What is the difference between Oracle clusterware and Real Application Clusters? If we have 2 servers and want to join them into a cluster why there are two separate software products?

Oracle Clusterware is the clustering software that is a component of an Oracle RAC setup. Rather than being seen as a separate software product, Clusterware is part of the software stack (which includes the OS, ASM, Oracle RDBMS) that makes up an Oracle RAC cluster/deployment. Oracle support other clustering products in a RAC environment on some operating systems.

You could (in theory at least) also use the clusterware tools independently from RAC, to "cluster" apps other than Oracle RDBMS. I don't think that's widely used though. –  Mat Feb 14 '13 at 8:50
