Understanding WebSphere in a z/OS Environment


This course introduces the world of WebSphere in z/OS environments, and introduces and explains the WebSphere Application Server for z/OS from the perspective of the experienced mainframe professional.
This course is particularly appropriate for all applications architects, project managers, programmers and administrators who are going to encounter web applications in their environment.

This course is available for one-company, on-site presentations and for live presentation over the Internet, via the Virtual Classroom Environment service.

Objectives

On successful completion of this course you will be able to:

  • describe WebSphere at a conceptual level
  • understand the terminology used in WebSphere environments
  • describe the role of WebSphere Application Server
  • describe the set-up of this environment under z/OS: web, web applications, web servers, etc.
  • explain the role of Java and the importance of an architecture combined with application components
  • discuss the relationship of WAS to z/OS.

Who Should Attend

Application architects, project managers, programmers, technicians and administrators who are going to be exposed to web applications in a z/OS environment.

Prerequisites

An understanding of the z/OS environment at a conceptual and terminological level is expected. Some familiarity with the Internet and the Java environment is an advantage, but is not mandatory.
