Today’s modern IT organizations are challenged by the need to improve rapid delivery of critical business services. Each business service relies on successful completion of complex workloads that can be spread across multiple applications and platforms. In such complex environments, a single failure can have a significant impact on an organization’s ability to improve responsiveness to deliver goods and services to the business.

Dynamic data centers depend on the right combination of tools and technology to extract and analyze business and operational information. Mining data can reveal patterns that can help ensure critical…

Previous articles (see the “References” section) discussed the tremendous benefits accrued from using the CICS Open Transaction Environment (OTE), ranging from improved multiprocessor exploitation to reductions in software license charges. In this final article, we take a closer look at the CPU savings seen in large CICS/DB2 applications after they’re converted to threadsafe, as well as the critical elements of a successful conversion, including:

• How to identify programs that offer the greatest potential savings • How to determine the actual savings available compared to the potential savings • How to identify…

Since POWER6, IBM has provided a way to move a logical partition (LPAR) between servers while it’s running, allowing you to migrate an LPAR or LPARs without any downtime. This feature is called Live Partition Mobility (LPM) and is provided by the Enterprise Edition of PowerVM, which must be installed on all servers involved.

LPM is used for multiple reasons, ranging from server consolidation, server migration and workload balancing to completely evacuating servers so they can be shut down for planned maintenance or other purposes. LPM can be used to move Linux and AIX (5.3 and…

Irish writer and poet, Oscar Wilde, once said, “Life is simple and the simple thing is the right thing.” That’s the driver behind the creation of the IBM Explorer for z/OS (z/OS Explorer).

With the release of z/OS Explorer, IBM addresses two major concerns that exist with many, if not all, z/OS sites:

• There’s a learning curve for newbies. • Complexity creates a “choppy” user experience.

Manipulating z/OS jobs and files is intuitive for those familiar with IBM&rsquo…

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…
