That book is tremendous if you want to understand the various algorithms for things such as redo/undo, cache management, etc but I don't think it is all that useful for purely sql tuning. I don't think there is a single source that will give you the background you are looking for. I've learned something new from every source I've read. Nothing can really replace experience in working out actual sql problems though. -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Martin Klier Sent: Monday, June 07, 2010 9:30 AM To: cicciuxdba@xxxxxxxxx Cc: oracle-l-freelists Subject: Re: books on query tuning I think the new Performance Firefighting book written by Craig Shallahamer should be quite good. Did not buy it for myself yet, don't even know if it's already out. But I like his writing, so I will buy it, it's the next on my list.
