• Breathing New Life Into Your POWER7 And POWER7+ Systems

  November 30, 2020 Timothy Prickett Morgan

  This is a hard lesson for people to learn, but savvy IT organizations certainly do learn it – some decades ago, some only now. And that lesson is that not every application slowdown and performance bottleneck in a system is directly related to the clock speed or throughput of the central processor. While the processors are indeed central, a system is comprised of main memory, storage, and network I/O, and tuning up a machine as many times as not means bolstering these other components to help the CPU better do the job that is latent in its particular feeds and …

• Big Blue Revives IBM i 7.1 With Power9 Support

  November 16, 2020 Timothy Prickett Morgan

  We don’t get surprises very often in the Power Systems market, and even fewer in the IBM i sub-market. But last week, we did get a surprise – and it was a pleasant one – as Big Blue decided that it was going to allow for IBM i 7.1, which has long since been removed from marketing and which was just recently given extended extended support through April 2023, to run on selected models of the Power Systems line using Power9 processors.

  That IBM would allow for this is remarkable, and it shows the economic and technical difficulties that many …

• Tweaks To Power System Iron Complement TR Updates

  October 12, 2020 Timothy Prickett Morgan

  Back in July, IBM upgraded the peripheral I/O on several of its Power9-based servers with more PCI-Express 4.0 bandwidth capacity, and now IBM is offering the increased bandwidth on several machines tuned up for running SAP HANA in addition to making a number of other hardware enhancements and withdrawals.

  In announcement letter 120-054 you will get the feeds and speeds of the updated Power H922, a two-socket, 2U server, and in announcement letter 120-055 you will get the feeds and speeds of the updated Power H924, a two-socket, 4U system. As far as I can tell, the machines are essentially …

• Guru: Qualified Files – Underused and Unappreciated

  September 14, 2020 Ted Holt

  When IBM adds a new feature to the RPG compiler, they do so for a reason. That’s why I try to learn new techniques. I hope they’ll improve the quality of the source code I write. One relatively new feature that I do not see widely used is the qualified file. In the following paragraphs, I’d like to tell you why I like qualified files and how to use them.

  To understand the need for qualified files, it may be good to begin with a brief lesson on the history of the RPG language. When RPG was originally developed, the …

• IBM’s Possible Designs For Power10 Systems

  August 31, 2020 Timothy Prickett Morgan

  In the past two weeks, we have been telling you about the future Power10 processor that will eventually be able to support the IBM i platform as well as AIX, Big Blue’s flavor of Unix, and Linux, the open source operating system that is commercially exemplified by IBM’s Red Hat Enterprise Linux distribution. The leap in performance with Power10 is akin to those we saw between the generations spanning from Power6 through Power9.

  This week, we want to contemplate the systems that will be using the Power10 chip and how they will be similar to and different from past and …

• Cobalt Iron Supports Multiple LPARs with VTL

  July 22, 2020 Alex Woodie

  IBM i shops will be able to back up multiple LPARs to an individual virtual tape library (VTL) from Cobalt Iron, the company announced recently. The new capability overcomes a limitation that has existed since the company started to support IBM i with its data protection service a couple of years ago.

  Cobalt Iron is a Lawrence, Kansas-based provider of enterprise data protection services. The company’s flagship offering, called Compass, provides backup, recovery, and related services for or all major computer platforms, including servers running on-prem, virtualized environments, and systems and applications running in clouds.

  Some of Cobalt Iron’s customers …

• 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 …

• Guru: One Way To Deal With Two Null Formats

  July 8, 2019 Ted Holt

  Hey, Ted:

  We are building a new system and want to use modern programming and database techniques. I have had quite a time trying to get nulls to act right. It gets confusing fast because RPG handles them differently than the way embedded SQL does. When using SQL for I/O, how do we handle the two null formats?

  — Brian

  There are several ways to go about the “problem” of nulls. Let me give you one simple method, but keep in mind that it’s not the only way.

  First, let’s create a table and put some data into it.

• Speaking The SQL Lingua Franca On IBM i

  June 3, 2019 Timothy Prickett Morgan

  No matter what the job is, we all start out somewhere that is pretty far from being an expert and we depend on our elders and mentors to help us learn all the tricks and get good at the work.

  So it is with the nearly ubiquitous database query language, Structured Query Language, or SQL for short. It started out in the head of IBMer Ted Codd back in 1969, which was coincidentally when the System/3 minicomputer launched and its successor many generations later, the System/38 in 1978, was the first IBM system and the first system in the world …

• Deep Dive On IBM i 7.4 And IBM i 7.3 TR6 Hardware Limits

  April 29, 2019 Timothy Prickett Morgan

  As everybody knows by now, IBM has announced both the Technology Refresh 6 for IBM i 7.3 and the shiny new IBM i 7.4 release. We did a brief overview of these operating system releases in last Wednesday’s issue, concurrent with the launch and ahead of their respective May 10 and June 21 general availability dates, to put them into perspective. Now, it is time to get into the nuts and bolts and bits and bytes of what Big Blue has announced.

  Rather than try to do it all in one story or possibly two, we are breaking it …
