Table of Contents Previous Section Next Section Introduction

This purpose of this document is to serve as a repository for links to other SimoTime documents and examples that describe or show many of the details involved with Application Migration or the moving of an application between platforms such as a Mainframe System running ZOS and a Linux, UNIX or Windows System running Micro Focus Enterprise Server. Since most mainframe applications are COBOL-oriented this document has a bias toward moving these applications with minimum changes. To do this the examples use Micro Focus Enterprise Developer for the Linux, UNIX or Windows environments and standard COBOL/390 or later for the Mainframe environments. Many of the examples will run in a COBOL/2 environment. Programs that contain code that needs to be Y2K compliant will require COBOL/390 or later.

This document has a special focus on data file transfers between systems. Links are also provided to documents and examples that describe or show techniques for doing file format and record content conversion. Reading an indexed file and creating a sequential file would be an example of file format conversion. Reading an EBCDIC-encoded file and writing an ASCII-encoded file would be an example of record content conversion.

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.

Additional programs are included for converting ASCII, Text files to Indexed files. The examples also show how to manage Packed-Decimal and BINARY or COMP fields.

Link to Internet   Link to Server   Explore the cycle of converting and transferring non-relational data files between an IBM Mainframe System and a Windows, Linux or UNIX System. This discussion will leverage the non-relational file support provided by Micro Focus for the distributed systems.

Table of Contents Previous Section Next Section A Linux Project

This link provides access to the notes created by a development team that was transferring programs and data from an IBM Mainframe System to a Linux System. The team was familiar with the Mainframe and Windows but needed to develop the Linux skills.

Link to Internet   Link to Server   Explore a Project that will re-deploy a Mainframe Application to a Linux Platform. The goal is to deploy a segment of a business application that is currently running on an IBM Mainframe System onto a Linux System. The business application is a suite of batch jobs running in an EBCDIC-encoded environment. The current batch jobs are scripted and executed using Mainframe JCL (or Job Control Language). The application programs are written in COBOL and compiled using IBM Enterprise COBOL. The user data is stored in EBCDIC-encoded, non-relational data structures. The Linux System will be an ASCII-encoded environment and the batch jobs will be scripted and executed using Bash Shell Scripts. The COBOL programs will be compiled using GnuCOBOL. The user data will be stored in ASCII-encoded, non-relational data structures.

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.

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
