Title of the Course: Oracle Data Guard
Brief Description: This course offers a complete understanding of Oracle Data Guard, Oracle's disaster recovery and high availability solution. It covers architecture, configuration, role transitions (switchover/failover), monitoring, and management of physical and logical standby databases, ensuring data protection and business continuity across primary and standby systems.

Duration: 2–3 weeks
Goal: Set up, monitor, and switch over Oracle Data Guard environments
Target: Oracle 19c/21c with Linux (VirtualBox or OCI)
Goals: Understand what Oracle Data Guard is and how it works, Learn types of standby DBs and protection modes
| Topic | Description |
|---|---|
| What is Data Guard? | Architecture, primary vs standby |
| Physical vs Logical Standby | Core differences, use cases |
| Protection Modes | Maximum Protection, Availability, Performance |
| Log Transport vs Apply | How redo is sent and applied |
| Broker vs Manual Configuration | When to use DGMGRL |
| Licensing & RAC support | Understand requirements for Enterprise Edition |
Goals: Prepare environment for Data Guard (Primary + Standby)
| Task | Details |
|---|---|
| Install Oracle 19c on 2 Linux VMs | Use VirtualBox or Cloud (OCI/AWS) |
| Configure static IP and hostname resolution | /etc/hosts entries |
| Enable FORCE LOGGING on Primary | ALTER DATABASE FORCE LOGGING; |
| Configure ARCHIVELOG Mode | Enable redo archiving |
| Create standby log files | ALTER DATABASE ADD STANDBY LOGFILE |
| Configure tnsnames.ora and listener.ora | Define entries for both DBs |
| Setup passwordless SSH (optional) | For automation scripts |
Goal: Set up and validate Oracle Data Guard (manual & broker)
Manual Configuration Steps:
Optional: Use Data Guard Broker (DGMGRL)
Goals: Monitor & validate Data Guard health
| Task | Tool/View |
|---|---|
| Check Redo Apply Lag | v$dataguard_stats, v$standby_log |
| Validate Sync Status | dgmgrl show configuration |
| Auto Start of Redo Apply | LOG_ARCHIVE_DEST_STATE_n=ENABLE |
| Alert Log Analysis | /u01/app/oracle/diag/.../alert.log |
Practice HA scenarios
| Scenario | Command |
|---|---|
| Planned Switchover | DGMGRL> switchover to standby_db; |
| Unplanned Failover | DGMGRL> failover to standby_db; |
| Reinstate Primary | DGMGRL> reinstate database db_name; |
| Flashback Primary | Enable FLASHBACK ON for rollback after failover |
What will the learner be able to do after this course?
After completing the Oracle DG course, the learner will be able to design and implement a Data Guard setup to ensure automatic failover and disaster recovery in production environments. For example, in a financial application handling real-time transactions, they will be able to configure a Physical Standby Database for the Primary Database. In case of a primary site failure, they can perform a failover to the standby, ensuring zero data loss and continuous application availability without downtime.
