Over the last several years, there has been tremendous growth in the use of online banking, smartphones, tablets and other remote devices. In addition, there has been astronomical growth in the development of applications that can access business information via the Internet. This has led to an increasing demand for online transaction processing (OLTP) data via remote access.

Before the advent of smartphones and tablets, most remote data requests were generated using interactive screen-oriented transactions. Today, customers can use smartphones or tablets to access account information, make purchases or just browse Websites much like customers once window…

There has always been a need to be able to quickly determine the size and complexity of a program, especially for development managers, as they consider scheduling, cost estimations, assigning projects to staff and projecting expected completion dates. The article “When Size Does Matter: The Evolution of Techniques to Gauge Program Size,” available at http://entsys.me/uuazl, discussed attempts to do this using lines of code and the Halstead Metrics. The Halstead Metrics help developers glean more insight into the complexity of a program by looking at the actual verbs and variables used in the program…

One of the most frightening topics for a newcomer to z/OS is disk storage management. With more than 50 years of history, beginning with the introduction of the IBM System/360 in 1964, mainframe disk systems have had a long time to mature and develop, and in the process, have achieved an extraordinary level of both reliability and complexity. Despite this high level of sophistication, the main architecture used in z/OS disk administration—System Managed Storage (SMS)—is really quite simple to understand and use.

A Bit of History

IBM introduced SMS in 1989 as…

Compliance is no longer an optional facet of doing business. Government agencies, service providers, even customers may require a declaration and proof of compliance. Where it used to be that ad hoc reporting could fill the requirement for compliance documentation, business today must have a well-documented and defensible set of standards that prove their compliance to relevant standards. This means standardized tests, documented results and quantifiable reports. And it isn’t enough to meet the requirements of your home government, but now you must meet the privacy and compliance requirements of any country wherein your data resides.

Being a parent of several teenagers (and a former teen myself), I’ve seen too many times how bad choices, reinforced by other bad choices, can lead to extraordinarily bad outcomes—even when intentions are pure and noble. The same seems to hold true in the realm of technology.

Years ago, the industry sought to solve the problem of growing capacity demand (and associated costs) by moving from internal storage to external arrays. Nothing wrong with that, since direct attached storage, like DASD in mainframes, tended to be mostly managed via the host operating system.…

At the time of writing, it is approaching the 50th anniversary of the announcement of the IBM System/360 aka "The Mainframe". By now, anyone who's been even tangentially involved with this beast is familiar with the number of times it's been written off: most notably in 1991 when the prediction was made that the last mainframe would be switched off in 1996.

 Of course, that never happened.

There have been notable losses, including one site dear to my heart, but the mainframe has one thing in common with Mark Twain: "rumors of my death have been greatly…

Today’s Fortune 500 companies are embracing distributed techniques to access mainframe data on DB2. Although online transaction processing (OLTP) workloads still dominate DB2’s local processing, more applications, such as data warehousing analytics, run remotely as distributed tasks. The interesting part of distributed DB2 is the terminology; it has its own set. If you spend time dealing only with the local side, some of these terms may be new, maybe even confusing in some rare cases. Here’s a distributed terminology refresher using a couple of subsystem parameters that affect distributed data facility (DDF) processing: MAXDBAT…

Where were you 50 years ago on April 7, 1964? For most people in IT, that’s a crazy question because most of them weren’t even born yet. But it’s definitely a fair question for many mainframers. That’s right, many of us mainframers are a bunch of old-timers who will have no problem with that question. The fact that so many mainframers are nearing retirement age is an important issue, but not one that will be dealt with here.

So back to the original question: I was a 2nd Lieutenant in the U…

The item rocketing to the top of today’s enterprise threat list is cyber-risk. It’s not surprising. With the increasingly central role that information plays in creating value, any threats to data that’s stored or shared online can represent a direct and potentially crippling hit to a company’s corporate reputation, customer satisfaction levels or ability to innovate.

The security landscape is getting more complex by the day, making the notion of being secure a moving target CIOs or Chief Information Security Officers (CISOs) are endlessly pursuing. It’s ironic…

In the past, when data needed to be securely transported through a network, the common solution was to protect the transport layer through the use of Transport Layer Security (TLS) or Secure Sockets Layer (SSL). This enabled data to be transported from point to point in a secure manner. While this was good, it quickly became apparent it wasn’t flexible enough to protect the complex services and application program interfaces (APIs). This is due to the fact that most times these services and APIs are of composite nature and consist of many smaller aggregated components. Providing security…

Recently, there was an intriguing article published by Chris Kanaracus on www.computerworld.com. The author quotes Ken Rudin, Facebook analytics chief, who was talking about how Big Data needs more than Hadoop.

It’s always interesting to read about the practices of successful organizations dealing with large amounts of data. In his presentation, Rudin talked about the standard topics of combining Hadoop with databases and choosing the technology suitable for the task at hand. For an analytics-minded person, these are important and sensible guidelines that should be followed.
