Oracle SQL Tuning Pocket Reference
by Mark Gurry
Practical Oracle Database Tuning Guide That Provides Best Overall Return
One of the most important challenges faced by Oracle database
administrators and Oracle developers is the need to tune SQL statements
so that they execute efficiently. In this book, Mark Gurry shares his in-
depth knowledge of Oracles SQL statement optimizers. Marks knowledge
is the result of many hard-fought tuning battles during his many years of
providing Oracle tuning services to clients. Mark provides insights into the
workings of the rule-based optimizer that go well beyond what the rules
tell you. Mark also provides solutions to many common problems that
occur with both the rule-based and cost-based optimizers. In addition to
the specific problem/solution scenarios for the optimizers, Mark provides a
number of handy SQL tuning tips. He discusses the various optimizer
hints, telling you when they can be used to good effect. Finally, Mark
discusses the use of the DBMS_STATS package to manage database
statistics, and the use of outlines to specify execution plans for SQL
statements in third-party applications that you cant otherwise modify.

Personal Review: Oracle SQL Tuning Pocket Reference by Mark
Gurry
Yesterday, I saw this pocket book, then I decide to buy it because...
* Clear clarification on which optimizer (cost-based and rule- based) is
used for a specific situation and its problems.
* Sorts, indexes, IN/EXISTS, OR/UNION, Loop, joins with tables...etc
related performance issues and rating , giving a reader a reminder on the
criteria to write a well-performed SQL.
* What is bad SQL?How to use SQL Hints?
* How to analyze table with DBMS_STATS package?
* How to pre-define outline for your execution plan ?I have bought DBA
checklist and Oracle with UNIX, they are my nice partners as well. Haha...I
still remember I deal with a staging database problem in my work, I cannot
find a solution from a THICK and HEAVY book but from them.If you need
handy guides, pocket references are excellent and light, haha...I want to
buy RMAN reference later :D, they seem a series of fiction.
