Table of Contents Previous Section Next Section Introduction

This document will describe how to create a list of the Generation Data Groups that are used by an application or group of applications. Once a list is created it will be used to programmatically create the entries in the Micro Focus catalog.

For this example we will use Microsoft Excel to create and maintain the list of names and properties for Generation Data Groups

Table of Contents Previous Section Next Section Format of the Excel Spreadsheet

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

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.
B - DSN 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 This is the Data Set Organization.
E - RECFM This is the Record Format.
F - lrecl-MIN This is a numeric string with a maximum length of five (5) digits. It is the minimum or average record length.
G - lrecl-MAX This is a numeric string with a maximum length of five (5) digits. It is the maximum record length.
H - KeyPos This is a numeric string with a maximum length of five (5) digits. It is the key starting position. The first position in a record is 1
I - KeyLen This is a numeric string with a maximum length of five (5) digits. It is for the length of the key.
J - VSAM Data Name This is a text string with a maximum length of forty-four (44) characters. It is the VSAM Data Name for KSDS and ESDS
K - VSAM Index Name This is a text string with a maximum length of forty-four (44) characters. It is the VSAM Index Name for KSDS
L - Override Job This is a text string with a maximum length of eight (8) characters. It is the JCL Member name that will be used to override the generated JCL that is used to create the catalog entry.
M - User Job 1 This is a text string with a maximum length of eight (8) characters. It is the JCL Member name for a job that will be submitted to the internal reader after the catalog creation process is complete.
N - User Job 2 This is a text string with a maximum length of eight (8) characters. It is the JCL Member name for a job that will be submitted to the internal reader after the previous steps are completed.
O - Extended S1 This is a text string with a maximum length of four (4) characters. The content varies.
If DSORG=PO then this field contains the extension of the PDSM that is used for a dynamic PDS.
P - Extended S2 This is a text string with a maximum length of four (4) characters. The content varies.
Q - Extended M1 This is a text string with a maximum length of sixteen (16) characters. The content varies, refer to Note-1
R - Extended M2 This is a text string with a maximum length of sixteen (16) characters. The content varies, refer to Note-1

V - Extended X2 This is a text string with a maximum length of 256 characters. The content varies.
If DSORG=PO then this field contains the path to the directory that contains the PDS Members.
Note-1: The Extended M1 trhough M4 fields are sixteen (16) byte fields. The content varies.
If DSORG=GDG the following values are accepted:
 LIMIT(nnn) where nnn is the number of active generations
 SCRATCH or NOSCRATCH, SCRATCH will physically delete the generation, NOSCRATCH will uncatalog the latest generation
 NOEMPTY or EMPTY, This specifies, what action is to be taken when the GDG becomes full base on the number in the LIMIT.

From within Excel save the GDG List of Names and Properties to a CSV file. Execute the command (CATGDGE1.cmd) to convert the Line Sequential file with comma values to a record Sequential file with fixed field lengths. Submit a job (CATGDGJ2.jcl) to the JES Server to create a catalog entry for the new file that contains a list of Generation Data Groups that need to be created.

The following shows the process flow of the CATGDGE2.CMD member.

Table of Contents Previous Section Next Section 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.
