This is a book you should own. At 19 chapters and 464 pages it's not a huge
book, but there is no better reference to have on the shelf. Those chapters
cover everything from capacity planning to performance monitoring to tuning
query performance at a very low level. The discussion of when to use RAID-5 vs
RAID-10 is the best I've read. Not just theory, this book has the numbers and
formulas to back up the theory! Another part I was pleased to see was a good
discussion of when to use the various boot.ini flags (/3GB and /PAE) to support
using additional memory over the standard 2g limit.
The performance monitoring sections are done well. Lots of information about
what the counters mean. For example, the system object has a context switches
counter - do you know at what point you should be concerned and as easy way to
reduce them? Answer: 10,000 per second, change the lightweight pooling option to
1. It also contains some great suggestions such as keeping at least one backup
on disk, so that if you need to restore you can begin immediately compared with
waiting on the tape drive. Not rocket science, but an important point to make in
any discussion of backups and not always obvious to new users/DBA's.
One other useful tip I picked up was about versioning stored procedures. You
can create two versions of the same procedure like this:
create proc usp_test as ...........
create proc usp_test;2 as .......
Then when you execute, if you just type usp_test you get the first version by
default. But you can execute "usp_test;2" to run the other version.
Have to think I'll find that useful for a few things!
I was disappointed not to see coverage of functions, both in terms of
performance tuning/considerations as well as more subtle things like the use of fn_trace_gettable
to load a trace from a file into a table for analyzing. My only other complaint
is not getting an e-version of the book on CD (book does not include a CD) so
that I find something quickly that may not be included in the index.
Microsoft Press does a great job of giving you a snapshot of the book, follow
this
link to see a complete listing of the table of contents, index, and a sample
chapter. I'd like to note that if you're still using SQL 7 there is an earlier
version of the book that I highly recommend as well. Sells for about $35 at
Amazon. Our thanks to Microsoft Press for providing us with a review copy -
we'll be giving it away to a lucky reader in an upcoming contest!
I'll rate this one four stars out of five.
