OpenVMS Technical Journal - V10 June 2007

Welcome to the June 2007 of the OpenVMS Technical Journal. As always we have a number of excellent articles for your reading pleasure. In this issue you will find a wide variety of articles ranging from Strategies for migrating from Alpha and VAX Systems to HP Integrity Server Systems on OpenVMS to the dispelling of myths around Java in the Java and OpenVMS: Myths and realities article. Ted Saul has written and excellent article on OpenVMS: Striving to provide the support you need which I am sure you will enjoy. We have another web article Implementation of a web application maintenance and testing environment which will be very useful. We also have a continuing segment in the T4 space with another article titled Taking T4 to the Next Level. And last but certainly not least is an article by Bruce Claremont on Simplification thru Symbols.

The OpenVMS Technical journal is a volunteer effort by the authors and a team within HP without them this would not be possible, they continuously go above and beyond the call of duty.

We would appreciate your feedback not only on this issue but the OpenVMS Technical Journal as a whole.

Stratagies for migrating from Alpha and VAX Systems to HP Integrity Server Systems on OpenVMS

Article Title: Stratagies for migrating from Alpha and VAX Systems to HP Integrity Server Systems on OpenVMS » HTML, » PDF

Article Abstract: The ideal method for migration to OpenVMS on the Intel® Itanium® architecture is to recompile, relink, and requalify. For many users, this strategy has been highly successful. Many applications, each comprised of hundreds of thousands of lines of source code, have been ported virtually overnight.

Other organizations face more challenging circumstances. Restricted budgets, operational commitments, dependencies on layered products, staff shortages, the sheer number of applications, and the size of the aggregate source bases make the "all at once" strategy infeasible.

OpenVMS provides unique capabilities that allow an organization to assimilate HP Integrity servers in a phased, structured, extremely low-risk approach. This strategy decouples the different phases to the maximum extent possible, permitting the assimilation process to proceed transparently to users, with minimal disruption to operations and minimal business risk.

OpenVMS has clustering and image translation capabilities that offer end-user management and technical staff a unique degree of flexibility. In the past, this flexibility has enabled OpenVMS to confound critics by enabling the assimilation of Alpha processors and, more recently, Intel Itanium processors. The same capabilities that enabled the rapid assimilation of radically different hardware architectures by the OpenVMS Engineering organization itself are fully available to independent software vendors and end users.

OpenVMS: Striving to provide the support you need

Article Title: OpenVMS: Striving to provide the support you need » HTML, » PDF

Article Abstract: The last year has seen significant change in how Hewlett-Packard provides support for the OpenVMS customer. Some of the change has been viewed negatively while other aspects in a positive manner. Throughout the change there has been on-going work to provide customers with the best possible support while remaining consistent with HP's long-term goals. This article seeks to describe how OpenVMS support is currently structured and what steps are being taken to ensure success for both the customer and HP. It seeks to provide understanding to those not familiar with all the work that goes on behind the scenes to ensure the customer problems are solved in a timely and efficient manner. The OpenVMS Global Competency Center will provide the ma in case study in demonstrating how one team has grown globally and has been able to partner with its resources around the world to provide seamless support.

Author Bio: Ted Saul, OpenVMS Offsite Consultant and Global Project Manager
Ted Saul has been a support consultant with Digital/Compaq/HP for over 18 years. His primary role has been to provide support for the OpenVMS customer base. But also as important he spends his time managing various projects that affect the support strategy of OpenVMS. Working directly with customers and understanding their needs provide an advantage when working these types of projects and helps to provide customer centric solutions. Most recently his responsibilities have extended into the global model including working with teams from all regions.

Java and OpenVMS: Myths and realities

Article Title: Java and OpenVMS: Myths and realities » HTML, » PDF

Article Abstract: This article discusses certain myths regarding the use of Java™ programs in the OpenVMS environment. We have identified three myths that, although dispelled by the facts, remain prominent within the OpenVMS and Java communities:

  • Java is slow.
  • Java is poorly adapted to OpenVMS.
  • Java is totally portable.

Implementation of a web application maintenance and testing environment

Article Title: Implementation of a web application maintenance and testing environment » HTML, » PDF

Article Abstract: The article is based on experience gained in the process of transition from one webserver to another, setting up multiple virtual servers using one webserver, and setting up a system with different webservers active concurrently, for testing purposes. It will mainly cover the differences found in the services, some hints on how to overcome them, or limitations found because of a different handling. It will show some data taken from configuration files, logs and screendumps.

It is NOT intended to give a qualification of each server involved.

Taking T4 to the Next Level

Article Title: Taking T4 to the Next Level » HTML, » PDF

Article Abstract: It is hard to believe that the T4 approach has now been around for almost seven years, and that year by year it has achieved wider acceptance while incrementally improving its underlying capabilities.  This is easily seen in the long list of enhancements added to the T4 collector, the large number of productivity changes for TLViz and CSVPNG, and the step-by-step increase in the number of T4 compatible collectors, now totaling more than 20.  We have seen time and again that the T4 approach encourages collaboration while doing performance work.

This article briefly looks back at T4's origins and where it has been, and then projects the likely trajectory it will take in the years to come as it builds even further improvements onto an already solid foundation.  This article also provides you with references to all the latest T4-related resources and to where you can turn for help and advice so that your OpenVMS performance work can achieve the maximum benefit from this approach.

Author Bio: Steve Lieman, Performance Architect, TrendsThatMatter
Steve Lieman has made hands-on practical use of T4 from its earliest beginnings. He actively employs T4, TLViz & CSVPNG as essential ingredients of his performance work for TrendsThatMatter. Steve's audio segments on T4 technical tips are a regular feature of the VMS Podcast Network (VPN) program and Steve wrote the first in-depth article on T4 that appeared in Volume 3 of the OpenVMS Technical Journal. The easy reader version of the article (just created recently) is a great way to begin learning about T4 and to get a sense for the visual nature and the power of this approach.

Steve was a member of the OpenVMS Engineering Performance Group for 11 years and he has more than 25 years of enterprise system performance management experience. Steve has been a regular speaker about T4 at every OpenVMS Boot Camp and at the popular OpenVMS Technical Updates in Europe and in the United States. He has delivered seminars and hands-on workshops on practical performance management at more than two dozen locations in the U.S, Canada, Europe, and the Pacific Rim. Steve also participated on the Transaction Processing Council in its formative years while it was developing and defining the TPC-C benchmark. You can learn more about Steve at TrendsThatMatter.com
