Data Management Series
Non-Relational Data Management
|The SimoTime Home Page|
The primary purpose of this document is to provide a consolidated resource of information about application migrations between Mainframe systems and Windows or UNIX systems supported by Micro Focus technologies. The concepts available may be used regardless of the direction of the migration. A subset of moving or migrating an application is the data file management involved when moving, sharing and possibly converting data files.
A special "Thank you" to Larry Simmons of Micro Focus for providing much of the information that is presented in this series of white papers and sample programs.
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.

This section provides examples and links to documents that describe the management of data sharing or application migration between an IBM Mainframe System and a Windows System using Micro Focus. The information provided will cover data file transfer, conversion and comparison of non-relation or traditional sequential files and VSAM, Keyed Sequential Data Sets (KSDS).
This is a link to a white paper that provides a quick overview of the data management tasks required to migrate or share data between a Mainframe system and a Windows or UNIX system.
This is a link to a white paper that provides a quick overview of the data file transfer options available when transferring or sharing data between a Mainframe system and a Windows or UNIX system.
This is a link to a white paper that provides a quick overview of the possible data file conversion options available when migrating or sharing data between a Mainframe system and a Windows or UNIX system.
The self-study session for data file conversion includes a discussion about file conversion with a focus on EBCDIC and ASCII content conversion. The session includes a hands-on exercise that does an actual conversion of a data file that includes packed and binary data. The exercise shows how to do file content conversion at the field level.
This is a link to a white paper that provides a quick overview of the possible data file comparison options available when testing an application or data that has been moved between a Mainframe system and a Windows or UNIX system.
The self-study session for comparing data files uses a generated COBOL program to compare two data files. The session includes a hands-on exercise that does an actual data file comparison.
This is a link to a white paper that provides a quick overview of the various Micro Focus File Formats provided for the Windows and UNIX environments and supported by Micro Focus.
This section provides examples and links to documents that describe the challenges and solutions of migrating or sharing data between systems of different architectures. The following link discusses some of the Possibilities and Considerations for Application Migration and Data Sharing.
This is a link to a white paper that provides a quick overview of the various File Formats and Conversion Techniques provided for the Windows and UNIX environments and supported by Micro Focus.
This is a link to a white paper with an example that provides a quick overview of the various File Content Conversion, ASCII and EBCDIC provided for the Windows and UNIX environments and supported by Micro Focus.
This link provides an example of the various conversion and comparison processes that move data from EBCDIC encoded environments to ASCII encoded environments and from a Mainframe format to a format that may be easily imported into an excel spreadsheet. This suite of sample programs and documentation may be downloaded for training and evaluation purposes.
Note: You must have a connection to the internet to download a software package.
This document will describe and demonstrate how to create HTML documentation for record structures (non-relational files and/or VSAM Data Sets) based on the definitions provided from a COBOL copy file. To run the jobs described in this document will require the SimoTime Enterprise License for SIMOLIBR01 or SIMOZAPS02. Also, Micro Focus Enterprise Server or Enterprise Developer is required.
Explore how to create multiple HTML documents for record structures based on the definitions provided from the COBOL copy files. This includes record layouts for non-relational files and/or VSAM Data Sets.
This link provides an example of managing a File Properties Repository. This capability and the information it provides is quite useful when supporting applications or migrating an application (source code, control information and data) from a Mainframe System to a Linux, UNIX or Windows System using Micro Focus technologies. This suite of sample programs and documentation may be downloaded for training and evaluation purposes.
Note: You must have a connection to the internet to download a software package.

Migrating an application between systems of similar architecture (i.e. upgrade to existing mainframe) can be a challenging task. Migrating an application from a Mainframe, EBCDIC encoded system to a Wintel, ASCII encoded system requires an even higher level of planning and attention to detail.
With careful planning and a documented process the application migration process can move forward to a successful conclusion. 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 Services has experience in moving or sharing data or application processing across a variety of systems. For additional information about SIMOTIME Services or Technologies please contact us using the information in the Contact, Comment or Feedback section of this document.

We appreciate hearing from you.
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
