Overview
The Definitive Solutions-Oriented Guide to IBM® DB2®
for z/OS®: Now Fully Updated for Both v9 and v10!
The largest database tuning performance gains can often be obtained
from tuning application code, and applications that use SQL to
retrieve data are the best candidates for tuning. This
well-organized, easy-to-understand reference brings together more
than 100 SQL-related skills and techniques that any developer can
use to build and optimize DB2 applications for consistently
superior performance.
DB2 tuning expert Tony Andrews (“Tony the Tuner”) draws
on more than 20 years of DB2-related experience, empowering you to
take performance into your own hands, whether you’re writing
new software or tuning existing systems. Tony shows you exactly how
to clear bottlenecks, resolve problems, and improve both speed and
reliability.
This book fully reflects the latest SQL programming best practices
for DB2 V9 and DB2 V10 on z/OS: techniques that are taught in no
other book and are rarely covered in general DB2 SQL courses.
Drawing on his extensive consulting experience and highly praised
training with Themis Inc., Tony also presents practical checklists
and an invaluable 15-step methodology for optimizing virtually any
DB2 application.
