Optional supplemental mentoring

Key Features

* Expert techniques for monitoring and tuning cluster bottlenecks.

* See how to optimize your cluster architecture for optimal performance.

* Learn secrets for monitoring transient RAC performance issues.

* See how to minimize pinging and optimizer the cache fusion interconnect.

* Understand expert tips for managing disk I/O in RAC.

* See how to expose the internal concurrency, resource coordination and locking mechanism within RAC.

* See how to tune RAC block transfers with the cache transfer views.

* Learn how to monitor RAC performance with Oracle Grid control.

* Get real-world scripts for proactive RAC and Grid performance management and exception reporting.


This is an intensive 3-day Oracle Real Application Clusters (RAC) tuning course.

Unlike other Oracle RAC tuning classes, this course is taught by a practicing RAC expert with years of experience in tuning mission-critical RAC databases. 

The course focuses on RAC disk I/O tuning, SGA tuning and tuning the cache fusion cluster interconnect.  The course will also include specialized Oracle RAC tuning script for monitoring all of the critical RAC performance areas.

This Oracle RAC training is special because this course is taught by a veteran Oracle Certified DBA with years of full-time experience.
