only if you're just starting out
on October 24, 2001
After reading the other reviews I had high hopes for this book. The book is not geared to people that already have basic sysadmin skills. And in one case the book makes a rather dubious statement. They list a few ndd parameters and state "The other values should never be changed on a production system." Well, they left out tcp_ip_abort_cinterval. And they don't mention tcp_ip_abort_linterval at all which so far seems to be an undocumented Sun Microsystems parameter. A book about tuning should cover all the tunable parameters and explain cause/effect. Simply stating that you never change the other parameters without explaining why isn't why you buy a book on Performance and Tuning.
If you're just starting out with Sun administration and do not know a lot of the unix commands to administer and monitor a Solaris box this book will help. The book does cover much of the basics and background that someone starting out needs. The book does leave out a number of higher level concepts and doesn't cover all tunable parameters so it doesn't really help much beyond already available text/webpages which you'll still have to research and scour to really learn the whole story on Solaris performance and tuning. But if you already know some of what you're doing you're money is better kept in your pocket.
