  8:30 - 9:00 Registration
  9:00 - 10:15 How In-memory Database Technology and IBM solidDB Complement IBM DB2 for Extreme Speed
  Joan Monera-Llorca, IBM

In 2008, IBM introduced in-memory database technology known as solidDB. This presentation includes a technical deep-dive of in-memory database technology; how it works, including storage algorithms and architectures, compared to conventional, on-disk databases; and why an in-memory database is faster than an on-disk database, even when the latter caches all data into main memory. There will be an architectural overview of IBM solidDB to show how it integrates with DB2 and can be used as a cache to complement DB for accelerated response times and increased transaction throughput. If time permits, several use cases will be explored.

  10:15 - 10:30 Coffee Break
  10:30 - 11:45 XML - A Technical Overview
  Bill Arledge, BMC Software

DB2 on z/OS becomes a hybrid data server with the DB2 9 release, providing comprehensive support for XML. XML (eXtensible Markup Language) is a key enabler for Electronic Data Interchange, allowing unstructured data to move within and across organizations. This presentation will clear the air about XML, describing fundamental concepts as well as details about XML support in DB2 9, including XML tablespace structures, specialized indexes, and SQL access to XML data.

  11:45 - 12:45 Lunch provided by BMC Software
  12:45 - 2:00 Exploring the DB2 Directory
  Bill Arledge, BMC Software
  Metadata information stored in the DB2 Catalog is very well known and easy to interrogate using SQL. However, at run time, DB2 makes extensive use of the other primary DB2 system database, the Directory or DSNDB01. This presentation describes the contents of the Directory, explains how to look at its contents, and discusses how you can improve your overall system performance and recovery times by paying a little more attention to this often forgotten resource.
  2:00 - 2:15 Break
  2:15 - 3:30 SQL Optimization & Access Paths: What's Old & New
  David Simpson, Themis, Inc.

Some things with SQL optimization have been the same for a long time. Other things are changing rapidly with the introduction of Version 8 and 9. This presentation reviews the basics of access path analysis with an extended discussion of what's new in the latest releases of DB2. The appropriate places for Visual Explain and Optimization Service Center will also be covered. Let's talk about what's old, what's new, and how to make the optimizer work for you.
