Introduction to Oracle 1z0-082: Oracle Database Adminstration 1 Exam

Oracle Database 12c: RAC and Grid Infrastructure Administration Exam assess the abilities of the Database Administrators and System Administrators who have at least 1 year of experience in RAC and Grid Infrastructure. The candidates should have the ability to install, manage, tracking, tuning and restoring RAC databases, cluster, and Oracle Automatic Storage Management (ASM). They should have a good understanding of the architectures of the ASM, Clusterware, and Oracle RAC databases. They should also know how to install, setup, backup, and recovery monitoring and tuning of these components.

Oracle Real Application Clusters (RAC) in database computing is a choice for Oracle Database software developed by Oracle Corporation, it provides clustering software and high availability in Oracle database environments. With the Enterprise Version, Oracle Corporation includes RAC, provided the nodes are clustered using Oracle Clusterware. Oracle RAC allows several machines when accessing a single database, to run Oracle RDBMS software simultaneously, offering to cluster.

The Oracle Grid Infrastructure for an independent server is the Oracle software that offers system support for a database including the file system, volume management, and automation of the restart process. If you want to utilize the Oracle restart or Oracle Automatic Storage Management (ASM) services, you have to install Oracle grid infrastructure before installing Oracle Database.


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.
