Course overview

Learn how to use Oracle Data Guard in a practical work-relevant setting. You’ll acquire the skills needed to set up, manage and fix standby database configurations. Ideal for DBAs who want to gain the competitive edge for career progression.

Protect your Oracle systems with enhanced technical skills

This course guides you through the full Oracle Data Guard process: from getting it set up, right through to recovery. You’ll use real tools in live labs and pick up practical ways to protect and maintain your databases on a daily basis.

Learning objectives

Configure Data Guard environments in multitenant architectures
Perform switchovers and failovers using both SQL and Data Guard Broker
Automate backup and recovery tasks using RMAN scripts
Implement flashback operations to recover from user or system errors
Diagnose and fix issues with redo transport and apply services
Optimise Data Guard performance through tuning and configuration
Enable and manage Fast-Start Failover (FSFO) for automatic recovery.
Build logical standby databases for flexible testing and reporting

What you’ll learn

This course is filled with practical content alongside relevant theory. Led by Oracle experts, you’ll learn how to work with Oracle Data Guard in real scenarios, from setup through to recovery, building confidence as you expand your working knowledge.

Monitoring and troubleshooting

Knowing how to monitor your Data Guard setup is just as important as configuring it. We’ll explore how to keep an eye on system health, check key views and interpret alert logs to catch problems early. We’ll look at how to identify gaps, fix common sync issues, and understand what’s happening throughout the complete setup. You’ll also get practical tips for diagnosing issues before they become more concerning and learn what to do for a successful resolution.

Role transitions

This part of the course shows you how to switch roles between primary and standby databases with ease. You’ll practise both planned switchovers and emergency failovers using SQL and the Data Guard Broker. We’ll show you how to prepare both databases, run the transition smoothly, and reinstate your original primary if needed. You’ll also learn how to preserve active sessions and use features like application continuity to minimise user disruption. It’s essential learning if you’re responsible for high-availability Oracle systems.

Performance tuning

Getting the most out of your standby database setup means fine-tuning how it handles workloads. In this module, we cover practical performance tips for both physical and logical standby environments. You’ll look at settings like ReopenSecs, NetTimeout, and redo compression. We’ll also dive into SQL Apply tuning, applier/preparer process adjustments, and memory configuration for LCR caches. There’s even support for tools like SQL Tuning Advisor and the Diagnostic Pack. By the end, you’ll know how to identify slow spots and make your standby setup faster and more efficient.

FAQs

This focused course gives you the tools to manage Oracle Data Guard confidently, from setup through to recovery. With expert instructors and hands-on live labs, it’s ideal for anyone managing Oracle systems where uptime and continuity really matter.

What is Oracle Data Guard?

Oracle Data Guard is a high-availability feature used to protect your Oracle database from unplanned outages. It creates standby copies of your database that can automatically take over if the primary system fails. It’s widely used in environments where downtime isn’t an option.

Will this course help with real-world Oracle Data Guard tasks?

Yes, the whole course is built around practical tasks you’ll face as a DBA. You’ll learn how to configure standby databases, manage role transitions, monitor your setup, and recover quickly if something goes wrong. It’s all based on real scenarios you’re likely to see on the job.

What is the difference between physical, logical and snapshot standby databases?

A physical standby database is an exact copy of the primary, kept in sync through Redo Apply. A logical standby uses SQL Apply, allowing read-write access for reporting or testing. A snapshot standby is read-write and isolated from the primary, ideal for testing changes. You’ll work with all three in this course.

How does this course help reduce database downtime?

By learning to implement Oracle Data Guard properly, you’ll be able to switch to standby databases during outages, perform role transitions efficiently, and recover quickly from failures – all essential to minimising downtime in production environments
