  • IBM Previews Virtualization Management Tool for Power-Based Boxes

    June 25, 2007 Timothy Prickett Morgan

    As the use of virtual machine and logical partition hypervisors becomes more common at the data centers of the world, the hypervisors themselves are rapidly becoming commodities. They are not, as you can tell from the prices that you have to pay for IBM‘s Virtualization Engine or VMware‘s ESX Server, quite yet commodities, and are certainly not free, but it is clear to just about everyone in the industry that over the long haul, the software that gets layered onto such hypervisors is going to be where money is made and where vendors are going to try to

  • Database Sales Grew By 14.2 Percent in 2006, Says Gartner

    June 25, 2007 Timothy Prickett Morgan

    The annual stats for the relational database market have come out from Gartner, and despite the advance of inexpensive and often open source databases that have modest support license fees, sales worldwide for databases grew by 14 percent in 2006, hitting $15.2 billion in sales.

    By relational database management system, Gartner is restricting its comparison universe to those databases that have SQL front ends, which means sales of flat-file databases (such as those that are popular on mainframes) are not included in the mix.

    As has been the case for many years, Oracle held its dominant position in the

  • Lawson Expects Better Results for Fiscal Q4 Than Anticipated

    June 25, 2007 Timothy Prickett Morgan

    There are two times when public companies talk out of turn with Wall Street: when things are going unexpectedly wrong, and when things are going unexpectedly right. ERP software giant and midrange player Lawson Software has sent out a note to Wall Street and to its investors to let them know that its fiscal fourth quarter ended May 31 went better than expected.

    Lawson will report its final financial results for the fourth quarter of fiscal 2007 on July 26, but wanted to let everyone know that sales are looking up. In the third quarter, Lawson went into the red,

  • MPack Hacker Tool Claims 10,000 Compromised Web Sites

    June 25, 2007 Alex Woodie

    A Russian-developed hacker tool called MPack was being utilized last week in a Web attack that has compromised an estimated 10,000 Web sites, primarily in Italy but also in other parts of Europe, security researchers reported. As the largest such attack in recent memory, MPack shows how sophisticated hackers and malicious software developers are getting at compromising network security, and ups the ante in the ongoing battle against cyber crime.

    Late Friday (June 15), computer security researchers started tracking the Web site hacks and resulting spread of malware, which some have dubbed the “Italian Job” because most of the infected

  • The AS/400 at 19: Predicting the Future–Or Not

    June 21, 2007 Timothy Prickett Morgan

    As a young student of math and engineering a few decades ago, I was drawn to these topics because they offered what seemed to my eyes a calculable and assuring degree of certainty in the answers they provided. I didn’t think about it at the time all that much, but math was particularly fulfilling because it had answers, and given a set of data and conditions, you could predict future sets of data and their conditions. In that idealized world, you can predict the future.

    Of course, the more I studied complex systems–either physics or aerodynamics–the more I got

  • Parameter Passing and Performance

    June 20, 2007 Ted Holt

    There are three ways to pass a parameter to a procedure: by reference, by value, and by read-only reference. These methods are not interchangeable, and passing parameters by value can have unfavorable effects on performance. In the following paragraphs, I explain why I make such a statement, I show you how to define parameters for performance, I list the performance figures from my testing, and I provide some recommendations for parameter passing.

    Before I go any further, let me get a couple of things out of the way. First, keep in mind that I am talking about you and the

  • Conditional Counting with Open Query File

    June 20, 2007 Hey, Ted

    Is there a way to make Open Query File (OPNQRYF) count records that meet certain criteria? I want to write a summary query, using OPNQRYF, that counts all records, and that also counts only the records that have a positive value in one of the numeric fields. Can OPNQRYF do anything like that?

    –Dave

    When I got Dave’s question, I told him that I thought it could be done, but I’d have to play with it to figure it out. A little while later, Dave had his query and I had another technique to share with you.

    It would be

  • What Is SMIOSTCPGT and Why Is It Eating My System?

    June 20, 2007 Hey, Joe

    We’ve been doing some performance analysis on our i5/OS V5R3 system and we’ve discovered that the SMIOSTCPGT process is producing an incredible number of synchronous disk operations, which could be slowing down system performance. What is SMIOSTCPGT and what can we do to stop it from bogging things down?

    –Joe

    Before I start this tip, I’ll come clean and admit that this question came from my own recent experience and it’s a problem I’m trying to find a solution for. I’m presenting the problem here as documentation for other administrators experiencing the same issue and to gather more information on
