- We assume the audience have the basic knowledge of the Oracle Database Administration fundamentals. We do not expect you to be an expert DBA, basics are fair enough.
Learn all about administering Oracle Data Guard. You will gain hands-on experience on performing all the fundamental administration tasks a DBA may need to manage a Data Guard environment.
The course is built-up of lectures that describe the concepts of a subject and practice lectures that allow you to practically implement what you have learnt in the concepts lecture. They are all demonstrated by videos and supported with downloadable files, such as scripts and code examples. The practice lectures do not leave you implement the exercises alone, they are all accompanied with demonstration videos.
If your target is learning all about the fundamental Oracle Data Guard administration with concentration on the practical side, then you are in the right place.
- This course is designed for Oracle Database Administrators who would like to use Oracle Data Guard
- Those DBAs who already have experience on Oracle Data Guard, this course is NOT for them.
This lecture introduces the course to you. It covers the following topics:
- About the Instructor
- Course Goal
- Who should and should not take the course
- Course prerequisites knowledge
- Skills you will learn in the course
- Course layout
- Practice environment requirements
- Course curriculum overview
In this practice, you will create an Oracle 12c single-instance database with ASM in a virtual machine. This database will be used in the practices of this course. If you already have your own virtual machine that has Oracle dabase 12c installed in it, you can use it and skip this practice. However, I recommend building up this machine because all the examples in the course were taken from a database with configuration and naming similar to the one built in this practice.
The practice document is attached to the lecture extras.
Note: you do not actually need to watch the video. You can go ahead and perform the steps in the attached installation document straight away. The video is there for reference.
Total practice expected duration: 60 minutes
This lecture introduces Oracle Data Guard. It explains the benefits of Data Guard and its limitations.
By end of this lecture, you should be able to describe and understand the following:
- What Is Oracle Data Guard?
- Data Guard Usages
- Data Guard Limitations
This lectures discusses the fundamental concepts of Oracle Data Guard.
After completing this lecture, you should be able to describe and understand the following topics:
- Oracle Data Guard Process Architecture
- Types of Data Guard Services
- Types of Standby Databases
- Data Guard Protection Modes
This lectures discusses the fundamental concepts of Oracle Data Guard.
By end of this lecture, you should be able to describe and understand the following:
- Role Transitions: Switchover and Failover
- Data Guard Management Tools
- Oracle Data Guard Broker Benefits
- Flashback Database and Data Guard
In this lecture you will learn the procedure you should follow to build a Physical Standby database. By the end of this lecture, you should be able to do the following:
- Understand Oracle Data Guard requirements
- Plan for creating a physical standby database
- Configure LOG_ARCHIVE_DEST_n parameter
- Create a physical standby databas
This practical lecture will take you through a hands-on tutorial that will show you the procedure to create a Physical Standby database.
You do not have to watch the video. You can download the guide document and follow the steps straight away. However, in case you found a stop unclear for you, you can refer to the video to observe how the step could be practically performed.
This lecture guides you on how to create a logical standby database. After completing this lecture, you should be able to do the following:
- Describe the benefits of logical standby database
- Describe the drawbacks of logical standby database
- The logical standby database practical usages
- Understand the unsupported objects and data types
- Perform the procedure to create a logical standby database
This lecture will take you through a tutorial that will show you the hands-on practical procedure to create a Logical Standby database.
Note: as in all the practices in this course, you do not have to watch the video. You can just download the practice document and implement the steps yourself straight away. You can still refer to the video clip to clarify how a step could be practically implemented.
In this lecture you will learn about the Data Guard Broker concepts and how to practically configure it. By the end of the lecture, you should be able to do the following:
- Understand the Broker capabilities, benefits, and limitations
- Describe the Data Guard Broker components
- Understand the Data Guard Broker Configuration Files
- Use the DGMGRL command-line interface
- Understand the Broker Properties
- Perform the procedure to configure the Data Guard Broker
In this lecture you will learn the management considerations for the physical standby database.
For a physical standby database, you will learn how to do following:
- Start or stop redo apply services
- Specify time delay in the redo apply
- Upgrade or downgrade protection mode
- Handle NOLOGGING operations
- Describe how to use physical standby database for recovering from data corruption
In this practice we will upgrade the Protection Mode in our Data Guard configuration twice, first to Maximum Availability and second to Maximum Protection. We will study the how the primary database will respond in each case when the standby database becomes unavailable.
For a logical standby database, in this lecture you will learn how to do the following:
- Start and stop SQL Apply service
- Define the dataset replicated from the primary database
- Protect replicated tables on a logical standby database
- Handle unsupported tables
- Set the size of memory used by the SQL Apply processes
- Use the alert log file and the V$DATAGUARD_STATUS to monitor the Data Guard
- Obtain the archive log gaps, transport lag, apply lag and active apply rate using SQL*Plus and the Broker
- Obtain information about the standby processes
- Obtain statistics about the logical standby database
By the end of this lecture, you should be able to do the following:
- Describe Data Guard Failover
- Failover to a physical standby database using the SQL*Plus
- Failover to a logical standby database using the SQL*Plus
- Failover using the Broker
- Reinstate the primary database after failover using SQL*Plus
- Reinstate the primary database after failover using the Broker
- Describe the advantages and drawbacks of Fast-Start Failover (FSFO)
- Describe the architecture of the Fast-Start Failover
- Configure the Fast-Start Failover
- Define the Fast-Start Failover conditions
- Enable the Fast-Start Failover
- Start the FSFO Observer
- Disable the Fast-Start Failove
In this practice we will implement and test the fast-start failover in a Data Guard configuration.
- Describe the Active Data Guard and its advantages
- Enable Active Data Guard and use real-time query
- Configure Apply Lag Tolerance
- Configure zero lag between the primary and standby databases
- Force redo apply synchronization in a Real-time Query Environment
This lecture describes how to create and then manage a snapshot standby database. The lecture will teach you how to do the following:
- Describe the snapshot standby databases and their benefits
- Convert a physical standby into a snapshot standby database

In this lecture you will learn how to describe the following concepts:
- The meaning of client or application failover.
- The categories of the service failure that you might face in a data center.
- The challenges faced by a client failover
- The options to implement the client failover
- The procedure to implement client failover
In this lecture you should learn how to do the following:
- Describe the general best practices of using RMAN in a Data Guard configuration
- Manage the Data Guard databases in the Recovery Catalog
- Make the Data Guard related configuration in RMAN
- Recover a missing datafile in the primary database from a standby backup
- Refresh a physical standby database with changes made to the primary database
