Many network security technologies are available these days—from tried and true staples such as network firewalls to newer developments such as Intrusion Prevention Systems (IPSs) and the new anomaly detection and Data Loss Prevention (DLP) technologies. Web Application Firewalls (WAFs) and IPSs are gaining some ground as forces such as regulatory compliance drive end-to-end security requirements. enterprise acceptance for some of the other newcomer technologies varies, but it’s clear that network firewalls are here to stay. They remain among the most important core technologies in the network security arsenal, which makes it important to understand…

Historically, compliance hasn’t been much of a problem in mainframe environments. The mainframe is a highly mature platform with well-established best practices, and mainframe professionals have generally had a pretty clear picture of what’s taking place in the environments they manage.

However, several factors are now making compliance on the mainframe a significant challenge:

• Increasing regulatory mandates • Increasing mainframe workloads • Decreasing mainframe staff resources.

Combined, these factors increase the likelihood that key compliance tasks will not be performed—or that they will be performed only…

Brand and product loyalty are increasingly scarce in today’s fast-paced and often fickle culture. Even in industry and business, change is often inflicted for its own sake— sometimes at the encouragement of what’s disparaged as “management by airline magazine.” So, it’s noteworthy when a company builds a steadily growing business that provides innovative, cost-effective, rock-solid data processing on one technology platform for 40 years. Of course, that platform—IBM’s mainframe—has evolved a bit since Antares Management Solutions’ corporate parent adopted it in the ’60s.<…

Platform wars will continue to be waged, and the voice of reason from seasoned mainframe professionals sometimes still goes unheeded when those who propose dumping the mainframe portray them as “big iron” bigots. One mainframer whose input was falling on his management’s deaf ears lamented, “It’s like I’ve been tainted because of my 20 years working with mainframes.”

As a mainframe executive, you’re wise to question the motives of zealots promoting a move away from the mainframe. Attempts to get off the mainframe are expensive and…

Managers of mainframe data centers can be forgiven if they don’t pay much attention to all the hype surrounding cloud computing. Amazon.com, Google, and a host of others are rushing to build highly virtualized, massively scalable, and, hopefully, bulletproof IT infrastructures accessible over the Internet or, to use the latest buzz phrase, ”in the cloud.”

Mainframe data center managers have seen all this before. They’ve considered the mainframe data center their company’s IT infrastructure cloud long before there was a cloud. Virtualized and highly scalable, bulletproof and accessible…

Parents strive for the best for their children, and in most households, that extends to a litany of manners imposed early on that make no sense to the kid who just wants to be a kid. Sit up straight; don’t talk with your mouth full; say please and thank you. As evolved adults, we realize these “constraints on our creativity” were our parents’ attempts at helping us learn how to play nice with others, employing respect and civility in what would otherwise be a chaotic world. And for that, we thank them.

Most of us are familiar with the traditional applications that have been running on IBM mainframes for years because of the mainframe’s inherent qualities of reliability, availability, security, performance, etc. With the introduction of the System z/10, Linux on System z, specialty processors, and a vastly improved TCO/ROI story: It sure seems that IBM should be racking up a boatload of new mainframe customers in a variety of industries. I haven’t noticed that happening yet. Topping my list of targeted businesses would be companies that depend on a system with five-nines uptime, that is…

Distress calls echo throughout the industry about high-cost implementations involving Service-Oriented Architectures (SOAs). In many organizations, across-the-board spending cuts threaten SOA’s potential, and that trend might endure awhile. Most published IT budgetary surveys anticipate growth in corporate IT spending for 2009 to be anemic or flat. According to Gartner, budget growth of 2.3 to 0 percent is most likely, with a worst-case projection of cuts in the range of 2.5 percent.

Ironically, SOA delivers considerable value for enterprisewide interoperability, which can improve operational efficiency. Incorporating mainframe-based resources into a Web services strategy or some type of SOA can no…

Applications running with dynamic SQL are ever-increasing. Without some methods to contain the onslaught of queries, performance drops and phone calls increase. What can a DBA do to remain sane and avoid a visit from the company’s vice president?

This article addresses common bottlenecks encountered in performance of applications containing dynamic SQL, and how to avoid them. While our primary focus is distributed applications that access DB2 for z/OS on the mainframe, most of these bottlenecks and their solutions arise with other DBMSs as well.

With the ever-increasing diversity of equipment to manage, the IT department’s job is becoming more and more complicated. Take, for example, two extreme cases found in many companies today: large mainframe computers and tiny portable devices, such as smartphones. The responsibility falls on the IT department to select both kinds of equipment and accompanying software. By default, IT personnel have to deploy both technologies and provide support services to users.

But the two cases are vastly different. On the one hand, mainframe computers are physically secure. On the other hand, portable devices are carried around…

IBM recently offered analysts some interesting perspectives on the size and growth of the mainframe platform. As reported in the March issue of the Mainframe Market Bulletin, IBM claimed the mainframe has seen a 20 percent compound annual growth rate in MIPS since 2003, with specialty engine capacity growing at a very impressive 93 percent. In the same presentation, IBM pointed out that the System z has increased its server market share from 17 to 33 percent since 2000, according to data from analyst firm IDC. These are quite impressive figures, and although they need to be treated with a great deal of caution, they…

With all the focus on legacy modernization techniques, approaches and alternatives, we often miss a key point: What kind of modern system are we really trying to build and what is our goal? To loosely paraphrase a classical line from Alice in Wonderland: “If you don’t know where you’re going, it really doesn’t matter how you get there.” In the long run, modernized systems that are founded on a solid hardware/software architectural platform with streamlined Total Cost of Ownership (TCO) will determine the true success of your legacy modernization initiatives.<…

In a Service-Oriented Architecture (SOA)-enabled enterprise, services and servers are a common good; they aren’t “owned” by a line of business or technology team. However, it’s possible to solve the technological challenges of SOA and still fail because the organization isn’t in sync with SOA design; organizational dynamics matter. The share-everything compliance challenge is just the beginning; the structure of an organization probably will have to change. Learn how you can transform your company into a Service-Oriented Organization (SOO) to reap SOA success.
