Meeting Schedule:

8:30 - 9:00	Registration

9:00 - 10:15	Rev up your SQL Applications with Enhanced Statistics
	Ken McDonald, BMC Software

	You may have heard that Enhanced Statistics were added to DB2 for z/OS with DB2 9, and you probably wondered what they are and how they can help. This presentation will answer your questions about what the statistics are, how they are enabled, how they get collected, and what effect they will have on your SQL execution. Session objectives: What statistics are affected by the STATCLUS DSNZPARM parameter in DB2 9? What improvements have been made to the calculation of cluster ratio? What does Data Repeat Factor mean and how is it calculated? When are the enhanced statistics used by the DB2 optimizer? What can you do to exploit these statistics to improve the performance of your SQL applications?

10:15 - 10:30	Coffee Break

10:30 - 11:45	The Online Schema (R)evolution
	Ken McDonald, BMC Software

	The latest improvements in Online Schema capabilities introduced in DB2 10 for z/OS represent something more like a Revolution rather than an enhancement to the OLS Evolution capabilities we've been used to seeing in successive releases of DB2. For the first time DBAs can register the changes they wish to make and then implement them at a time of their choosing using an Online Utility rather than having the object concerned move into an Advisory Status which may cause serious Performance Issues or worse. This session will describe the new OLS capabilities, how to use them and some pitfalls which may not be immediately obvious when you read the new features list. Come and listen to the way of the future as far as making Changes to your DB2 database structures is concerned! Session objectives: Explain the limitations in OLS capabilities provided in previous releases of DB2 Describe what has been delivered in DB2 10 for z/OS with the new Deferred Alter capability Discuss how to use the new feature in a real life environment including overcoming any pitfalls or gotchas that may not be obvious from the release notes Provide an Online Schema Change Checklist that delegates can use back at the ranch What's still missing and what may be coming next (bearing in mind that I don't work for IBM!)

11:45 - 12:45	Lunch

12:45 - 2:00	DB2 for z/OS Stored Procedures - Trends and Technology
	Robert Catterall, IBM

	Stored procedures have been widely used for years in DB2 for Linux, UNIX, and Windows application environments. On the mainframe side, adoption of the technology was initially more limited, but it is becoming mainstream now, in part due to the advent of native SQL procedures, delivered with DB2 9 for z/OS and enhanced with DB2 10. This presentation will lay out a vision of a modern DB2 data-serving system in which stored procedures play a very important role. It will also provide a review of DB2 for z/OS stored procedure enhancements, with a particular emphasis on the advantages of native SQL procedures. The presentation will conclude with some hints, tips, and go-forward recommendations.

2:00 - 2:15	Break

2:15 - 3:30	The MOST VALUABLE Information I Get From DB2 for z/OS Monitor Accounting and Statistics Reports
	Robert Catterall, IBM

	Online monitoring of a DB2 for z/OS subsystem is very useful at times, but to REALLY see "what's going on in there" I rely on the accounting and statistics detail reports that a number of DB2 monitoring tools can generate. Drawing on my 20+ years of experience in analyzing and using the information in DB2 monitor reports, I will describe in this session the report fields that contain the highest-value information, and how I use them.
