Create a Batch Job Server Enterprise Server, a JES sub-System

Introduction

The purpose of this document is to describe how to configure a JES sub-system (or Batch Server Instance) that will run under Micro Focus Enterprise Server. To run all the examples in the SimoTime suite of programs it will be necessary to populate the catalog with a minimum number of Partitioned Data Sets (or PDS's).

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.

Configure a JES Sub-System

This section provides the information needed to configure a JES Sub-System (or Batch Server Instance) running under control of Micro Focus Enterprise Server.

Basic Options for Batch Configuration

The server used by the batch applications will be called SIMOBATA. At the bottom of the home page for Enterprise Server Administration select the "ADD" button. The following describes the primary configuration options needed to submit, execute and review jobs that have been defined (or scripted) using the Job Control Language (JCL Members and Procedures).

Enter a Server Name, select the Working Mode and Click the" Next" button. Click the Radio button for Micro Focus Enterprise Server with Mainframe Subsystem Support and Click the" Next" button a second time.

The following shows the next group of configuration options. For items not shown take the default entry options.

Note: For the following and if not required then un-check the TN3270 and ISC listener boxes

Click the" Add" button.

The "SIMOBATA" server should be added to the Enterprise Server. When the home screen is redisplay click on the "Edit" button, select the "MSS" tab, select the "JES" tab and then enter the following configuration options for the JES or Job Entry Subsystem.

Note: For the following remember to check the box for the "Job Entry Sub-system enabled".

Job Entry Subsystem enabled:    JES Program Path: $BASEAPP\LOADLIB;$BASEAPP\SYS1\LOADLIB;C:\SimoLIBR System Catalog: $BASECAT\CATALOG.DAT Default Allocated Dataset Location: $BASECAT\APPL System Procedure Library: SIMOTIME.PDS.JCLINC;SIMOTIME.PDS.PROCLIB1    Apply

Click the "Apply" button.

Note: Some environment variables are set prior to starting the server. This needs to be done since some environment variables will be used by ES/MSS and other third-party technologies. The decision was made to define the shared environment variables in one place rather than replicate in the two separate environments.

The next step in the configuration of the JES sub-system is to define the JES initiators and have them start automatically when the JES Server (or sub-system) is started. To do this select the "Initiators" tab then click the "Add" button to add an initiator. The following should be displayed.

Fill in the required information and click the "Add" button.

Configure Batch Job Initiators

The next step in the configuration of the JES sub-system is to define the JOB initiators and have them start automatically when the JES Server (or sub-system) is started. Multiple Job Initiators may be defined.

To do this select the "Initiators" tab then click the "Add" button to add an initiator. The following should be displayed.

Fill in the required information and click the "Add" button.

Note:  Multiple Job Initiators may be defined and a batch Server Execution Process (SEP) will be created for each Job Initiator.

Start the JES Server

The starting and stopping of a server that provides application support to a number of business users is a task that is usually reserved for operations or systems personnel or it is a scheduled task. Micro Focus provides the commands to start or stop a server and these commands may be explicitly called and executed. This can be very useful in the unit test environment but it is not a practical solution for a larger, multi-system, multi-user environment. Therefore, the model mainframe example provides a Windows command file that sets various environment variables and starts the JES Server.

The SYS1START command file calls the ENV1BASE command file to set commonly used environment variables. It then calls the SYS1BAKConsole command file to provide a backup of the previously created "console.log" file. It then starts the specified server based on the first parameter of the command line. The following is an example of the command line syntax.

C:\SIMOSAM1\SYS1\LOADLIB> SYS1START SIMOBATA

This link provides additional detail about the  Pre-Defined System and Application Commands  that include the "SYS1" and "EZ" Series suite of commands.

Create Catalog Entries for PDS's

Some of the jobs included in the SimoTime suite of samples use Procedures (PROCs) and INCLUDE statements. Some of the jobs reference parameter files. These are stored in directories on the LUW platforms. These directories need to be mapped to a PDS with an associated catalog entry. If the number of PDS's used by an application is small it may be easier to manually create the catalog entries using the browser interface of the Micro Focus Enterprise Server.

If an automated and repeatable process is required or manually creating catalog entries for a large number of PDS's would be very time consuming then a programmatic approach may be a better solution.

This link provides detailed information to Identify, Document and Create Catalog Entries for Partioned Data Sets (PDS's).  This approach uses a list of PDS Members that are managed in an Excel Spreadsheet and saved as a Comma-Separated-Values (CSV) file. This provides for a documented, repeatable process.

Submit & Execute, Validation Jobs

A suite of "User Validation" test jobs is provided and may be used as a test to confirm the JES Server is configured, the catalog entries for the PDS's are correct and the JES Server is started and ready to accept jobs.

This link provides detailed information to the  User Verification Tests for the JES Server  . This suite of test jobs starts with a simple test of the basic functions and advances step-by-step through the advanced functions.

Summary

The purpose of this document is to describe how to configure a JES sub-system (or Batch Server Instance) that will run under Micro Focus Enterprise Server. This document may be used to assist as a tutorial for new programmers or as a quick reference for experienced programmers.

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.
