IBM is saying it will sell hardware bundled with software and services by guaranteeing a bottom-line outcome for the solution. That means mainframe IT buyers need to rethink their benchmarking and comparative criteria—including judging by return as well as cost.

In December 2010, IBM Connect, the annual IT analyst summit hosted by the company’s Software Group (SWG), provided big news for mainframers. Particularly notable was IBM’s development of new ways of integrating products into solutions to meet specific customer needs. The company presented its approach as if there was one new,…

Those who have had a childhood will recognize the title as a poem in A.A. Milne’s “Winnie-the-Pooh.” This poem makes an important point about IBM Big Blue’s mainframe cloud strategy: Cloud computing is about a fully enveloping atmosphere of virtualized software, hardware and services, and by using the mainframe, IBM makes the deployment and operation of such a cloud exceptionally effortless. Eeyore might not believe this, but you should consider it.

Here we continue exploring the information you need to do your job well. This column examines questions that miss the point by invoking false YES/NO answers.

After the recent oil spill in the Gulf, some people think we shouldn’t permit deepwater drilling anywhere, since clearly the risk is too great. Others claim we must continue deepwater drilling, since we’re so dependent on oil. The more important question underlying this impossible-to-resolve split is, “If we do have deepwater drilling, how can we know that the people doing it are following the rules…

Moving to a standardized management and governance environment offers considerable benefits for heterogeneous IT environments. This article explains how IBM’s new hybrid zEnterprise server and zEnterprise BladeCenter Extension (zBX)/Unified Resource Management offering can be used to overcome conflicts between centralized and distributed systems.

Types of Organizations

IT buyers build three types of computing environments:

  • Unified homogeneous IT organizations are characterized by their choice to standardize on a single platform architecture (usually x86-based), a single infrastructure, such as Java 2 Enterprise Edition (J2EE) or Microsoft .NET, and standardized management…

For this issue, I wanted to write a column that’s upbeat. For starters, it’s time to speak up and acknowledge that mainframe executives deserve a lot of credit. Too few people really appreciate how difficult it is in a heterogeneous environment to keep up with so many moving parts, providing servers and networks that always stay up. At times, it may seem impossible to live up to expectations as support costs continue to mount up, and take up the majority of IT budget allocations. Runaway server farms are enough to make you tear up, which…

Just think about all the choices you have in computing devices for your workforce—it’s enough to make you feel overwhelmed. There are so many different form factors, and for each, slight variations in shape, size, and physical features. To make some sense of all this, let’s look at the five major types of mobile device: cell phones, smart phones, ultra-mobile PCs, tablets, and laptops.

If your needs are limited to phone calls, text messaging and simple calendar functions, cell phones are by far your best bet. Why complicate matters with a…

The mainframe remains one of the most effective methods for batch processing and a large number of organizations rely on it. However, maintenance is a key consideration for any mainframe batch application. Large batch applications fail for various reasons. These batch applications are commonly used for overnight processing and have strict Service-Level Agreements (SLAs) that make quick failure resolution imperative. This article presents an effective solution to automate most of the manual activities required while restarting any failed batch stream.

Forensics is a collection of tests and techniques used together to uncover detailed evidence that can be used to help reconstruct an event. This article describes how network-related forensic tools can be useful to DB2 for z/OS.

Victims and Suspects

Network access to DB2 for z/OS is provided by Distributed Data Facility (DDF), a built-in component. Any application server or client, running on z/OS or any platform, can use TCP/IP to access DB2 though DDF. In this environment, there are many potential victims of bad network service and performance (see Figure 1).<…
