IBM Readies Mainstream Power9 Iron For Launch

February 5, 2018 Timothy Prickett Morgan

The natives are getting restless, as my parents used to say when we were getting hungry. And the IBM i and AIX bases are definitely getting restless to know what Power9 iron that will be able to run Big Blue’s own operating systems in conjunction with the PowerVM server virtualization hypervisor. They also want to know if IBM is going to give customers a big improvement in price/performance compared to Power7+ and Power8 machines that are still widely available in the channel.

In short, they want to plan their future, and after four years of waiting, it is time.

IBM …

Reckless or Riskless: IBM i App Dev Experts Talk Security

February 5, 2018 Dan Burger

It is safe to say that your most sensitive and most valuable data is not safe. The threat of stolen data is a reoccurring nightmare for executive management who are mystified and somewhat dumbfounded by the number of vulnerabilities in their IT systems. Not all of them worry about the same things or are hearing the same strategies from their IT experts.

Most can agree that what’s been done in the past isn’t going to cut it in the present, much less the future. One of the holes in the wall that protects data is at the application level. Existing …

Guru: Three Suboptimal I/O Practices

February 5, 2018 Ted Holt

I have on numerous occasions looked at source code that I had written in previous years and asked myself, “Why on earth did I do that? What could I have been thinking?” We live and learn, or at least we hope we learn. Today I share three database practices that I see from time to time that can be simplified. Maybe there’s something for you to learn today.

Before I share the three examples, let me say that I do not consider the more cumbersome code to be wrong. To my way of thinking, any code that produces the correct …

Will Blockchain Impact IBM i?

February 5, 2018 Alex Woodie

Lately there’s been a lot of talk about blockchain, in both the IT press and the mainstream media, which is telling. Most of this talk centers around digital currencies like bitcoin that are based on blockchain technology. But because of the media-fueled speculative bubble that’s pushed digital currency values through the roof, it’s tough for a rational being to separate the incredible hype from the underlying reality.

What’s interesting about the whole blockchain-bitcoin discussion, however, is how many smart technology folks have come out and basically said that while the digital currencies are interesting but not ground-breaking, the underlying blockchain …

The Persistence Of The IBM i Platform

February 5, 2018 Timothy Prickett Morgan

Talking about switching platforms is one thing, and it is relatively easy if you are talking about moving from Unix infrastructure servers based on RISC servers to machines that are going to run essentially the same workloads on Linux systems based on X86 processors. Leaving the IBM i fold, particularly for customers who have created their own applications, is another matter entirely.

That, in a nutshell, is one of the main reasons why the IBM i platform, in its many different incarnations in the past 30 years, has persisted. The database is the stickiest piece of software in the datacenter, …
