Libraries for Development
Structure for an Enterprise System
|The SimoTime Home Page|
The Application Libraries (directories and sub-directories) are structures that provide a Mainframe System Model for analyst, technical administrators, testing groups and support individuals to store configuration files, programs and job scripts that support an application infra-structure. This document will focus on a directory structure for the development environment.
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.

The following diagram shows the model sub-directory structure for the Application Libraries and the DEVELOPMENT environment. The Application Libraries are typically a sub-directory under a directory structure for a Development, Production or Test environments. Update or change capability to the Application Library structure and content may be limited to system and support individuals. Read or view access typically has a larger audience.

This section provides additional detail about the Application Libraries and some of the system and support functions available. This description will use the SimoTime Application samples that use a base directory of SIMOSAM1. The additional directories will be sub-directories under this base directory.
The SIMOSAM1\DEVL directory structure is intended to be used by programs and other individuals the support the application creation, testing and ongoing support processes.
This directory contains commands and data that provide technical administrative function. Administrative functions include the following.
|A List of Administrative Functions|
This link provides additional information about the sub-directory structure for Technical Administrative Tasks that includes the processes for the scripted builds and the management of the Repository of Application Properties.
This directory contains the source code for the Assembler (Mainframe HLASM) source members. The source members typically have an extension of filename.MLC.
This directory contains the source code for the BMS source members. The source members typically have an extension of filename.BMS.
This directory contains the COBOL Copy File (or copybooks) used by the application programs. The source members typically have an extension of filename.CPY.
This directory is reserved for use by the BMS Generation process. It contains the copy files that are generated by the BMS Generation process. The source members typically have an extension of filename.CPY.
This directory contains COBOL Source Code for application programs that deliver business function. The source members typically have an extension of filename.CBL.
This directory contains COBOL Source Code for programs that perform utilitarian function in support of the application but are not part of the application that delivers business function. The programs in this directory should be compiled using a mainframe dialect. The source members typically have an extension of filename.CBL.
This directory contains COBOL Source Code for programs that perform utilitarian function in support of the application but are not part of the application that delivers business function. The programs in this directory should be compiled using a Micro Focus dialect. This suite of programs uses functions and syntax that is unique to the Micro Focus compiler. The source members typically have an extension of filename.CBL.
This directory contains COBOL Source Code for programs that perform utilitarian function in support of the application but are not part of the application that delivers business function. The programs in this directory have unique or specialized function and require specific compiler directives. The source members typically have an extension of filename.CBL.
This directory and its sub-directories contain non-relational data files that are accessed by the application programs and programs that support the infra-structure for the applications.
This link provides additional information about the sub-directory structure for non-relational Data that includes files that are used by Micro Focus Enterprise Server, the application programs and the utility programs that support the applications.
This directory contains the filename.DIR files that are use when compiling the various categories of COBOL Programs. The following shows the different categories.
|Categories of Programs and Associated Directives Files for Scripted Builds|
Explore A Scripted Build for additional information about how to do an automated, unattended build of an application that was migrated from a Mainframe System.
This directory contains documents that are used by individuals that are involved with the development, test and execution of the application programs and processes.
This sub-directory is a holding place for load members to be promoted to the Quality Acceptance Testing environment.
This directory contains the HTML documents for the systems and application environments.
Explore The Enterprise System Model for additional information about defining, creating and managing the Environments, Processes, Functions and Data that are needed (required) to expand the platform flexibility and allow a business application currently running on a mainframe system to run on a Windows, UNIX or Linux system using Micro Focus Server Enterprise Edition.
This directory contains the IMS Members. The execution-time members are in this directory. The source code is in two sub-directories, DBD and PSB.
This directory contains Java Source Code for application programs. The source members typically have an extension of filename.java, filename.jsp or filename.htm.
This directory contains the JCL Members that are submitted to and executed by the Micro Focus Server. The JCL Members (Job Control Language) are used to define a batch job consisting of a single job step or multiple job steps. The mapping of the physical file names to the Data Set Name (DSN) and DD name (file name used by program) is done within the JCL Member.
This directory contains JCL INCLUDE members. The content of an include member is used to replace an INCLUDE statement in the Primary JCL member. The included JCL statements are then processed with the submitted JCL stream of statements.
This directory contains the load members for this suite of sample programs. The types of load members are GNT's, MOD's and CMD members.
This directory is reserved for the LOG files produced by the applications and/or system utility programs used with this suite of application programs.
This directory contains the control file (sometimes referred to as control cards) for the programs used by the applications. An example would be a control file that contains the sort specifications used by the Micro Focus SORT program.
This directory contains the JCL Procedures (or PROC's) used by the JCL for the batch jobs of the application being migrated.
This directory contains the REXX program members that are executed by the IRXJCL program in a Micro Focus batch environment.
This directory contains a set of sub-directories. The sub-directories contain the members that are used to generate programs that will do data conversion, data validation and data review.
This directory is reserved for use by the systems and support teams. It contains programs that are used in support of the application, system and sub-system environments and are not part of the application programs that deliver business functionality. Access to this directory is usually limited to system and support personnel.
This document will focus on a directory structure for the development environment. This 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.

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
