Answer» Oracle Real Application (RAC) provides the INTERACTION of executable file with the Oracle database. It allows the running of any PACKAGED or custom built application with the Oracle database that is running on a server POOL. It provides very HIGH level of availability, flexibility and scalability to run the application and store it to the database. It CREATES the database such that if the pool fails then the database is continued to run from the remaining servers and the load can be distributed. It makes it easier for the administrator to maintain many servers at the same time by load-balancing techniques and providing provision to add more and more servers when the load increases.
