  9:00 - 10:15 Optimizing Applications Using Extended Explain Tables
  Jase Alpers, IBM

The plan table externalizes DB2 optimizer's access path choices, but does not include the information which led to that decision. In this session, we will focus on the information contained in a key extended explain table - the predicate table - and the insight it can provide into the DB2 optimizer's decisions. Queries will be provided that can be used to mine the explain tables and catalog so that potential query performance issues can be proactively identified and resolved.

  10:15 - 10:30 Coffee Break
  10:30 - 11:45 Tuning Queries Like a DB2 Developer
  Jase Alpers, IBM

Tuning DB2 applications for optimal DB2 performance does not need to be a complex exercise. Most SQL performance problems can be easily solved by identifying and resolving differences between the optimizer's expectations and reality. In this session, we'll walk through the process used by the DB2 service team to identify and resolve access path performance problems. We'll discuss the primary reasons the optimizer "gets it wrong" along with options to correct poor performance.

  11:45 - 12:45 Lunch
  12:45 - 2:00 Achieving the Best of Both Worlds - The hybrid data server approach
  Willie Favero, IBM

Everything seems to be taking too long from tuning complex queries to giving executives access to the right analytics. The world of data and information has changed and organizations are looking for new ways to quickly exploit the explosion of information available. However, yesterday’s approach to decision systems is not meeting the need.

New access paths and a new resource manager delivered via the hybrid data server can be the answer to this challenge. The approach makes data warehouse modernization much simpler and more robust. It creates an environment for operational data store, data warehouse and analytic marts on the same platform as operational systems. This session will explore the blending of traditional techniques for query management with the usage of accelerator technology.

Topics include:

  • Building the System z foundation for analytics
  • Deploying the hybrid data server approach
  • Customer success and lab proof points
  • Traditional techniques that augment this strategy
