Mainframe Rehosting with Oracle Tuxedo: Accelerating Cost Reduction and Application Modernization

Migrating an MVS Mainframe Application to a PC

Due to advances in computer architecture, performance of the PC now exceeds that of the typical mainframe. However, computing cost on a mainframe continues to greatly exceed that on a PC. Thus, migrating mainframe applications to PC can result in substantial savings. The major stumbling block in doing this is the cost of software migration itself. This paper discusses an experiment in using a s...

Modernization Secrets of the Fortune 1000: Mainframe Mips Reduction inside the Options and Optimal Solutions for Reducing Mips

A Perspective on Mainframe Re-hosting

Mainframes form the backbone of many core business processes in organizations worldwide. However, the total cost of ownership, platform flexibility, and administration and programming skills associated with them have been critical areas of concern in recent times. Banking solely on unsupported legacy systems might not just create reliability and performance issues, it could also lead to more re...

Portability of STDL on Top of the TUXEDO Transaction Monitor

The Structured Transaction Definition Language (STDL) is a language based programming interface to transactional protocols and runtime systems, designed to resolve the industry problem of incompatible Transaction Processing (TP) monitor programming interfaces. STDL defines a three-group model, in which application procedures are grouped according to the type of work they perform: presentation, ...

Modernization of Legacy Application Software

Legacy application software is typically written in a dialect of Fortran, and must be reprogrammed to run on today's microprocessor-based multicomputer architectures. We describe our experiences in modernizing a legacy direct numerical simulation (DNS) code with the KeLP software infrastructure. The resultant code runs on the IBM SP2 with higher numerical resolutions than possible with the lega...
