Solaris(TM) Performance and Tools:
DTrace and MDB Techniques for Solaris 10 and OpenSolaris

"Solaris Internals" and its predecessor "Sun Performance and Tuning" are wonderful books for giving you the knowledge to know whats actually happening under the covers, but many SA's admit struggling when it comes to translating that into usable day-to-day understanding of the systems on which they manage. Just knowing how it works isn't enough to be really useful, what you need is the ability to look at the system and work out how what your seeing fits what you know.

"Solaris Performance and Tools" bridges that gap. Every page, cover-to-cover is filled with practical examples and explanations of the tools that let you actually see what Solaris is doing. If you've tended to rely on only a handful of tools such as vmstat, iostat, netstat, sar, and prstat, then you really want to get this book and start digging much deeper. Even as a Sr Admin I found that there were wonderful tools available that I didn't even know existed (such as "intrstat").

In particular, this book unlocks two powerful tools in Solaris 10 that can be as complex as they are powerful: DTrace and mdb. Both of these give you unparalleled power to dig your fingers into the system, but using them beyond simple one liners is more difficult than most people admin. This book gives you a great step-by-step approach to learning both. While a one-line DTrace script found in a blog might help you here and there, you won't truly understand how powerful DTrace can be untill you've built
a firm foundation on which to build your own. This book is the best way to jump start that process.

This truly is the only book available that opens the window to whats possible in Solaris in such a practical way. You'll find things you didn't know, you'll start understanding how things work by putting practical numbers on YOUR system together with the knowledge you aquired from "Solaris Internals" and you'll start solving problems rathan than just knowing why somethings broken or slow.

Every Solaris SA should have a copy of this book on their desk for quick and easy reference. Stop guessing, start knowing.

Free eBooK : Solaris 9 Administration: A Beginner's Guide

Solaris 9 Administration: A Beginner's Guide

This book certainly contains a lot of information. Nobody can question that the author is informed. For me, this book fell short of the mark because the good info was often buried in needless chatter.

I've worked as a Solaris Admin for many years and I've read a LOT of Solaris books. This book isn't the worst book ever written. But it falls into a general pattern that is common for books of this type.

First off, this book is meant to be a guide for Beginning Sys. Admins. The same author already has a Solaris reference book. That's why it pains me that this book contains so much "reference-like" filler. Do we really need another book rehashing the origins of Unix? Couldn't they cram that stuff into an appendix and list some more pertinent background info? But I guess the publisher decides this book must contain X number of pages and the author just cuts and pastes from his other texts.

There was also excessive redundancy in this book. The same run-level chart that appears in the first secion reappears in the third.

The writing style is wordy and unpractical. I too got my start in Unix in a university lab, but System Administration is about doing a lot in a short amount of time. Could you please get to your point without all of the prose?

And hidden in those long paragraphs were great links and commands. But this book wasn't well structured to have those things stand out. Instead, only somebody who has a LOT of time to read every single word can truly garner all the information in this book.

A lot of people clearly like to read wordy academic style unix books. Perhaps it's only the books title that's a problem. Still I think the book could have at least been laid out a lot better. I also would have thought it better if it had shorter more clearly focused sections that actually had to do with administration.
