Oracle 1z0-082: Oracle Database Administration 1 Exam Certification Path

The Oracle Certified Expert, Oracle Database 12c: RAC and Grid Infrastructure Administrator certification is for Database Development Systems Managers and Database Administrators with at least 1 year of RAC and Grid Infrastructure experience. It is also recommended to understand high availability concepts and clustering. To earn this certificate, you should have the ability to install, manage, monitor, and recover RAC databases, Clusterware, and ASM environments. You will get a complete understanding of the architecture of the Clusterware, ASM, and RAC databases while preparing for the exam. After earning this certification, you will gain the skills of installing, setup, backup and recovering, tuning, and monitoring these components. Self-study courses are great sources for the preparation of the Exam, but they do not meet the requirement of the training. To meet the requirement of the training course must be offered by Oracle University Training Center, Oracle Authorized Education Center, Oracle Authorized Partner, or Oracle Workforce Development Program. Courses can be a live virtual class, training on demand, learning subscription, or instructor-led in-class.
