Peter Enrico

Peter Enrico, of Enterprise Performance Strategies, Inc., has strong and diverse experience with the IBM S/390 and zArchitecture platforms, and a solid background in Workload Manager, WebSphere, Java, J2EE architecture, and Web Services on the zArchitecture platform. His expertise extends to OS/390 and z/OS performance management, Parallel Sysplex, UNIX System Services, and the many components of e-business performance on MVS.

Peter Enrico is a well-known and effective lecturer and seminar instructor. He teaches on a wide array of topics including Workload Manager, WebSphere for z/OS, basic MVS performance, Parallel Sysplex, UNIX System Services, and much more. His classes include WLM Performance and Re-evaluation of Goals, S/390 Java, J2EE, Web Serving and WebSphere on z/OS Performance, and Essential z/OS Performance Tuning. All have drawn great praise from a wide variety of customers and corporations.

Peter is a regular speaker at SHARE, IBM's zOS Expo, both national and regional CMGs, and a variety of international conferences.

Dan Squillace

Dan Squillace is the Mainframe Support Manager at SAS Institute where he has worked for the past 20 years in several positions in both R&D and Information Systems. He has considerable experience in performance and capacity planning for both mainframe and distributed systems. Over the years, he has presented a number of papers at national and regional CMG meetings, SHARE, and SUGI.

Abstracts:

Introduction to J2EE and WebSphere Concepts
Presenter: Peter Enrico - Enterprise Performance Strategies, Inc.

This presentation will be a high level overview of the J2EE architectural standard, as well as an introduction to WebSphere on z/OS. The purpose of this presentation is to help you gain a better working knowledge of the e-business technologies, J2EE standard, and what it means to be a J2EE application server. Also included in this session will be an overview of WebSphere on z/OS and how, and why, a product such as WebSphere is needed to satisfy the J2EE standard.

So if you are curious what a Enterprise JavaBean is (and why it is not the same as a JavaBean) then you will find this session of interest. You will become familiar with terms such as JVM, Servlet, EJB, JSP, Connector, application server, web server, and many more concepts.

WLM - The Lives and Times of Transactions on z/OS
Presenter: Peter Enrico - Enterprise Performance Strategies, Inc.

z/OS allows all sorts of workloads to run on the zArchitecture platform.

But what the heck is a transaction? We've spend years analyzing transactions for TSO, Batch, CICS, IMS, USS, DB2, and started tasks. Now, however, we have transactions are entering the z/OS system from a web browser or other system, running in a HTTP Server, which in turn may drive a transaction in a WebSphere Application Server, which in turn may be drive a transaction in a back-end system such as CICS, IMS, and / or DB2. Is it possible to get a view of the transactions response time from when it enters z/OS until it completes?

This paper will explore the current meaning of transactions on z/OS, and the understanding of transactional flows, the WLM view of various transaction types, and some aspects of CPU accountability and response time components of the various z/OS transactions.

Service Level Reporting for Web Applications
Dan Squillace - SAS Institute

The speaker will present a case study based on web log data collection and reporting for a production web application. Service level reporting including response and transaction volumes by application and user, exceptions, and errors can be readily generated from log records from the edge server, i.e. the client's entry point to the web site. Further, we will show how this data is rolled up for historical performance, for usage trends, and as the user-oriented unit of work component for capacity planning.

Sponsors:

Enterprise companies face the requirement to align IT resources with the needs of the business in order to ensure the successful performance of business critical applications. Not only are IT organizations faced with meeting the performance requirements of these applications, they must also optimize the utilization and cost of the IT infrastructure. The HyPerformix solution helps reach this alignment; providing the decision-support tools to understand end-to-end application performance and predict the effect of changes BEFORE they are made. The benefits of the HyPerformix solution include: reduced risk of deploying enterprise applications, avoidance of unnecessary IT spending, optimization of IT infrastructure, revenue protection, and improved time-to-market. HyPerformix is a leading provider of performance and capacity planning solutions for the enterprise and is headquartered in Austin, Texas.

Metron specializes in performance management, reporting and capacity planning across the enterprise. It is our only focus and has been since 1986. Athene (over 350 clients worldwide) is a true enterprise-wide performance management software solution providing measurement, analysis, planning and reporting capabilities for UNIX, Linux, Windows Servers and OS/390 or z/OS mainframe environments, as well as Oracle and SQL Server. Our Custom Data Base facility even allows other pertinent numeric time-stamped data (i.e. business metrics) to be input into Athene to be included in reports as well.
