • Explain Oracle GoldenGate advanced configuration options.
  • Describe and take advantage of the Integrated Capture feature and the recently introduced Integrated Replicat feature
  • to replicate complex data types and compressed data.
  • Integrate the Database File System (DBFS) with Oracle GoldenGate to achieve Maximum Availability.
  • Configure and implement the Oracle GoldenGate Event Marker system.
  • Enable data transformation based on event records in the transaction logs or in the trail files.
  • Perform zero-downtime database migration.
  • Set up and manage advanced deployment models, like 3-node multi master replication configuration.
  • Master Oracle GoldenGate facilities to detect and resolve data conflicts in active-to-active replication implementations.
  • Use a simulated Oracle RAC configuration to experiment with the Oracle GoldenGate Clusterware-aware facilities,
  • which ensure seamless data replication in case of node failure.

Benefits to You

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

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.

Active-Active Replication and CDR

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.

Configure Integrated Extract Groups

Configure Integrated Extract Groups and Integrated Replicat groups: the Integrated Extract feature and the recently
introduced Integrated Replicat feature are also covered in depth. You'll learn to configure integrated extract groups
operating in both local and downstream deployment modes and to configure Integrated Replicat groups, which enable
automatic, dependency-aware parallel apply streams for dramatically improved data delivery performance.

Learn to Utilize Advanced Features

Upon completing this course, you'll be able to utilize the more advanced features of Oracle GoldenGate 12c, including:
integrated capture, integrated delivery, active-active replication, conflict detection and resolution, DDL/DML replication,
Oracle GoldenGate event marker subsystem, advanced data manipulation and transformation techniques and advanced
data mapping. In addition, you will use a simulated Oracle RAC configuration to experiment with the Oracle GoldenGate
Clusterware-aware facilities, which ensure seamless data replication in case of node failure.
