Presentation #1:Speaker: Mike McCarthy (IBM Corporation) - "Db2 Family: New Capabilities - Mainframe to Cloud ”
DB2 has been around for nearly 35 years, being first released by IBM in 1983 for MVS mainframes. Throughout the 1990’s and beyond, DB2 became available on many operating systems including OS/2, AIX, HP-UX, Sun Solaris, Windows, Linux and even smartphone systems. Today, rebranded as IBM Db2, it supports OLTP, data warehouse, and analytics applications via deployments from mainframe to cloud. This presentation will look at Db2 deployment options, including mainframe, Windows, Linux, and Cloud. Customers looking to build new-age applications using OData, REST apis, and JSON or provide mobile access to data, can continue to use Db2 to meet new requirements.
Presentation #2:Speaker: Mike Wingfield (Compuware) – "DB2 Performance & Tuning – It’s All About The SQL!”
Throwing hardware at Mainframe performance issues is not enough anymore. Application response times and runtimes need to be tuned to run as efficiently as possible to reduce the Rolling 4 Hour Average (to lower the Monthly License Costs) and often times when it’s DB2 in the application, most of the performance opportunities will be found there. CICS, Batch, and DDF DB2 tuning opportunities will be examined; analyzing SQL Text, DB2 Access Paths, and the DB2 Catalog Objects involved.
. What’s Using CPU and Causing Wait in Mainframe Applications
. Analyzing Online and DDF SQL for Optimal Response Times
. Investigating DB2 Batch Jobs to Reduce Overall Runtimes
. Exploring Access Path Efficiency by Examining the Explain
. Scrutinizing Information Contained in the DB2 Catalog
Presentation #3:Speaker: Susan Lawson – "Reducing CPU and Maximizing Db2 z/OS Application/SQL Performance"
This seminar will cover many best practices for our applications in order to achieve performance and reduce CPU in Db2 z/OS. Many techniques to minimize overhead and locking will be explored. We will also take a look at techniques for coding efficient SQL and minimizing the amount of data we bring back to process in our applications via optimal predicates, less repetition and better use of indexes. We will also look at how to best utilize the dynamic statement cache and to use it in performance tuning efforts along with several Explain tables. All features discussed are current with Db2 11 and 12.
Presentation #4:Speaker: Susan Lawson – "Db2 z/OS Table and Index Design for Performance and Availability”
This seminar will discuss many issues surrounding alternative table and index designs for performance and availability current with Db2 12 for z/OS. We will look at many different alternatives to help design tables and indexes for the best performance possible for the type of application process and how to achieve high availability. There are many issues to consider for high volume insert and update transactions, and a balancing act to be achieved for responsiveness to readers. Table issues such as denormalization, non-column attributes, indicator columns, repeating columns, derived data, aggregated columns, table flipping, identify columns, surrogate keys, horizontal and vertical partitioning. We will also look at issues with designing VLTBs (Very Large Tables) and XVLTBs (eXtremely Large Tables), the rules have changed! Index issues such as minimizing indexes, using NPSIs or DPSI, and using indexes for best possible performance will be discussed. This seminar also focuses on utilizing features that have been introduced in the latest DB2 releases.
