Course Description

Prepare to pass exam: Oracle Database 19c: RAC, ASM, and Grid Infrastructure Administration

The Oracle Certified Expert, Oracle Database 19c: RAC, ASM, and Grid Infrastructure Administrator certification is for Database production Systems Administrators and Database Administrators with 12-18 months of experience utilizing RAC, ASM, and Grid Infrastructure. Your worth to your business and the market is increased by passing this exam, which assesses your knowledge and abilities in installation, setup, backup and recovery, monitoring, and tuning of these components.

The Oracle Database 19c: RAC, ASM, and Grid Infrastructure Administration exam requires in-depth knowledge of Oracle’s Real Application Clusters (RAC), Automatic Storage Management (ASM), and Grid Infrastructure technologies. To prepare effectively, it is essential to focus on key areas like RAC architecture, ASM, and Clusterware, while also gaining practical hands-on experience through setting up a practice lab.
