About Course
Real Application Clusters is an acronym for them. It is an Oracle DB high-availability solution. Here, utilizing shared discs, two or more nodes are clustered to form a single database. Therefore, the DB side has no single point of failure. A cluster is made up of several connected computers or servers that, to clients and programs, appear to be a single server. You can cluster Oracle databases thanks to Oracle RAC. Enroll today to earn your certification.
