TmaxSoft's OpenFrame is an all-encompassing solution for modernizing and replatforming mainframes, allowing organizations to transition their outdated mainframe applications and data to contemporary systems like Linux, Unix, Docker containers, or public cloud infrastructures without altering existing business logic, thereby maintaining core functions, cutting down on total ownership costs, and steering clear of perilous rewrites. This innovative solution features a forward-thinking, standard three-tier architecture that enhances performance, stability, flexibility, and scalability in comparison to conventional mainframes, accommodating over 100K MIPS and boosting processing capabilities. OpenFrame leverages sophisticated compiler technology along with an integrated asset analysis tool known as OF Manager to seamlessly convert user interface logic, application logic, and data structures, enabling applications to function natively in open environments with minimal manual intervention. This capability ensures that current staff and skill sets can be preserved, leading to a smoother transition and continued operational efficiency. As organizations seek to adapt to evolving technological landscapes, OpenFrame provides a strategic pathway for modernization.

Oracle Forms Code Analyzer Tool: Customized Oracle Forms/Reports applications bring high levels of flexibility, but after years of code maintenance or modifications, your documentation of application code is outdated 90% of the time. ORMIT-Analyzer, a state-of-the art tool validated by Oracle, helps to understand existing development patterns and find opportunities to simplify source code. The goal is to get detailed information about the challenges and opportunities to enable a "future-ready software architecture" by separating the architectural components of software: User-Interface Business Logic, and Database. ORMIT-Analyzer can also be used to prepare a possible application modernization project, with the goal of protecting the investment made in the existing business logic while achieving a more maintainable and modern software architecture.
