addresses and phone numbers).
SIRDUG will be calling or emailing a confirmation for each person who
pre-registers by the deadline. If you have pre-registered and have not
received a confirmation by the day after the deadline, please notify us as
your registration may not have been received.
If you have not pre-registered by the deadline, you may pre-register after
the deadline or register at the door, but the availability of presentation
handouts and lunch can not be guaranteed and confirmations will not be sent.

Susan Lawson is an internationally recognized consultant and lecturer with a
strong background in system and database administration, and is a principal
with YL&A. In the past, she has been an IBM Data Sharing advocate where she
supported a variety of large DB2 customers. She provided technical expertise
for migration to DB2 Data Sharing in a Parallel Sysplex environment, as well
as troubleshooting performance problems during post-implementation. She
currently works with several clients to help develop, implement and tune some
of the world's largest and most complex DB2 databases. Her other activities
have included authoring articles, presenting at user group meetings (where she
has won best speaker awards), and providing technical editing for trade
journals. She is an IBM GOLD Consultant for DB2 and S/390, and is an IBM
Certified DBA and Application Developer for DB2 UDB Version 7 for OS/390.
She is one of the authors of "DB2 Answers!" published by Osborne/McGraw-Hill,
"DB2 High Performance Design and Tuning" published by Prentice-Hall, "DB2 UDB
for OS/390 Version 7 DBA Certification Guide" published by Prentice-Hall,
“DB2 UDB for OS/390 Version 7 Application Development Certification Guide”
and “DB2 UDB V7 Family Reference Guide” published by YL&A.
Platform: DB2 for OS/390 and z/OS
Audience: DBA's, System Programmers, Application Programmers
Achieving maximum performance from DB2 requires a different approach and
stricter methodologies than simply getting a DB2 application to perform well.
In todayÂ’s web and e-business environment the rules have changed and we must
find every tuning knob in order to get another transaction through the system.
This seminar focuses on specific issues of system design, physical object
design, application design and tuning methods used to achieve high
performance. Topics such as table and index design, large tables and NPI's,
DPSIs, pushing logic into SQL, control and concurrency, enterprise wide
performance topics are examined for OLTP, batch, and data warehousing. Topics
such as buffer pool design and utilization, concurrency and locking, DB2
compression, EDM pool sizing, RID pool sizing, SORT work tuning, and
parallelism are examined, and it is shown how poor memory tuning directly
effects application performance. The performance techniques of the some of the
new object-relational SQL features are also covered. Focus is on the complete
set of design points of DB2, and how they will affect performance of your
applications. Discover why many old guidelines no longer apply, how old
standards can actually hurt us and learn the approaches to systems management
and tuning for the DB2 environment. This course gives new ideas on achieving
the new demands placed on us in today high volume/high availability
environments. The rules have changed.
The case study examples and stories told are from actual performance audits
and design/development efforts.
All topics and examples are current with DB2 z/OS Version 8.
