Title: Db2 z/OS Lies, Damn Lies, and Statistics
Abstract:
..Lies, damn lies, and statistics… ‐ Benjamin Disraeli, Prime Minister of England (1868, 1874-1880)
The above line may, or may not, have been spoken well over 100 years ago, but the need for statistics and, above all else, accurate statistics is more important than ever in the Db2 world of today. Bad statistics is the number one reason for bad access paths! How could that happen; well usually bad timing is the number one reason, followed by manually updated stats and then forgotten about. There are various features and enhancements for both static and dynamic SQL delivered with Db2, but unfortunately still no common way to fallback.
This presentation explains Db2s Optimizers behavior and discusses the pros and cons of Plan Stability and Stabilized Dynamic Queries. It additionally introduces your lifesaver when your critical access path goes ballistic, a simple and solid “RUNSTATS recovery”. The basis is a complete copy of all productive required statistical data in the Db2 catalog. This should be regularly executed and the data saved away. The best way to do this is to use a Generation Gengroup which automatically stores multiple “copies” of the data.
Topics:

  • Db2 RUNSTATS basics
  • Catalog tables and Columns used for access paths
  • IBM recommendations through the ages : from Db2 V3 to Db2 12
  • Db2 RUNSTATS advanced
  • SYSCOLDIST explained
  • RUNSTATS real world Q&A: use of SAMPLE, COLGROUP, PROFILE, REOPT (ONCE), TABLESAMPLE SYSTEM, HISTOGRAM, …
  • RUNSTATS reversal

Audience experience Level: Beginner, Intermediate, Advanced

  • Visualization
  • Data virtualization (federation to non-Db2 data sources including IMS and VSAM)
  • Dash boarding
  • Graphical ad-hoc query capabilities
  • All the while enabling users to leverage their existing legacy QMF assets

In this session Frank Fillmore will provide 1. a case study on migrating twenty-year-old QMF assets to QMF Analytics v11 2. an overview of the features of QMF Analytics v11 3. a live demonstration that includes new updates to QMF's data visualization interface
