Prior to expanding and expounding on legacy integration issues, it is important to understand precisely what is meant by that most misused of words, “legacy.” All too often it is used to denote something past its prime or of no use. This might be the case in certain instances but is by no means the case in all situations. However, there is one aspect of legacy that does bear closer inspection; one that cuts to the heart of integration (and other aspects of legacy use). It boils down to one key word: understanding. Without understanding, there can be no definition of legacy that is useful and legacy that is not…

Today, IT must keep pace with demands for new applications and capabilities. This is in addition to new mandates for governance and accountability and the growing need to rationalize increasingly diverse sets of applications and data. Within this context, legacy systems integration presents a host of issues likely to be familiar to any CIO—growing project backlogs and expanding system complexity as code changes cascade through myriad applications and data structures. Compounding this is a mandate to do more with less—deliver greater functionality and manageability in the face of declining IT budgets…

One task that both business and IT managers face today is integrating business processes and legacy systems. They view integration somewhat differently, based on their separate roles, but their common goal is to improve the way people and systems inside and outside their enterprises work together in support of business strategies. As the premier provider of mainframe hardware and software, as well as a powerhouse in integration, IBM’s approach to legacy integration will undoubtedly affect everyone involved…

Legacy transformation—the automatic transformation of legacy languages, such as COBOL or PL/I, to modern languages, such as Java—is dying. These big-bang transformation projects are losing their appeal because the business model is flawed. Source code translation is an imperfect and complete system replacement process. Third-Generation Language (3GL) structure doesn’t translate well into Object-Oriented (OO) constructs, and language transformation ignores the substantial environmental changes necessary for success…

This article explains several high-impact z/OS ISPF settings that you can change at the individual user level. We’ll focus on settings that apply globally (sessionwide) at the individual user level. Every ISPF user on a z/OS machine can have different values for the settings we’ll cover. Once these settings are established, they apply to many aspects of an individual ISPF session on all screens…

What, exactly, does “legacy integration” mean? Most old hands in IT would certainly agree that integrating a non-mainframe application with a mainframe application would qualify. Of course, our interpretation of legacy integration has evolved over the years. We now include the integration of almost any applications, as long as the architecture of one of the applications is significantly older. Any application that was not designed to support the distributed architecture du jour, let alone the many standards de facto and de jure, is now said to be a legacy application…

Service-Oriented Architectures (SOAs) allow enterprises to share common application services and information. This sharing is accomplished either by defining application services that can be shared and therefore integrated, or by providing the infrastructure for such application service sharing. Application services can be shared by hosting them on a central server or by accessing them inter-application (e.g., through Web Services)…

Acursory scan of the headlines in IT trade press publications this month presents a pretty grim picture. In numerous state governments, CIOs have resigned or been fired amidst claims of rampant IT mismanagement, while the Government Accounting Office reports that more than $2 billion in IT funding has been wasted at the Department of Defense…
