Hi Atul,

Being an Oracle apps consultant, I decided to start a blog for Oracle apps interview questions, curriculum, FAQs etc. Atlast I have started that too.

I need your comments to improve my blog. I think, you are the best judge.

how much time does it takes to implement RAC

Atul Kumar says July 9, 2007

Hi Anuj,
It depends on individuals and his/her exposure to RAC but I think 5 days should be good enough time.
