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.
