Basically, what I am complaining about is the tendency to push RAC to everybody. What people don't understand is that adding machines also adds a layer of complexity. I have a lot of experience with Oracle and I needed a lot of help from Gopal when I did my first Oracle 10G/ASM installation. I am very grateful for his help and his book has been of immense help, but RAC is a very complex product. Essentially, RAC makes a good DBA a must. Very few small companies are willing to hire a full time DBA just to manage a database. In addition to that, I once worked for a company that went from Oracle to Postgres, just because they felt that Oracle is too big, too complex and too expensive for them. Wang Trading was a small hedge fund in Norwalk, CT that got rid of both Oracle and me. That sort of things tends to catch my attention. Now, they're out of business, I have no idea why.
