  9:00 - 10:15 Application Developers & DB2 for z/OS
  Ted Alexander, President, Atlanta DB2 Users Group
 
  Things are changing with every release of DB2 for z/OS. More features for application developers to exploit and a few that are going away. In this session we will cover DB2 for z/OS version 9 and DB2 for z/OS version 10 and we'll see if we can find some stuff on DB2 for z/OS version 11.

This presentation is gear towards the application developer and the tricks that can make their application run smoothly and upgrade easier to the next release of DB2. Did you ever wonder how DB2 for z/OS new features are chosen; we'll have a look at that too. We look forward to seeing you at the session.

 
  10:15 - 10:30 Coffee Break
 
  10:30 - 11:45 Development in a Virtualized Production Environment
  Ulf Heinrich, SEGUS Inc.
 
  Trustworthy access path visualization not only shows when performance changes, but also how, why, and what it changes to. Environment simulation allows exact access path simulation on another machine showing what will happen if you switch hardware or use different configurations for CPU, I/O, or memory. Create virtual indexes and see the results without affecting your real applications. Detect and understand Optimizer choices that originate from the environment and avoid any more unforeseen application behavior when moving a new release to production. These capabilities introduce a whole new world of "what if" opportunities and especially protect you from testing that doesn’t focus on what counts: the resulting performance in your production environment.
 
  11:45 - 12:45 Lunch
 
  12:45 - 2:00 Episode 9 – The Return of the Hierarchical Empire
  Ulf Heinrich, SEGUS Inc.
 
  The integration of XML in DB2 for z/OS V9 has been called the revenge of IMS. There is some truth in this because XML is a hierarchical structure, which is now integrated into the relational model. A few questions are brought up with this, like:
  • How do we access the data in XML structures?
  • What about indexing to improve performance?
  • Are there recommendations for database design?

In this presentation, we will highlight experiences with XML integration in DB2 for z/OS. Additionally, we will provide hints and tips on how to improve performance. Last, but not least, you will see why you should recall hierarchical "thinking modes" to survive in the new fashionable XML world.

 
  2:00 - 2:15 Break
 
  2:15 - 3:30 Eenie, Meenie, Miney, Mo! Which Table (Space) Type and Page Size Shall I Choose for DB2 on z/OS?
  John Iczkovits, IBM
 
  Choosing the correct DB2 table (Space) type is requires careful analysis. Should I use a segmented table space, a universal table space (UTS partitioned by range or UTS partitioned by growth), HASH access, or a classic range partitioned table space? What about the page size? Does 4K, 8K, 16K, or 32K page size work best for my application requirements? Are there benefits to storing more than one table per table space? Are there benefits to using DB2 to compress the data? Choosing the correct attributes for by table and indexes the first time is essential to avoid costly re-work and outages. This presentation is designed to enlighten you on best practices for choosing the correct tables space types, page size and attributes for your data.
