Introduction

The ‘Oracle Certified Expert’, ‘Oracle Database 12c: RAC(Reаl Applicаtion Clusters)’ and ‘Grid Infrastructure Administrator’ certification is for Database production Systems Administrators and Database Administrators with 12-18 months of RAC(Reаl Applicаtion Clusters) and Grid Infrastructure experience. It's also a good idea to be familiar with high-availability ideas like clustering. 

After earning this certification you'll be able to set up, maintain, monitor, tune, and recover RAC databases, Clusterware, and ASM(Automаtic Storаge Mаnаgement) environments. You'll also learn how to install, configure, backup, and restore these components, as well as monitor and tune them. You'll also show that you may provide the best configuration for a given set of criteria. This certification boosts your value to your company and in the marketplace as an add-on to the Oracle Database 12c Administrator Certified Professional credential.

Skills You Need 

Database production Systems Administrators and DBAs(Dаtаbаse Administrаtors) who have proved the skills to set up, maintain, monitor, tune, and recover RAC databases, Clusterware, and ASM environments are ‘Oracle Certified Expert’, ‘Oracle Database 12c: RAC’ and ‘Grid Infrastructure Administrators’. They are well-versed in the architectures of Clusterware, ASM, and Oracle RAC Databases, as well as their installation, configuration, backup and recovery, monitoring, and tuning.

ACFS(Automatic Storage Management Cluster File System)

Oracle Automatic Storage Management Cluster File System (Oracle ACFS) is a multi-platform, scalable file system and storage management solution that extends the capability of Oracle Automatic Storage Management (Oracle ASM) to accommodate client data stored outside of the Oracle Database.

ASM(Automatic Storage Management)

From version Oracle 10g forward, Oracle Corporation has included Automatic Storage Management as a feature in the Oracle Database. ASM seeks to make database datafiles, control files, and log files easier to manage.

ASM Cluster File System

Oracle ACFS (ASM Cluster File System) is a POSIX and X/OPEN compliant cluster file system that supports a wide range of operating systems and server architectures, including Oracle Engineered Systems like the Oracle Exadata Database Machine and Oracle Database Appliance.

Cluster Database

A cluster is a schema object that holds information from one or more tables that share one or more columns. All rows from all tables with the same cluster key are stored together in Oracle Database.

Grid Installation

You must first install the Oracle Grid Infrastructure for a cluster software, which includes Oracle Clusterware and Oracle Automatic Storage Management, before installing Oracle Real Application Clusters (Oracle RAC) and Oracle RAC One Node using Oracle Universal Installer (OUI) (Oracle ASM).

Oracle Grid Infrastructure

Oracle software that offers system support for an Oracle database, including volume management, file system, and automated restart capabilities, is known as Oracle Grid Infrastructure for a standalone server. Oracle Grid Infrastructure must be installed before your database if you want to use Oracle Restart or Oracle Automatic Storage Management (Oracle ASM). Oracle Grid Infrastructure is a program that includes Oracle Restart and Oracle ASM for a solitary server.

Real Application Cluster

Customers can use Oracle Real Application Clusters (RAC) to run a single Oracle Database across multiple servers to increase availability and horizontal scalability while using shared storage. User sessions connected to Oracle RAC instances can failover and safely replay modifications during outages, obfuscating the impact of failures on end-users.

Resources for Preparation

To aid with your preparation, here are some well-structured resources on Coding Ninjas that are available for free.

Frequently Asked Questions

What steps do I need to take to get Oracle certified?

You must complete all training requirements, pass the required exam(s), and submit the Course Submission Form to become Oracle Certified. On the Oracle Certification Site's Oracle Certification page, you may learn more about becoming Oracle Certified.

What is the purpose of Oracle RAC?

Customers can use Oracle Real Application Clusters (RAC) to run a single Oracle Database across multiple servers to increase availability and horizontal scalability while using shared storage.

What is Oracle 12c's RAC?

Oracle Database allows many instances operating on different servers to access the same physical database stored on shared storage using the Oracle Real Application Clusters (RAC) option. The database spans several hardware systems yet appears to the application as a single unified database.

What is Oracle Real Application Clusters (RAC) grid?

Oracle RAC is built on the foundation of a high-availability cluster. Oracle Clusterware is a portable cluster software that allows the clustering of independent servers to cooperate as a single system.

What is RAC configuration, and how does it work?

Oracle Real Application Cluster (RAC) is a database architecture that allows you to "share everything." It can provide high availability and load balancing. An Oracle RAC cluster typically consists of two or more Oracle RAC nodes clustered together and sharing storage.
