Autumn CCMG Membership Meeting & Agenda
Radisson Hotel, Cromwell - Friday, October 15, 2004
--------------------------------------------------------------------------------
Our October meeting is always a fun and informative day in the middle
of the New England autumnal splendor. What better way to enjoy life than
to take part in a fabulously full day of terrific topics, engaging speakers,
and educational opportunities at a fraction of what you or your company
would typically spend for a workshop or seminar.
Connecticut CMG has been very fortunate over the years to have industry
honored speakers come from all over the country to this Northeast corner
to share their knowledge and special expertise on the most pressing needs
of our work. This meeting achieves our highest goals in bringing to our
members both leaders in our field and topics that challenge all of us
everyday.

Agenda Abstracts
Workload and Capacity Planning Track
09:00-10:15 Workload Manager—Our Experiences Implementing DB2 Stored
Procedure Management
Len Jejer – Hartford Insurance Group
Ray Smith – Hartford Insurance Group
This presentation relates our experiences, good, bad and the ugly of implementing
WLM-managed DB2 Stored Procedures. It is a continuation of the presentation
on converting to Workload Manager response time goals for our CICS and
IMS online transaction environments. This next chapter of the story.
If time permits we will touch on our work on IRD CPU management and WLM-managed
JES3 initiators.
10:30-11:45 A Finger in the Wind: Forecasting Techniques for Capacity
Planning
Linwood Merritt – Bank of America
Robust capacity planning entails the analysis of data to project future
demand. This analysis can be as simple as a linear trend of historical
demand data, and can be as complex as multivariate regression using business
drivers combined with analysis of changing business functionality. This
session explores the use of Excel and SAS to perform simple trend analyses
of computer resources and produce capacity planning forecasts.
Performance Track
09:00-10:15 Developing and Applying a Distributed Systems Performance
Approach for a Web Platform
James Cusick – CT Corporation
This paper describes the steps taken to develop and apply a performance
engineering model to an existing commercial web site. The approach to
developing the performance model is presented along with the detailed
results of the baseline and test data. A metric is developed to determine
the transaction cost of orders being placed on the system. A comparison
of forecasts to actual performance results is also presented.
10:30-11:45 The Performance Impact of Security Attacks on Enterprise
Computing
Dr. Pierre M. Fiorini, - University of Southern Maine
This session considers the following issues from enterprise performance
assurance perspective: 1) How can performance analysts and capacity planners
assess the impact on the performance of applications during a security
attack? and 2) How systems can be designed and configured so that Quality
of Service (QoS) objectives can be met during a security attack for mission
critical applications. We develop analytic techniques that can ascertain
performance measures for a wide class of computing systems when security
attacks occur.
Combined Sessions
12:45-2:00 Confidentiality Implications for Web Transaction Measurement
and Monitoring
Alistair Croll – Coradiant
Balancing the need for effective web transaction performance management
while meeting compliance and confidentiality regulations is a key challenges
that organizations face. Privacy requirements and stringent regulations
such as GLBA and HIPAA affect a broad spectrum of organizations. Can you
effectively monitor web performance and comply with regulations when transactions
include secure and confidential data? This session looks at approaches
that satisfy security requirements while providing access to business
relevant performance data.
2:15-3:30 Workload Characterization for Websphere Application Server
Yefim Somin, BMC Software
WebSphere Application Server is a complex Java-based environment widely
used as a business tier for critical applications accessed through the
web. It is important to understand what resources are consumed within
WebSphere by different types of business activities. Using OS level process
information or other non-process statistics presents certain problems.
The session discusses benefits and problems inherent in various approaches.
