Abstract

Para atender o objetivo de desativar o Mainframe da CSN tornava-se necessário migrar todas as aplicações desenvolvidas neste ambiente para outra plataforma. Assim iniciou-se o projeto que foi denominado “Renova”, um projeto que teve a duração de três anos e que transferiu para uma plataforma mais moderna e com custo de manutenção menor, os diversos sistemas que eram processados no mainframe. O projeto foi considerado de alta complexidade pois envolveu sistemas de informação de todas as áreas da empresa, desde o setores administrativos, comerciais e logísticos até a área de produção. Para cada sistema foi adotado uma solução específica onde foram analisadas diversas tecnologias do mercado. O trabalho de migração com conseqüente desativação do mainframe foi executado nas seguintes etapas: Inventário e mapeamento dos sistemas do mainframe, análise financeira do projeto, definição da solução para cada um dos sistemas, formalização das soluções junto às diversas áreas usuárias, implementação das diversas soluções, migração de dados históricos e desligamento definitivo do mainframe.

 

In order to achieve the purpose of shutting down the CSN Mainframe, it was necessary to migrate to a different platform, all application which had been previously developed for the mainframe environment. That was the start of a project named “Renova”. The Renova project lasted for three years and took care of transferring to a more modern and cost effective in terms of maintenance, all of the numerous systems that were processed at the mainframe. This project was deemed to be of a high level of complexity, once it comprehended information systems from all over the company’s division, from the administrative to the commercial and logistic ones, as well as the production area. It was applied a given solution for each system, process in which the variety technologies made available to the market were taken into account. The migration process and its consequent mainframe shutting down were accomplished as per the following steps: Mainframe systems inventory and mapping, Project finance analysis, Establishment of a solution for each one of the systems, Officialize the solutions towards the several user areas, Implementation of a variety of solutions, Migration of historical data and finally Mainframe shutting down.
