Description
The Definitive Solutions-Oriented Guide to IBM® DB2®
for z/OS®: Now Fully Updated for Both v9 and v10! Empowering developers on knowing what to do and where to look
in resolving performance problems in queries or programs Providing many programming and SQL coding examples Establishing standards and guidelines that lead to
high-performance SQL Implementing time-efficient code walkthroughs to ensure that
your standards are followed Focusing on the small number of SQL statements that consume the
most resources Identifying simple solutions that deliver the most sizable
benefits Optimizing performance by rewriting query predicates more
efficiently Providing a better understanding of SQL optimization and
Runstat statistics Recognizing opportunities to tweak your code more effectively
than the Optimizer Optimizing SQL code with COBOL applications Efficiently checking for the existence of data, rows, or
tables Using Runstats’ newest capabilities to consistently
optimize paths to data
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.
