WebSphere Application Server for z/OS V6: Problem Documentation and Diagnosis

Prerequisites:

OS/390 or z/OS system programming experience
experience with installing and administering a WebSphere for z/OS platform,
or have attended equivalent education (ES68)
experience with using IPCS on OS/390 or z/OS is nice to have

Course Description:

This class should provide a student with the basic skills needed to do problem
determination and problem source identification for software errors occurring
in the WebSphere for z/OS V6 environment. The class starts by discussing the
resources and overall methodology needed to optimize WebSphere debugging.
It continues with a look at debugging approaches based ion problem type.
Then the largest section of the class covers the practical tools for collecting
structured diagnostic data on WebSphere for z/OS problems, and describes how to
analyze the output data to debug the problem encountered.

Two thirds of the class time consists of practical lab exercises which apply
the techniques discussed to debugging real applications.

This course is suitable for System programmers or administrators with a good practical knowledge of
administering OS/390 or z/OS systems who are responsible for problem resolution
in a WebSphere for z/OS environment.

After completing this course, you should be able to:

• Apply a problem determination methodology to solving WebSphere for z/OS
  problems
• Identify the technical skills needed to institute that problem determination
  methodology
• Format problem symptoms and diagnostic data so as to ensure that IBM software
  support can provide the greatest benefit in resolving a problem
• Identify the key components and functional areas in a WebSphere for z/OS
  runtime that most affect problem resolution
• Recognize the relevant symptoms of a problem and use them to direct debugging
  strategy
• Apply IBM recommended diagnostic flow charts to simplify problem solving
• Implement and use the relevant technology to assist in debug including
  applicable commands, tools, traces, logs, and dumps
• Apply problem avoidance techniques to minimize the chances of problems
  occurring during installation, migration, application deployment, and
  runtime execution in WebSphere for z/OS

This course includes the following modules:

Introduction to WebSphere for z/OS Debugging

• Problem Determination (PD) Resources
• Problem Areas in WebSphere Technology
• Using Problem Symptoms to Guide WebSphere Troubleshooting
• Tools and Utilities for WebSphere PD
• Problem Avoidance Techniques
