In regards to the additional products, we have a skin installed and we have a product that we had custom developed for us that connects to a PostgreSQL database. We've looked at slow PostgreSQL queries causing problems and have not been able to find an issue. We've also tested for the case where the PostgreSQL server is down and have not been able to create an issue. We therefor...

Plone and Drupal are two leading open source Content Management Systems (CMS). Both were recognized in the 2009 Open Source CMS awards, run by Packt Publishing. Both also have large installed bases and large developer communities. This is made evident by some quick searching on Googl...
In 1998, a little-known company called VMware had just opened the doors of its Palo Alto office. Ever since computing moved from the mainframe to the desktop, the push had been bigger, faster, and more – more CPUs, more servers, more power, more cooling – and ultimately more complexity...
When it comes to defining Cloud Computing I typically take the stance of "I know it when I see it". Although I'm half joking, being able to spot an Internet centric platform or infrastructure is fairly self evident for the most part. But when it comes to an "OpenCloud API" things get a...
It’s no secret what’s driving the move to virtualization in data centers. The demand for new and expanded software systems is growing, but the geographic and carbon footprint required for scaling underutilized dedicated servers is too costly on many levels. This issue has led to the ma...
This article describes a method to use a perl debugger on trigger scripts without advanced interprocess debugging tools.
Using a perl debugger with a V4.x server side trigger launched by the server is very difficult and encounters two known obstacles:
The server will fire the tri...
Cloud computing is slowly gaining credibility and traction in the enterprise world. As giants such as Google and Amazon productize their massive cloud infrastructures, moving enterprise applications to the public cloud seems a more realistic possibility. The advantages of an enterprise...
In today’s economy, an enterprise must have strong financial motives for transitioning to SOA. SOA’s superior technical capabilities are a strong motive for information technology professionals to make that transition. However, enterprise stakeholders are motivated by solid investment ...
This article explains how an Open Source SOA Roadmap can use a typical Web application project’s funding as the basis for a successful SOA transition effort. It is the first of three articles that explains how open source technologies and techniques can be leveraged to successfully del...
I plan to make this the first of a series of articles that discuss the new features in PowerBuilder 11.5, which was released late last year. Of course, they won’t be the first articles we’ve run on the topic, as we ran an article on the new Code Access Security features back even befor...
“What would you think if I told you that you can develop a web application at least ten times faster with Rails than you can with a typical Java framework?” Oops! Ten times faster! Well, after these comments I decided to learn Ruby on Rails. I need to know the true key of the productiv...
A service inventory is a living body of services that individually will need the freedom to evolve independently over time. What we learned when documenting the SOA design pattern catalog is that there are patterns that emerged not only at design-time but also during this post-implemen...
Why developers want the software to be open sourced? I like quotes by great minds. Here's my favorite quote by Henry Ford: If you think you can do a thing or think you can't do a thing, you're right. Some of these chapters of our upcoming O'Reilly book "Enterprise Development with Flex...
A key task in the scope of Content Management, is Content Modeling - this is when you get raw content to fit into some common model of types and elements. Once defined, the types and their elements fit into a hierarchy (A.K.A - Taxonomy or "Content Tree"). To break this down a little f...
With a global recession looming, software development managers are being asked to slash resource budgets in 2009 while maintaining schedules. When you need to deliver more features with fewer coding resources, there is only one answer: hybrid development. Hybrid software development in...
High-performance databases are optimized for transaction processing and used by several industries around the world, notably financial services and health care. They are more commonly available on 32-bit Unix platforms (Solaris, AIX, HP-UX, and Linux). The trend is to 64-bit-enable the...
The open source community includes many early advocates of the recent wave of emerging SOA-related technology projects. Historically, however, open source has sometimes been considered a "late follower," with commercial products first to hit the market, and then followed by "me-too" op...
Any large Java source base can have insidious and subtle bugs. Every experienced Java programmer knows that finding and fixing these bugs can be difficult and costly. Fortunately, there are a large number of free open source Java tools available that can be used to find and fix defects...
Is software development a science or an art? The software industry treats it as a science. It uses processes like MRDs, PRDs, and functional specs to convert customer needs into software that solves their problems. Various roles like product managers, engineering managers, project mana...
The mouse was the original idea of Doug Engelbart who was the head of the Augmentation Research Center (ARC) at Stanford Research Institute. Engelbart's philosophy is best embodied, in my opinion, in the design of another device that he invented, the five-finger keyboard - with keys li...
One of the beauties of Linux from a business point of view is that it doesn't require the 'latest and greatest' hardware to run properly. This means you can increase the return on investments (ROI) for legacy hardware. As I'll show in this article, as in the case with virtualization, t...
One of the most exciting things about the software industry is how fast it moves. Software is constantly optimizing itself around the state-of-the-art. Inherent industry bottlenecks change cyclically every five years or so. Architectures and solutions change too. CPUs too costly? Enter...
Governance is currently a key topic for many IT functions. Its definition varies, but its key themes are true for all companies: effectiveness, efficiency, and reliability. Business value and risk mitigation are also at its center and represent a significant part of enterprise governan...
Understanding the complexity of AJAX at the browser level is critical to refining and debugging rich AJAX applications that leverage Web technologies such as JavaScript, Cascading Style Sheets (CSS), and XMLHttpRequests. Adding a third-party AJAX runtime heightens the complexity and su...
We'll build a servlet that will demo some new Java 5.0 features and do some basic tasks like creating a session to track user visits to multiple Web pages. This code can easily be extended to store a user ID in the session that will travel with her as the site is navigated. The value o...
