Tuning your DB2 System with the Buffer Pool Tool (pdf
This presentation will
take you through the steps of analysis and tuning
using the industry standard Buffer Pool
Tool for DB2 from Responsive
Systems, and show you how to analyze and tune your system, and evaluate
the payback. Converting I/O savings to elapsed time, dollar savings, and
Aside from the elapsed
time and cpu savings from I/O elimination, the tuning process often
highlights significant application performance problems. See the steps of analysis
and tuning using the industry standard Buffer Pool Tool for DB2, how to
analyze and tune your system, and evaluate the payback.
Converting I/O savings to elapsed time, $ savings, and improved productivity. Buffer Pool Tool is the only product that can predict the I/O rate per second. This is a measurable metric. Unlike Hit Ratios, it can be converted into CPU costs, and elapsed time savings for both online and batch functions.
DB2 Version 9 Automatic Pool Tuning
(pdf - 64K) - IBM documentation for DB2 V9 has a paragraph about Automatically Managing Buffer Pool Size.
We look at their statement, and determine if the average installation will
derive a benefit from this approach, and what side-effects may occur (e.g.

DB2 Buffer Pool Tuning: Statistical Accuracy of Performance Prediction
Techniques - (.PDF by Dr. Bernie Domanski - requires
the free Adobe Acrobat Reader) Unless you're careful, it's easy to build bias
into performance prediction. This paper clearly explains the
problem, and points out where bias distorts performance results in other
Tuning the IMS Database Buffer Pools -
A presentation that extends our
industry standard Buffer Pool
tuning technology to the IMS database marketplace. See how it predicts
the effect/benefit of pool changes by altering the number of buffers and
moving datasets, grouping by access type.|
Pool Tuning - The Techniques That Work
(.PDF by Joel Goldstein - requires
the free Adobe Acrobat Reader)
- What to do to reduce elapsed times, save CPU cycles, and to optimize
and the Need for Speed (.PDF by Joel Goldstein - requires
the free Adobe Acrobat Reader)
- Simply stated, DB2 response time is never fast enough unless it's
sub-second. IBM has said that productivity improves by 100% when
improving response time from 2 seconds to less than one second. Joel's
presentation reviews what you can do to achieve better response times.
Miracles via DASD Activity Tuning (.PDF by Ivan Gelb - requires
the free Adobe Acrobat Reader)
- The z/OS environment IO activity tuning opportunities can produce
results that seem like miracles. Productive capacity of a complex can be
greatly increased because IO activity tuning will also improve processor,
main storage and virtual storage utilization. This presentation will
demonstrate all that is needed for an effective IO activity tuning project
along with the benefits achieved by such activities.
Buffer Pools and DASD Analysis and Tuning (.PDF by Joel Goldstein - requires the free Adobe Acrobat Reader) - This presentation addresses the architecture and functionality of buffer pools, and the DASD from different vendors. It illustrates proven approaches for pool tuning as well as explaining the thresholds, performance exceptions, and the meaning of vital values and percentages. There have been many changes in DASD implementations over the last several years. While its important to understand the underlying changes, it is just as important to understand the different implementations to get beyond the salespersons hype, and to understand the approaches that will provide good performance, and those that will fail.
UDB for z/OS Performance - The Basics - Performance is critical
for an enterprise. Joel's presentation reviews the what's, where's and why's
of DB2 performance.
System Performance Metrics Revisited - DB2
is a complex database management system, that has a major impact upon your
overall processing environment. Installations
are constantly looking for ways to measure, analyze, and control its
resource consumption. This
presentation assumes that the reader has a basic understanding of DB2, and
does not define basic DB2 terminology.
It addresses the origins and data available for analyzing, tuning,
and tracking the performance of the DB2 System, and inter-dependencies and
relationships between the various data elements.
Many of the system tuning options are explained and trade-offs
discussed, since the systems and applications are always somewhat different
for each corporation.
Buffer Pool Tuning: Top Down or Bottom Up? - Joel examines
different approaches for tuning DASD as well as for Buffer Pool tuning.
