Oracle Database 11g Release 2 Data Guard Course Overview
This course introduces the delegate to the main architectural concepts of Data Guard. Delegates will learn how to use
Oracle Data Guard to protect Oracle Databases against planned and unplanned downtime. They will learn how to create and manage
physical, logical and snapshot standby databases. They will also learn how to use standby databases in a standby role for
reporting, querying and testing purposes.
The
Oracle Database 11g Release 2 Data Guard course is also suitable for users of Oracle Database 10gR2 Data Guard and Oracle Database 11gR1 Data Guard.
Skills Gained
The delegate will practise:
- Preparing a Primary Database for a Data Guard Configuration
- Creating a Physical Standby Database
- Creating a Logical Standby Database
- Creating a Snapshot Standby Database
- Monitoring a Standby Database Configuration
- Managing a Data Guard Configuration
- Troubleshooting Standby Database Configurations
- Tuning a Standby Database
- Backing up and Recovering a Data Guard Configuration
- Using Flashback in a Data Guard Configuration
- Using the Data Guard Broker
Who will the Course Benefit?
The
Oracle Database 11g Release 2 Data Guard course is designed for database administrators and technical support staff who are required
to plan and implement Oracle Data Guard configurations.
Course Objectives
The
Oracle Database 11g Release 2 Data Guard course aims to provide the skills needed to plan, implement, manage and troubleshoot
Oracle Data Guard standby database configurations.
Requirements
A working knowledge of Oracle Database Administration is required. This can be obtained by attendance on the pre-requisite
courses. This course is run in a Linux environment and a working knowledge of the UNIX operating system is therefore highly recommended.
