The collapse of the bridge in Minneapolis over the Mississippi River in 2007 is just another reminder that our infrastructure is aging. Many of our bridges, water pipes, and roads have been in service far longer than their design called for. In a similar way, our computer infrastructure often consists of code created 20 or more years ago. While code doesn’t deteriorate in the same way physical structures do, it does shows its age in other ways. Code designed many years ago will need to be replaced with more modern code that reflects current capabilities and meets the requirements of today’s business…

A Primer: DFSORT’s Powerful New Functions

In July 2008, IBM introduced PTF UK90013, providing new capabilities for DFSORT and its ICETOOL utility. Now you can do find-replace and group operations while you’re sorting, copying, or merging. You also can benefit from changes to ICETOOL’s existing COUNT, DISPLAY, OCCUR, SELECT and SPLICE operators and the use of two new operators (DATASORT and SUBSET).

Mainframe Hall of Fame

Something I have long wanted to do was to create a Mainframe Hall of Fame. Periodically, in this blog I will honor key individuals who have been instrumental to the long-term success of the IBM mainframe. So naturally the first inductee needs to be Thomas J. Watson, Jr.

Mainframe systems hold the IT power that drives the largest enterprises, yet their tremendous potential often remains locked up in siloed systems. CIOs and IT executives realize the need for agility and reuse in today’s environment. They must satisfy new regulatory and business requirements for reporting, security, privacy, straight-through processing, and Business-to-Business (B2B) integration. Yet there’s neither time nor need to redevelop core functionality now supported by mainframes. Instead, executives have been undertaking Service-Oriented Architecture (SOA) projects to expose their mainframe functionality as services: simple, loosely coupled interfaces that reflect business needs…
