Terry Purcell is a senior software engineer in the DB2 for z/OS SQL Query
Technology Team with the IBM Silicon Valley Lab. Terry has more than 13
years experience with DB2 in Database Administration and application
development, and is a regular speaker on SQL performance and query
optimization at DB2 conferences worldwide.
These are all focused on DB2 for z/OS.
Stabilizing Access Paths Across Rebind
Every new DB2 release, maintenance upgrade, or just running
RUNSTATS brings the opportunity for changes in access paths after
your next static SQL rebind or dynamic SQL execution. Even
though the vast majority of SQL shows equal or better
performance, we are still measured on the number of failures
rather than successes. How can you safeguard yourself against
access path regression so that you don't dread the upcoming
Causes of access path instability
Limiting exposure to instability
Access Path Backup
DB2 z/OS Optimizer: What have you done for me lately?
You can always read about the features/enhancements of a new
release, such as DB2 9 for z/OS, in the manuals, in redbooks or
by attending highlight presentations. But what you generally
miss from these sources is the answer to your question, "Why do
I care about these enhancements?". And if there is one key DB2
focal area that needs extra explanation, it is the optimizer.
This presentation will deep dive into some of the key SQL
performance enhancements delivered recently in DB2 for z/OS.
Highlights in DB2 V8 for SQL performance and optimization
New enhancements in DB2 V8
DB2 9 enhancements added to DB2 V8
Highlights in DB2 9 for SQL performance and optimization
Less publicized enhancements in DB2 9
Tuning your SQL to get the most out of zIIPs
The largest percentage of zIIP redirect is reserved for the
parallel child tasks of your queries. So how do you encourage
your queries to run in parallel? This session will focus on the
table and index design requirements to exploit parallelism in DB2
V8 and DB2 9 for z/OS.
