Understanding WebSphere in a z/OS Environment

What you will learn

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.
