Introduction to Oracle 1Z0-068 : Oracle Database 12c: RAC and Grid Infrastructure Administrator Exam

Oracle Database 12c: RAC and Grid Infrastructure Administration Exam assesses 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 abilities of installing, managing, tracking, tuning and restoring RAC databases, clustering and Oracle Automatic Storage Management (ASM). They should have good understanding of the architectures of the ASM, Clusterware and Oracle RAC databases. They should also know how to install, setup, backup and recoverym 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 clustering.

The Oracle Grid Infrastructure for an independent server is the Oracle software that offers system support for database including 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 infrstructure before installing Oracel Database.
