ORACLE RAC
A cluster comprises multiple interconnected servers that appear as one server to end users and applications. • With Oracle Clusterware, Oracle RAC enables you to cluster an Oracle database. – Oracle Clusterware enables nonclustered and RAC databases to use the Oracle high-availability infrastructure. – Oracle Clusterware enables you to create a clustered pool of storage to be used by any combination of nonclustered and Oracle RAC databases. • Noncluster Oracle databases have a one-to-one relationship between the database and the instance. • Oracle RAC environments have a one-to-many relationship between the database and instances. – An Oracle RAC database can have up to 100 instances
