Trenton Computer Festival Professional Conference features Architectural Techniques for Interoperability and Coexistence

Software architectures enable systems to have long productive lives and eliminate the need for expensive, on-going revisions. Good architecture also enables systems to evolve to additional tasks and missions without incompatible changes. Systems can operate efficiently for decades, with low costs while assimilating dramatic changes in underlying technologies.

Long Island Systems, Applications, and Technology 2007 (LISAT 2007) features Safe Computing in the Age of Ubiquitous Connectivity

This presentation will examine the challenge of today’s “office”, which is anywhere one happens to be: cubicle, conference room, customer site, coffee shop, or park. Broadband connections, both wired and wireless, enable this agility, and expose information systems to new challenges and responsibilities. Maintaining the integrity and confidentiality of information systems is a vital, ongoing, challenge.

The official conference proceedings contain a seven page paper by Mr. Gezelter analyzing the challenges and possible solutions; with recommendations that enhance privacy and security while simultaneously enabling access by insiders and guests alike.

A complete abstract of this talk, the slides, and a re-print of the conference paper can be found on our www site at:

Hewlett Packard 2007 Technology Forum features speech on Migrating OpenVMS Storage Environments without Interruption/Disruption

With the ever increasing requirements for uptime and availability, downtime for reconfiguration and replacement of storage has become increasingly rare. The need for maintenance and re-structuring has increased, but full time online availability leaves no convenient time for offline maintenance.

This presentation will illustrate how standard OpenVMS facilities can be leveraged to enable significant changes to storage configurations, without interrupting normal use.

Others are challenged by one or more of these conditions. The obstacle may be technical, in terms of old or missing sources, inter-relations between components, or lack of staff time to make volumes of small changes. Business issues, including leases on existing systems, operational commitments, and business initiatives, also present obstacles. All of these can induce difficulties in what should be an otherwise straightforward process.

This whitepaper will explore strategies for leveraging unique OpenVMS features to achieve low-risk, low-effort transitions to the Integrity platform while transparently maintaining commitments to the enterprise. These OpenVMS facilities, including the Alpha Image Translator, the Translated Image Environment, logical names, mixed-architecture OpenVMS clusters, and Host-based volume shadowing enable us to allow a transition from Alpha and VAX to HP Integrity on an incremental basis, reducing risk and increasing flexibility.
