Yamagiwa is a company that specializes in interior design, promoting a novel lifestyle with an emphasis on the design and quality of products such as lighting fixtures, furniture, and home appliances.

Yamagiwa’s information system was developed based on a mainframe implemented over two decades ago. The mainframe had excellent processing ability and high reliability during operation. However, due to the high cost of maintenance and procuring hardware and software, it lacked flexibility and expandability when it was necessary to modify the system to meet changes to business requirements. To adapt to its new business model, Yamagiwa needed to adjust the size of its information system and integrate it to external systems. As a result, its information system underwent a drastic reformation.

Junichi Itabashi, the project manager of the management supporting division of Yamagiwa said, “Because our mainframe is a large-scale system, it is very difficult to add, organize, or combine functions. Furthermore, the ERP system we reviewed was totally unsuitable to our company.”

After reviewing its options, Yamagiwa decided to choose rehosting, which would migrate application assets from a mainframe to an open system platform. After comparing various commercially available solutions, Yamagiwa selected OpenFrame, a rehosting solution provided by TmaxSoft.

OpenFrame is a world-renowned rehosting solution with numerous customer references. With its powerful built-in enterprise-level TP monitor, Tmax, OpenFrame produces equal or higher performance and reliability results than that of a mainframe. Moreover, OpenFrame reduces errors and supports smooth migration by using tools and utilities that automates processes such as analysis, migration, and testing.

Yamagiwa’s information system was migrated to the Linux platform and started operations. Compared to its previous system, the response rate was improved by 20%, and the monthly system maintenance cost (including network cost) was reduced by approximately 30%.
