Customer Master File Creating Test Data

Introduction

Using production data for testing and development is no longer seen as an acceptable practice in test and development environments. Organizations must remain compliant with current data protection requirements and government regulations. This document describes a simple process for creating test data for a customer master file. This simple process may be used with a traditional Record Sequential File, a VSAM Data Set or a Relational Data Base Table.

We have made a significant effort to ensure the documents and software technologies are correct and accurate. We reserve the right to make changes without notice at any time. The function delivered in this version is based upon the enhancement requests from a specific group of users. The intent is to provide changes as the need arises and in a timeframe that is dependent upon the availability of resources.

JCL, Manage Customer Test Files

This section will describe how to create a new customer master file with test data. This process provides a repeatable and automated process for creating test data for development and Quality Assurance Testing (QAT).

Delete/Define a New VSAM Cluster

The first step in this process is to create a new VSAM Cluster. The following is the command that will submit the job to delete/define a new VSAM Cluster.

C:\SIMOSAM1\LOADLIB>  ezSCHEDULE SIMOBATA CUSTDDJ1

The following (CUSTDDJ1.jcl) is the JCL member that will be submitted to the Micro Focus Server that has been configured to run batch jobs.

//* characters starting at the first position in the record.
//* The record length is 512 characters.

Populate a New Customer Master File

The next step is to populate the new VSAM Cluster with the Name, Address, City, State or Province and ZIP or Postal Code. The following is the command that will submit the job that will add records to the new VSAM Cluster.

C:\SIMOSAM1\LOADLIB>  ezSCHEDULE SIMOBATA CUGENRJ1

Backup the KSDS to a Sequential File

It would be a simple task to recreate a New Customer Master File. However, we have chosen to make a backup copy as a record sequential file. This will serve two purposes in the future. First, it will provide an easy way to move the test data to an SQL data base. Secondly, the backup copy will be a reference point after the testing cycle is complete. We can use it to compare with the Customer Master to identify changes and validate correct or expected results. The following is the command that will submit the job that will add make a backup of the Customer Master File.

Reset the Log File

When doing Data File Compares and a difference is encountered the comparison program writes the information to a log file. This log file is accumulative and new information is continually added to the end of the log file. The following will reset the log file by doing a delete of the log file and a create of a new, empty log file.

Company Overview

SimoTime Technologies was founded in 1987 and is a privately owned company. We specialize in the creation and deployment of business applications using new or existing technologies and services. We have a team of individuals that understand the broad range of technologies being used in today's environments. Our customers include small businesses using Internet technologies to corporations using very large mainframe systems.

Quite often, to reach larger markets or provide a higher level of service to existing customers it requires the newer Internet technologies to work in a complementary manner with existing corporate mainframe systems. We specialize in preparing applications and the associated data that are currently residing on a single platform to be distributed across a variety of platforms.

Preparing the application programs will require the transfer of source members that will be compiled and deployed on the target platform. The data will need to be transferred between the systems and may need to be converted and validated at various stages within the process. SimoTime has the technology, services and experience to assist in the application and data management tasks involved with doing business in a multi-system environment.

Whether you want to use the Internet to expand into new market segments or as a delivery vehicle for existing business functions simply give us a call or check the web site at http://www.simotime.com
