The Oracle Guru Were you correct? This week's answer is:
a. RAC

Real Application Cluster (RAC) is a component of the Oracle9i database product that allows a database to be installed across multiple servers.

RAC's shared disk architecture is an unusual approach to database clustering compared to competing database products.
