Prepare & Configure System, Application and Data Options |
The SimoTime Home Page |
When migrating an application from a mainframe it is necessary to create a new system (consisting of Hardware, Operating System Software, sub-System Software and System Utility Programs) to receive the application and its associated data.
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.

One of the first tasks to complete is to define where to put everything in the new system environment. The Best Practices approach will typically manage the application assets in a development environment and then promote load members and associated components to a Test environment with the final promote to the Production.
This document and the Proof-Of-Concept focuses on the development environment.
Additional detail about a Directory Structure for the Development Environment is available in a separate document.

Additional information about the Server Configuration for Baseline and Batch is available in a separate document. This document contains a description of how to populate the catalog with the necessary Partitioned Data Sets (PDS's).

The following shows the content of the MFENTMAP.dat configuration file that defines an entry point into a COBOL program. The entry point is then available for dynamic binding (or linking) at execution time. The MFENTMAP.dat file is a Line Sequential (or ASCII/Text) file.
[ENTRY-POINT] GENATMSP [PROGRAM-NAME] * [SUBPROGRAM-NAME] ZCTMSP
The location of the MFENTMAP.dat file is defined by using the ENTRYNAMEMAP environment variable. The following is an example.
set ENTRYNAMEMAP=%BASESYS%\CONFIG\
Once an entry point is defined it is necessary to enable the function
The following shows the content of the DIAGNOSE.cfg configuration file that may be used to enable or disable various functions available within Enterprise Server at execution time.
set entry_point_mapper=TRUE set CORE_ON_ERROR=131 set CORE_FILENAME="core.%p@%t_%d"
The location of the DIAGNOSE.cfg file is defined by using the COBCONFIG_ environment variable. The following is an example.
set COBCONFIG_=$ESROOT\ES\cfg\Diagnose.CFG
Note: For the Linux environment the COBCONFIG_ is COBCONFIG without the trailing underscore.
The following shows the content of the configuration file for the Consolidated Trace Facility (CTF).

When migrating an application from a mainframe it is necessary to create a new system (consisting of Hardware, Operating System Software, sub-System Software and System Utility Programs) to receive the application and its associated data. This document may be used 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 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.
