Oracle 11g Real Application Clusters (RAC) for Administrators


Course code: 
Time Unit: 

This hands-on course teaches students all aspects of Oracle® 11g RAC administration. Students will begin with a solid foundation in Oracle Clusterware and RAC architecture. Students will then 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.
