  Hi

  Oracle RAC allows multiple computers to run the Oracle RDBMS software simultaneously while accessing a single database, thus providing a clustered database.

  In a non-RAC Oracle database, a single instance accesses a single database. Where the "database" consists of a collection of data files, control files, and redo logs located on disk; the "instance" comprises the collection of Oracle-related memory and operating system processes that run on a computer system.

  In an Oracle RAC environment, two or more computers (each with an instance) concurrently access a single database. This allows an application or user to connect to either computer and have access to a single coordinated set of data.
