Oracle Database 10g: Data Guard Administration Release 2

Trainingsziel

Dieser Kurs vermittelt folgende Kenntnisse und Fähigkeiten:

Steigerung der Verfügbarkeit und Reduzierung des Risikos durch das Erlernen der Anwendung von Oracle Data Guard. In diesem Kurs erlernen Sie wie sie ihre Oracle DB gegen geplannte und ungeplannte Ausfälle schützen können. Es werden weiterhin die Data Guard Architektur sowie die Erstellung von physikalischen und logischen Standby Datenbanken besprochen.

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.
