Introduction

Creating and maintaining an inventory of data files can be a challenge. The challenge is not with the degree of difficulty or complexity. The challenge is with the realization of the value, a commitment to the task and elevating the priority of doing a very boring task. However, once it is accomplished it becomes a very worthwhile repository of information that can be used in the planning, development, testing and production environments.

Information about the characteristic (or properties) of a Data File, Data Structure (such as a PDS or GDG) or VSAM Data Set is not always readily available. In today's world when application processing is being moved between systems and data is being transferred, shared, converted and compared an inventory of data files can be quite helpful.

This example will use a Windows System running Micro Focus Enterprise Studio to create a Key-Sequenced-Data-Set (or VSAM, KSDS) containing an inventory of Partitioned Data Sets, Generation Data Groups, Sequential Files and VSAM Data Sets. Once the inventory of data sets has been created it will be possible to use this information to build a catalog for Micro Focus Mainframe Express or Micro Focus Studio/Server environments.

Note: This document is currently a Work in Progress

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.

Gather non-Relational Data Info

There are numerous ways to gather information about the existence of files and the file properties. This section will discuss various methods for collecting information about files used by an application.

1	Create a Spreadsheet for the Inventory of the Partitioned Data Sets (PDS's)
2	Create a Spreadsheet for the Inventory of the Generation Data Groups (GDG's)
3	Create a Spreadsheet for the Inventory of the Sequential Files
4	Create a Spreadsheet for the Inventory of the VSAM Data Sets

Build Four Excel Spreadsheets for the Data Set Inventory and Associated Properties

Spread Sheet Information

The following is the column structure for an Excel spreadsheet to be used as a starting point to populate the catalog.

* HTMGE

Column - Label

Description

A - Level Number

This should be a "1" for the primary file definition information. A zero (0) is used to define the row that is used for column headers.

This is a text string with a maximum length of forty-four (44) characters. It is the fully-qualified MVS Data Set Name (DSN) or VSAM Cluster Name

C - DD Name

This is a text string with a maximum length of eight (8) characters. It is the DD Name.

D - DSORG

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
