OVERVIEW

This hands-on course teaches students all aspects of Oracle® 11g RAC administration. Students will learn a solid foundation in Oracle Clusterware and RAC architecture. Students will install and configure both Clusterware and the database software, as well as cover the administration of both pieces of software using command line utilities. Important topics such as failover, flashback, and backup and recovery are all covered in detail. Students will get hands-on experience with Automatic Storage Management. The course ends with troubleshooting and tuning a RAC system.

DURATION:  5 Days

INTENDED AUDIENCE

This course is designed for database administrators new to the RAC environment.

PREREQUISITES

Oracle 11g Database Administration and at least 6 months of administration experience recommended.

FORMAT/MATERIALS

This course includes a combination of lecture, discussion and numerous computer workshops.  Students will receive an extensive course manual covering the topics presented in class, which will be a valuable reference after class.
