Oracle Database 10g: Data Guard Administration


What you will learn:

Minimize the downtime associated with any outage and prevent data loss by learning how to use Oracle Data Guard. The course details Data Guard architecture as well as the creation of physical and logical standby databases. In addition, it examines the performance implications of using various Data Guard features and offers some troubleshooting tips. Learn to use Enterprise Manager Grid Control to create and manage your Data Guard configuration. A workshop that gives students the opportunity to apply what they have learned to meet stated business requirements reinforces skills.

This course counts towards the Hands-on course requirement for the Oracle Database 10g Administrator Certification. Only instructor-led inclass or instructor-led online formats of this course will meet the Certification Hands-on Requirement. Self Study CD-Rom and Knowledge Center courses are excellent study and reference tools but DO NOT meet the Hands-on Requirement for certification.
