Mike Wingfield - Compuware Corporation
Abstract:
Mainframe Application Performance Management is more imperative today with processor speeds approaching the 7 GHZ limit. Throwing hardware at performance issues is not enough anymore. Application response
times and runtimes need to be tuned to run as efficiently as possible and often times when it’s DB2 in the application, most of the performance opportunities will be found there. Various CICS, Batch, and DDF DB2 Version 10 tuning opportunities will be examined; analyzing SQL Text, DB2 Access Paths, and the DB2 Catalog Objects involved.
* What on Mainframe Applications are Using CPU and Causing Wait
* 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

Connecting DB2 for z/OS Applications, Including Mobile and Cloud, with Data on z Systems
Paul Wirth & John Iczkovits - IBM
Abstract:
Although z Systems provides unmatched scalability, security and availability for valuable data, applications have to be able to get to that data. Applications also must be able to access the data from a variety of front-end layers, including cloud and mobile. In this session, you learn about new options for connecting to z Systems -based data, including z/OS Connect. You also learn about new ways to manage connections to a DB2 for z/OS system for enhanced performance and control.

Solving an Intermittent Production Problem Using DB2 for z/OS System Profile Monitoring
Mark Rader - IBM
Abstract:
Learn how a client using DB2 for z/OS solved a production problem by deploying System Profile Monitoring. A runaway distributed application had caused significant impact to the DB2 production environment. System Profile Monitoring allowed the client to manage the distributed threads and ensure the main DB2 environment was unaffected. System Profile Monitoring provides a variety of exciting capabilities: ZPARMs at a more granular level than the subsystem, modeling the production environment in a test environment, SQL optimization choices, and setting special registers for distributed threads - all available via online changes.
