  9:00 - 10:15 Recent changes in DB2 for z/OS Logging
  Jim Dee, BMC Software
 
 

How well DB2 handles Log data can be a critical factor in maximizing performance, particularly in a high transaction rate environment. There have been a number of changes in the area of Logging over recent DB2 releases. Some of these have been obvious improvements such as the ability to use DFSMS Striping for Active Log datasets, but there have been Logging implications in some other changes such as the introduction of Reordered Row Format. However, many sites I visit have not really investigated these changes in any detail and the impact they might have on their operations. This presentation provides an update on changes to how DB2 manages logging updates and some useful hints and tips you will be able to take away and use to review your logging environment.

 
  10:15 - 10:30 Coffee Break
 
  10:30 - 11:45 The Natives are getting Restless, an overview of DB2 Stored Procedures
  Frank Rhodes, BMC Software
 
 

Stored Procedures were first added to DB2 for z/OS back in V5. Most every release of DB2 since has added additional functionality or type of stored procedures. The different types of stored procedures have strengths and weaknesses. This presentation will provide a brief history of Stored Procedures in DB2 for z/OS, along with an overview of the schema used to create stored procedures. It will discuss the different types of stored procedures, External, External SQL and Native touching on some of the advantages and disadvantages of the different types. How can you test a new version of a Native stored procedure without affecting other executions of the active version? When it comes to deploying Native Stored Procedures across your environment, what options do you have available?

 
  11:45 - 12:45 Lunch
 
  12:45 - 2:00 Virtualize Production in DB2 z/OS with Profiles
  Jim Dee, BMC Software
 
 

Most sites understand the importance of having a performance measurement/assurance environment to validate the performance of new or changed SQL. The snag is, as DB2 gets smarter about its environment, it gets increasingly difficult to guarantee that the performance DB2 subsystem really does behave the same as the real production subsystem(s). This is why IBM have introduced Production Virtualization to "fool" a DB2 subsystem into thinking that certain aspects of its environment are actually different from reality - making it possible to model a production subsystem in a completely separate LPAR. This session looks at how this has been implemented - with a couple of dsnzparm changes and addition to the capabilities of DB2 Profiles. As always, things are never quite as simple as they might have been.

 
  2:00 - 2:15 Break
 
  2:15 - 3:30 An XML Document's Life - Dr. Node!!!
  Frank Rhodes, BMC Software
 
 

XML continues to be an emerging technology and more features are being added to DB2 to support it. So what is this new XML data type? Follow the adventures of 'Dr. Node', an XML document as he gets inserted into a DB2 table. Not only will you see how he is related to his parent row but you will learn about his hierarchical tree structure and the catalog tables involved in supporting him. You will also see how to use the new DB2 10 XMLMODIFY commands to manipulate individual nodes within Dr. Node. In order to verify Dr. Node's integrity, we will discuss the impact of the new DB2 10 Check Data syntax for XML spaces. Finally we will look at how a Reorg impacts the doc'tor'. We will end with a discussion of how things could have been different in Dr. Node's life with non-versioning versus multi-versioning, indexing with the new Date and Timestamp data types, and the new zparm value that allows for DOCID's to be randomized.
