  9:00 - 10:15 SQL Performance Tuning in the Digital World
  Sheryl M. Larsen, BMC Software

New access paths, size limits, and new features can change the way you look at tuning your DB2 workloads. Add the digital forces attacking our workloads and you got a recipe for disaster if you are not prepared. Come hear about some old and new tuning techniques like adding math, empty data, creative table expressions, applying hints, and profiles that can get you ahead of the learning curve. See what new attributes your SQL tuning solutions should to have to keep up with the frantic pace of business today.

Objective 1: Understand what new DB2 features will change the way we tune queries.
Objective 2: Understand what external forces will change the way we tune queries
Objective 3: Learn the 5 ways to make queries go faster
Objective 4: Learn what the long term implications are in using hints and profiles
Objective 5: Understand the attributes of a modern SQL tuning solution

  10:15 - 10:30 Coffee Break
  10:30 - 11:45 Explain Yourself and Avoid Performance Problems
  Jim Dee, BMC Software
  Are you getting the most out of EXPLAIN, and are you doing everything you can to help the DB2 optimizer do its job? This presentation helps you answer these questions. IBM has made many enhancements to the EXPLAIN command and parts of DB2 around it, in DB2 10 and 11. This presentation goes into some of these changes and how you can take advantage of them to help the DB2 optimizer and get the best performance out of your DB2 applications.
  11:45 - 12:30 Lunch
  12:30 - 1:45 Save CPU with z/OS Large Page Frames and DB2 Page Fixing
  Dave Powell
  Save MIPS by reducing TLB misses and lower CP and zIIP CPU time from avoiding page- fix and page- unfix operations and improve response time.
  1:45 - 1:55 Break
  1:55 - 2:15 DB2 12 LOB Compression
  Daniel Kim, IBM
  DB2 12 delivers LOB compression through zEDC express. This session covers how this feature works and shares the latest performance evaluations on this feature.
  2:15 - 2:20 Break
  2:20 - 3:40 DB2 11 and 12 Top Performance Features
  Akiko Hoshikakwa, IBM
  This session covers selective DB2 11 topics and 12 system performance features. DB2 11 features include the buffer pool simulation and its usage guide. Then we will discuss key performance features in DB2 12 that you should look forward when you are planning for DB2 12 migration. DB2 12 topics include the performance improvement by exploiting larger system memory. A fast index look up in memory is automatically created to speed up random key loop up. DB2 z/OS can insert 10 million rows per second utilizing in-memory look up to avoid space search in a new insert algorithm. Just as previous versions, the range of improvement varies depending on the workload characteristics. This session will help to set the right expectation for your workloads and what actions are needed or recommended to fully utilize DB2 12 improvement.
