• The Battle Of The Single-Core IBM i Machines

  July 20, 2020 Timothy Prickett Morgan

  Last week, IBM announced a revamped lineup of entry Power9 systems, including a new single-core variant of the Power S922 server aimed at IBM i shops that will replace the long-running Power S812 and the Power S914 for IBM i customers with modest compute performance and storage requirements. The announcement of the single-core Power S922 comes just as the stay of execution for the Power S812 will be running out on August 31.

  In the issue last week, we told you that we didn’t have a lot of the details on the pricing of the new single-core Power …

• ERP Deployments Shift Cloudward, Even On IBM i

  July 20, 2020 Alex Woodie

  Applications of all sorts are moving to the cloud, including the critical ERP systems that businesses rely on to automate processes. That’s been the trend for some time in the industry as a whole, but it’s also having an impact on the IBM i community, which is becoming cloudier by the month.

  While on-prem deployments of IBM i still dominate, the cloud portion is growing. Nearly one-quarter of IBM i shops have IBM i resources running in the cloud, according to HelpSystems’ 2020 IBM i Marketplace Study, including 6 percent who are cloud-only and 17 percent who run …

• Guru: Dynamic Arrays Come To RPG

  July 20, 2020 Jon Paris

  Some 12 months ago, when the 7.4 release was announced, I wrote the Guru Tip “7.4 Brings New RPG Goodies” describing the features of 7.4 that were also available on 7.3. I said at the time that I would return later to discuss the 7.4-only features. So now that a significant number of shops have access to 7.4 that time has arrived.

  Dynamic arrays are the answer to the perennial programmer question: “Just how big do I need to make this array?” In my experience it doesn’t actually matter how big you make it, at some point down the road …

• Unperspective: I Am Weird, You Are Weird

  July 20, 2020 Trevor Perry

  People are weird. All of them. You are weird. I am weird.

  I believe in this so much that in my past I started a company with P.A.W. in its name. The fact is, it’s true, but not quite how you think.

  The Webster’s Dictionary definition of “weird” is short, including “of strange or extraordinary character: odd, fantastic.” Odd is defined as “differing markedly from the usual, ordinary, or accepted” and “not regular, expected, or planned.” Fantastic is defined as “so extreme as to challenge belief.”

  Taking a different look at weird, it’s easy to see where we have been …

• IBM i PTF Guide, Volume 22, Number 28

  July 20, 2020 Doug Bidwell

  The action never stops here at the IBM i PTF Guide. Which is probably a good thing because if a platform isn’t being constantly updated, expanded, tweaked, and fixed, then it probably is not going to live for much longer in this fast-changing world. No one can say that about the IBM i platform. Nope.

  So for you security buffs, check this out. Security Bulletin: BIND for IBM i is affected by CVE-2020-8616 and CVE-2020-8617, which has an insanely long link buried here. The link above provides details, but the gist of it is also here by release: …

• IBM Revamps Entry Power Servers With Expanded I/O, Utility Pricing

  July 14, 2020 Timothy Prickett Morgan

  Believe it or not, but it has been two and a half years since the first Power9 server shipped and it has been more than two years since the entry Power Systems machines – that would be the Power S914, the Power S922, and the Power S924 machines, code-named “ZZ” after the country-rock-blues band from Houston – were first announced. And today, these machines are getting an I/O makeover.

  And specially for IBM i shops, IBM is rolling out a single-core version of the Power S922 that will offer better bang for the buck as well as lower acquisition cost …

• Thoroughly Modern: Why You Need An IT Strategy And Roadmap

  July 14, 2020 Timothy Prickett Morgan

  (Sponsored Content) What makes a modernization project successful? Is it the right software and tools? Having the right people on the job? Completing the project on time and on budget? Some might argue that all of the above contribute to the overall success of these initiatives. But the experts at Fresche will tell you that building a comprehensive strategy and roadmap is the most important part. It’s the secret sauce that ensures that the project provides business value and that requirements are mapped out before you start. After all, failing to plan is planning to fail.

• Guru: The Case for Mixed-Case Procedure Names

  July 14, 2020 Paul Tuohy

  Using mixed case makes source code easier to read and easier to debug. I programmed in all upper case for many, many years, so I don’t recoil in horror when I see something in all uppercase. However, it’s a bit more difficult for developers who aren’t quite as long in the tooth as I am. To them, all uppercase is pretty abhorrent and bad (and I don’t mean bad as in good).

  There is a potential case issue with subprocedure names: there are at least three places on the system where the system shows subprocedure names in uppercase, regardless of …

• The Path Truly Opens To Alternate Power CPUs, But Is It Enough?

  July 14, 2020 Timothy Prickett Morgan

  If you have a few tens of millions of dollars to spare and you want to set up a foundry partnership with either Globalfoundries for 14 nanometer chip making technologies or with Samsung for 7 nanometer technologies and then create your own Power processor, things just got a little bit easier. Big Blue has open sourced one of its Power cores through the OpenPower foundation and now anybody and everybody can grab it and design a new central processing unit around that core.

  Don’t get too excited, but get a little excited. Let me explain.

  We still believe in the …

• IBM i PTF Guide, Volume 22, Number 27

  July 14, 2020 Doug Bidwell

  Welcome to the second half of 2020 after a brief holiday hiatus from The Four Hundred and therefore the IBM i PTF Guide.

  There is another new HIPER for the Virtual I/O Server, or VIOS, which again we know all of you IBM i shops love dearly. The HIPER is IJ25390, and it is for slow TCP performance with the Virtual Ethernet adapter and large send. Here is some more on that LSO – short for large send offload – and specifically a link that explains it better than we did two weeks ago, plus another link to a …
