Mr. Howard J Roger at his web size DIZWELL INFORMATICS has written an excellent articel on 'Building a 10gR2 Laptop RAC on Windows'' in which he greately explained about installation and maintenance of RAC on a PC. Following link will take you the article.
If you feel installing Oracle RAC, VMWARE and other stuff would be little bit hectice, at least, for the biginner, then, don't worry, Oracle has a ready made solution for you.
Desktop Data Centers: Oracle-on-Linux VMware Tool Kits
Oracle, VMware, Red Hat and Novell have teamed up to provide everything you need to run a full Oracle Database 10g on Linux environment on your Windows desktop—including the operational infrastructure and step-by-step instructions on how to use Oracle Database 10g and Oracle Real Application Clusters.
Note: These kits are for evaluation and development purposes only. Oracle will not support any deployments of these packages.
Currently the test cases are available on RED HAT and NOVELL only.
Good books (in my view) are:
