Seminar Abstract:
Fact - WebSphere, Java, J2EE, and web services are not just the latest fads. They are the foundation for future e-business workloads on zArchitecture. The majority of all new workload growth on the z/Architecture platform can be attributed in some way to Java, web serving, web application serving, and web services.
Fact - Understanding just your 'MVS', CICS, TSO, DB2, and IMS is no longer sufficient. To meet your service level objectives you now need to ensure optimal performance from your e-business environment, including your web applications and e-business workloads.
Fact - z/OS web application serving using WebSphere, and associated e-business workloads will be part of your z/Architecture environments and consciousness from now on.
Fact - If you are looking for that base understanding of these relatively new technologies, as well as an assortment of performance recommendations, then this seminar is for you.
This 4.5 day seminar, developed and taught by Peter Enrico, will help you gain that required knowledge and understanding of e-business performance analysis in a z/Architecture environment. This seminar will teach you the basics of z/OS Java, J2EE, web application serving using WebSphere for z/OS, and web serving using the IBM HTTP Server.
Having worked extensively in the MVS performance measurement and tuning area, and with Java and WebSphere on z/OS, as well as significant UNIX System Services application porting and benchmarking projects, Peter Enrico draws from his wealth of experience to help you understand the e-business performance on z/OS of Java, J2EE, WebSphere, HTTP Serving, Web Services.

Seminar Highlights:
The seminar begins with an overview of e-business environment on zArchitecture.
Next you will learn both the basics of Java on z/OS and the J2EE architectural standard. Most newly developed e-business workloads are developed in Java, and by attending this seminar you will gain a key understanding of how Java is implement on z/OS and about Java performance management and tuning. You will also learn the basics of the J2EE standards. An objective of this section of the seminar it ensure you can attend any web application implementation meeting back at your shop, and feel comfortable participating in the discussions and plans. This usefulness of the J2EE section of the seminar has drawn especially high praise from past attendees.
Once the foundation has been laid, you will then learn about the zArchitecture e-business environment and system components that make up the MVS web-serving environment. You will gain a working knowledge of the major USS and e-business facilities as they relate to the zArchitecture platform. This section of the seminar provides an overview of the IBM HTTP Web Server, WebSphere Application Server for z/OS, WLM management of web workloads, Java, LDAP, and a variety of other facilities and components that make up the z/Architecture e-business environment. Options for Linux on zArchitecture are also discussed. You will also learn the configuration options for WebSphere applications.
A portion of this seminar will also be devoted to providing an understanding of Web Services. You will become familiar with the objectives of XML, DTD, SOAP, WSDL, UDDI, and more.
The seminar then proceeds to help you develop a working knowledge of performance measurement and management of web workloads on z/OS. You will learn about the available WebSphere measurements, the flow of WebSphere transactions, and how to monitor and tune WebSphere workloads. This section includes the IBM HTTP Web Server, WebSphere Application Server (SE and EE), WLM goal mode evaluation for web workloads, and tuning tips for other components associated with web serving on the zArchitecture platform.
Performance measurements, analysis, and tuning considerations are discussed throughout this seminar. A key strength of this seminar is that Peter does not just teach tuning recommendations, but why each recommendation is exists. All seminar materials have extensive notes for later reference.

Seminar Particpation:
Prior to the seminar, enrolled students will be sent a note suggesting what configuration data, parameter members, and what measurement reports should be collected and brought to the seminar. The purpose of this information is two fold. First, it ensures that each attendee is familiar with their current or planned USS, WebSphere, Java, and e-business environment. Second, parameter members and reports brought to the seminar will be discussed and could be used to reinforce concepts learned. Peter is available before class, during breaks, and after class to discuss with each student their own environment

Seminar Outline:
The following is a high level outline for this seminar. A detailed seminar outline is available upon request.
Part I: Introduction to e-business and e-business components on z/OS
Web serving and e-business on zArchitecture is a very broad area of study. This section of the seminar provides an overview of the primary e-business components and terminology.
