Immutable Table Function

Should DB2 have an Immutable Table Function?

I love hearing about Blockchain; if you are involved in Fintech, then surely by now you have heard a lot about it, and that it holds a tremendous amount of promise for Internet business. Fundamentally, it guarantees the validity of a transaction.  Blockchain is a ledger of all transactions; a ledger cannot be changed, making the requirement for a third party to process transaction payments unnecessary.

What’s waiting round the mainframe corner?

Anyone who has been working on mainframes for any length of time knows that things are always changing. Many people can remember when DB2 was new (1983), the client-server period, and the need for Service-Oriented Architecture (SOA). And, I’m sure, can come up with a much longer list. I don’t want to look backwards at old ideas, I want to take a whirlwind look at what’s coming soon to (at least) a presentation near you.

2020 vision

I was working recently with a mixed bag of people from a company, who were trying to predict the future and see how that company needed to change in order to get where they thought they ought to be going. One issue came up fairly quickly, and that was that 2020 isn’t that far ahead. As a result, the group started to think about 2025 as date for the changes to be made. The room had a mixture of IT people, execs, a variety of managers, and a number of people from different parts of the organization. I thought it would be interesting to contemplate some of the ideas that came up at the session.

Data Centers, Mainframes and the rest

Data Centers, Mainframes and the rest!

When compared to an x86/distributed server environment, the operational costs of the power consumption versus IBM’s Mainframe z Systems are half, while the performance is 30 percent greater (using z Systems as an example.)

So let’s think about that for a minute!

X86/Distributed server power consumption is double that of an IBM Mainframe?

Mobile Computing, the Mainframe and z/OS Connect

Mobile computing has had a seismic impact on IT and the modern computing architecture—and it will continue into the foreseeable future.

Mobile devices—smartphones and tablets—have overtaken traditional computing devices such as desktop and laptop computers in terms of how we interact with service providers and retailers. And this transition is even more pronounced among the young. It is not uncommon for a smartphone to be used non-stop during the course of the day, not just for making calls, sending and receiving texts and keeping up with email, but also to shop for the best price, make purchases, check bank balances, make travel arrangements, and more.

Blockchain A Great Candidate For The Mainframe

Most of you are undoubtedly familiar with one of the biggest buzz terms in the industry by now: blockchain. If not, have a quick read of a great article from a few months ago in The Wall Street Journal, CIO Explainer: What Is Blockchain?

Punk’s not dead and neither is the mainframe

Admittedly, I’m as much a music fan as I’m a technophile—perhaps it’s this combination that makes it easy for me to draw comparisons from the punk music genre to that of the mainframe. After all, punk hasn’t changed—it has simply evolved. From the early days of 1970s New York City, to the United Kingdom bands of the 1980s, to the bands that spawned the sound track to the X Games—and now the bands that play the Dew Tour—the music genre has influenced our social fabric, taking on a new audience and a new meaning for every generation.

Don’t get fooled by the Mainframe FUD

I’ve been seeing FUD (Fear! Uncertainty! Doubt!) articles like this one for years now and while it’s pretty easy to see through them, this time I decided that I just have to say something. The gist of the article, as the title suggests, is that legacy systems are old and clunky, and are holding the banks back and preventing them from benefiting from the modern features that they want: personalization, predicting customer needs, delivering on improved customer satisfaction, etc. (Legacy systems stand in the way of customisation for banks)

Four ways Mainframe shops can Embrace Mobile

Part 4: New Online Processing and Data Storage

This is Part 4 of a 5-part series about how mainframe shops can embrace the needs of new mobile workloads.

Last time, we looked at a new online processing solution that would replace the existing online processing, but leverage all other parts of the legacy infrastructure. In this post, we’ll take a close look at a similar solution that also leverages some of what exists, but creates all new online processing as well as new database components.
