Just finished reading the book by Jonathan Lewis titled “Oracle Core: Essential Internals for DBAs and Developers“. I think I picked it up at the Collaborate 13 conference in Denver last April but haven’t had time (or taken the time) to read it.
Reading a book like Oracle Core can be a challenge because it is pretty dense with example scripts and outputs including dumps in hex. So, I decided to take the strategy of pushing myself to crash through the book without carefully following every example. I may only have absorbed about 10% of the material but if I didn’t jam through it I would have gotten 0%!
I picked up Oracle Core because I had read another book by the same author titled “Cost-Based Oracle Fundamentals” which has paid for itself 100 times over in terms of helping me tune queries. I highly recommend Cost-Based Oracle Fundamentals without reservation. But, like Oracle Core it can be a challenge to just sit down and read it and follow every SQL example and output. Probably it would be worth making a first pass focusing on just the English language text and skimming the examples, maybe delving into the examples of most interest.
In the case of Oracle Core I haven’t yet put it to practical use but I’m glad to have at least skimmed through it. Now I know what’s in it and can refer back to it when needed.
Next I hope to start reading up on Oracle 12c since I plan to get my certification this year. But, I wanted to finish Oracle Core before I moved on, even if I only read it at a high level.
