SW747: Using IBM Workload Simulator V1.1 to Test z/OS Applications

27 July 2005

This Web-based training course is based on I BM Workload Simulator Version 1.1. It explores options and methodologies used for the creation and execution of test scripts which will simulate both 3270 and TCP/IP network traffic that access such disparate systems as:

• IBM Customer Information control System (CICS)
• Legacy applications that depend on 3270 terminal interfaces
• Non-relational databases such as IBM Information Management System (IMS)
• Relational databases such as IBM DB2
• MQ
• Java TCP Server
• Linux TCP Server

This course gives background on WSim testing, with particular emphasis on WSim Test Manager (WTM). It briefly discusses types of testing and the WSim testing processes, but the focus is primarily on using WTM to build, execute and report on the results of testing.

The course consists of seven core modules plus an introduction and a summary module. All modules have a lecture in the form of an independent reading. You can read the pages that comprise a lecture from your Web browser or download a PDF document to print and read offline. Most core modules have a self-assessment quiz at the end. Two modules also have demonstrations that you can view in your Web browser:

Summary

Audience

This course is designed for:

• Anyone interested in obtaining basic knowledge of Workload Simulator (WSim)
• Persons responsible for developing test plans
• Persons responsible for testing mainframe applications
• Persons using WSim on a daily basis
• Quality Assurance Managers
• Persons responsible for mainframe Systems Performance
• Persons responsible for mainframe System Capacity

Objectives

After completing this course, students should be able to:

• Explain what WSim is and what types of testing it can be used for
• Describe the main organizational elements of WTM
• Set up WTM
• Capture, create and run 3270 based tests
• Set up a test project and modularize testcases
• Run tests in both online and batch modes
• Understand the basics of WSim test script programming
• Create and run a WSim TCP client testing a Linux based TCP server

Prerequisites

• This course is indented for persons: who have the ability to use z/OS TSO/ISPF functions without assistance. This course does not require you to have previous programming background

System requirements

• This course requires Microsoft® Internet Explorer version 5 or greater

Duration

This self-paced Web-delivered course is divided into nine modules each of which contains a lecture in the form of an independent reading. Most modules also contain a quiz for self-assessment. Two contain demonstrations (seven demonstrations in all). The time required to complete it depends upon your reading speed and how many modules you complete. Each lecture usually takes between thirty and forty-five minutes to read. Demonstrations typically last between five and ten minutes. Completing the quiz for each module may take another two or three minutes. Therefore, you can allow an average of forty-five minutes for each module.

One benefit of a self-paced course is that you can take it a portion at a time. Allocating some time each day for a week may be more a effective approach to completing this course than setting aside an entire day.
