Program Control Table Extract PCT Entries from DFHDRDAT

Introduction

The resources used by the Micro Focus Enterprise Server, Mainframe Subsystem Support (or ES/MSS) are stored in the resource definitions file (DFHDRDAT). This file is a Micro Focus Key-Sequenced-Data-Set. This utility program provides a batch access to get the Program Control Table (PCT) and post this information into an ASCII/Text file.

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.

Programming Objectives

This example illustrates the following functions.

Programming Input and Output

Getting information from the PCT to a CSV file is a three step process within a single Windows Command File. The 1st Step does the preparation work by setting the environment and deleting any work files left by a previous execution.

The 2nd step uses the Micro Focus supplied utility program to extract information from the DFHDRDAT file and place it into an ASCII/Text file in a standard format that may be used to import the information into another CICS System. The following shows the command line syntax for the Micro Focus utility program. The value of %RDTFILE2% is the location and name of the output file.

 c:\> casrdtex /o%RDTFILE2% /gSIMOGRPA /x /e /ip"c:\SimoSam1\sysliba1".

The following shows an example of the output for a single PCT entry produced by the Micro Focus utility program.

DEFINE TRANSACTION(OPT1) GROUP(SIMOGRPA)
DESCRIPTION(Menu Transaction for File Management)
       PROGRAM(MN1FMS) TWASIZE(0) STATUS(ENABLED) DYNAMIC(NO)
       PRIORITY(0) DTIMOUT(65534) INDOUBT(BACKOUT) DUMP(NO) TRACE(YES)
       RESSEC(NO) CMDSEC(NO) TRANSEC(01) _SCREEN(ALTERNATE)
       _UCTRAN(YES) _INBOUNDTP(NO)

The 3rd step uses a SimoTime utility program that reads the output of the 2nd step and writes the information to a CSV file that may be easily imported into an Excel spread sheet. The following shows an example of the output produced by the 3rd step.

Programming Requirements

This suite of samples programs will run on the following platforms.

Programming Overview

The following is a flowchart of the job for executing the programs that will extract PCT information from the Micro Focus online configuration file (DFHDRDAT).

Step 4 of the preceding flow chart uses the Micro Focus supplied utility program (CASRDTEX) to extract the PCT information from the resource definition file. This information is then processed in step 5 by a utility program that places PCT information into an ASCII/Text file with CSV formatted records. This file may be viewed with a standard text editor or easily imported into an Excel spreadsheet.

CMD for Batch Execution

The following (CSDPCTE1.cmd) is a sample of the Windows CMD needed to run this job.

This is a Work-In-Progress, contact SimoTime for additional information.

Summary

This utility program provides a batch access to get the PCT information in the Micro Focus Resource Definition File (DFHDRDAT) and post the information into an ASCII/Text file. The document may be used to assist as a tutorial for new programmers or as a quick reference for experienced programmers.

In the world of programming there are many ways to solve a problem. This documentation and software were developed and tested on systems that are configured for a SIMOTIME environment based on the hardware, operating systems, user requirements and security requirements. Therefore, adjustments may be needed to execute the jobs and programs when transferred to a system of a different architecture or configuration.

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.
