  • Disk Array Sales Cool Off In The First Quarter

    June 16, 2014 Timothy Prickett Morgan

    Here is something that a lot of people probably didn’t expect: Disk array sales took a dive in the first quarter of the year, particularly at the high end of the market.

    According to the latest market research from IDC, the world consumed a total of 9.9 exabytes of capacity on the combination of internal and external disk arrays from January through March, representing a mere 19.9 percent increase in capacity on a year-over-year basis. In the fourth quarter, as we previously reported, total disk array capacity shipped was up 26.2 percent to 10.2 exabytes, reversing several quarters

  • Sundry I/O Enhancements For Power8 Servers

    June 16, 2014 Timothy Prickett Morgan

    In addition to the new four-core Power8 system aimed at IBM i customers that came out last week, IBM made a bunch of I/O and storage announcements relating to the new machines.

    In announcement letter 114-094, which came out on June 10, IBM said that it was making its existing two-port communications adapter (that is feature 2893 and 2894) orderable for machines running IBM i. These replace the two-port asynchronous communications adapters (features 5289 and 5290) that were announced with the new machines back in April. Those cards are now not going to be supported.

    IBM does not yet

  • Modernization Train Makes A Run Through Europe

    June 16, 2014 Dan Burger

    The era of modernization is upon us. There are projects in the planning stages, in midstream, and completed—all indicators that IBM midrange shops interested in adopting new technologies where there are good reasons to do so. COMMON Europe recently concluded an IBM i Enterprise Application Modernization Tour that highlighted many of the topics and technologies that the IBM i community is showing interest in adopting.

    There’s a multitude of ways to approach modernization, and no one knows that better than Tim Rowe, business architect for IBM i application development. Rowe, the designated modernization evangelist, provided the IBM presence on the

  • Custom Perspectives In RSE

    June 11, 2014 Susan Gantner

    In my earlier tip, Who Needs ?, I described how to create a custom perspective and I also described one scenario when custom perspectives come in handy. I promised to follow that up with another way to use custom perspectives.

    I’m often asked questions such as:

    • How do I keep my Outline from disappearing when I’m in full-screen edit?
    • How can I see my RPG Indentation view alongside the full-screen editor view of the source member?

    Custom perspectives can be used as one answer to both questions.

    Of course, when you’re in full-screen edit, you can “peek” at any

  • Surmounting Identity Column Challenges

    June 11, 2014 Ted Holt

    Using an identity column is a wonderful way to ensure that each row of a table (record of a physical file) has a unique identifier. It sure beats storing the next batch (invoice, transaction, etc.) number in a data area or a one-record database file. Here are a few things to keep in mind when inserting rows (writing records) into a table that has an identity column.

    1. Let the system assign the value to the identity column. You do this by specifying GENERATED ALWAYS or omitting the GENERATED option when you create the table.

  • Admin Alert: Reorganizing IBM i Files To Improve Disk Performance, Part 1

    June 11, 2014 Joe Hertvik

    One of the easiest ways to improve IBM i performance is to make sure all your critical files are reorganized on a regular basis. Files with excessive deleted records take longer to read because each returned record block contains deleted as well as active records. The next two columns, I’ll present a template for detecting and reorganizing your most active files to improve disk processing efficiency.

    Why We Reorg

    There are several good reasons for reorganizing files with large numbers of deleted records, including:

    1. Conserving disk space–If your disk is filling up, you can retrieve a fair amount

  • Thanks For The Cheaper, Faster Memories

    June 9, 2014 Timothy Prickett Morgan

    The new Power8 systems started shipping last Friday, and this week, in our ongoing coverage of the new hardware and software technologies embodied in the systems, we are going to take a look at the memory subsystems in the new machines. There are a slew of new technologies that have been added to the Power8 machines so the memory can keep the processor cores well fed and humming along through their work.

    The Power8 chip has two DDR3 main memory controllers, one on either side of the chip. Some of the DDR interfaces that were previously on the Power7+ controller

  • Apache Web Server Upgrade Path Handled By i 7.2

    June 9, 2014 Dan Burger

    The Apache Web server should not be a mystery to anyone in the IBM midrange community. But the awful truth is that more IBM i advocates are familiar with SEU and PDM than any topic that’s within 10 miles of the Web. To everyone in that tribe, the latest enhancements to the Apache Web server and the WebSphere Application Server are sadly inconsequential. For those who see the Web in their future, this is an opportunity to keep current with technology.

    Fresh from the oven IBM i 7.2 brings support for the Apache HTTP Server 2.4, which has been available

  • SAP Hana For IBM Power Officially In The Works

    June 9, 2014 Alex Woodie

    IBM and SAP last week started talking publicly for the first time about running the HANA in-memory database on Power to create a potent solution for combined analytics/transactional workloads. There’s no firm date yet when we’ll see Power HANA, but the work is progressing as part of a test and evaluation program, the mega-vendors say.

    The notion of running the in-memory HANA database on IBM’s Power processors is not a new one. Executives with SAP told IT Jungle it was a possibility when we spoke with them about it last year. “Power is something that we’re looking at very

  • Mad Dog 21/21: The Show-Me State

    June 9, 2014 Hesh Wiener

    Between 1981 and 1993, IBM liquidated an extraordinary asset. Its value had been building since Thomas J. Watson became head of Computing-Tabulating-Recording Company, IBM’s birth name, in 1914. That asset was a vast base of rental equipment. Rentals had fueled and stabilized IBM and fostered its binding relationship with customers. Once gone, that rental base could never be rebuilt.

    At the helm when this sea change began was John Opel, who hailed from Missouri, the Show-Me State. He probably didn’t understand what IBM showed him. His successor, John Akers, caught on, but by then it was too
