Troubleshooting Oracle Performance

I am always sceptical about 5 stars reviews, but this book really is excellent. It explained a lot of things I observed over the years, and now they actually make sense:)

The first Troubleshooting book by Antognini was good, but this new-and-improved version is fantastic. Hats off to Christian for the sheer effort he has put into this excellent book.

If you want to learn oracle optimization this is your book.
