It’s early October, which means leaves are changing colors, nights are getting colder, and IBM developers in southern Minnesota and elsewhere are gearing up the autumnal Technology Refreshes for the IBM i operating system.

With last week’s announcements of TR1 for IBM i 7.6 and TR7 for IBM i 7.5, which ship November 21, IBM has committed to delivering a slew of updates and new functionality across the range of IBM i system software, from application development to administration.

Before we get into the specific areas of IBM i, let’s cover the general enhancements it made with I/O handling. For …

The New Capabilities IBM Added To Navigator For i

April 23, 2025 Alex Woodie

The addition of multi-factor authentication (MFA) to IBM i 7.6 is the big news with the recent operating system update from IBM. But IBM has introduced new capabilities to other parts of the platform as well, and some of the biggest reside in Navigator for i.

As the strategic Web-based console for administrating the IBM i server, it’s natural that Navigator for i gets lots of attention. Whether you’re looking to monitor or manage the databases, inspect batch jobs, configure security, or monitor performance, Navigator for i is the one central place that lets you do it. You can, of …

IBM Bolsters New Nav With Job Scheduler And More

April 24, 2023 Alex Woodie

IBM i professionals finally can access the Advanced Job Scheduler from Navigator for i as a result of the new Technology Refreshes (TRs) that IBM unveiled on April 11. But the job scheduler is just one of a number of new capabilities that IBM is bringing to the snazzy new Web-based interface for administrators and power users, which Big Blue would very, very much like for you to use.

When IBM debuted the new Navigator for i in the fall of 2021 with release of IBM i 7.3 TR11 and 7.4 TR5, it figured it had the luxury of time …

IBM Publishes Power10 Performance Optimize Guide

December 7, 2022 Alex Woodie

IBM i shops looking to squeeze the most performance out of their Power10 servers have a lot of options available at their disposal. IBM covers many, if not all, of them in its latest performance paper, titled “IBM Power10 performance optimization for IBM i,” which it released last week.

The Power10 is the most powerful processor IBM ever built. Compared to the Power9 processor, the Power10 delivers 20 percent to 30 percent higher performance per core. And with 25 percent more cores per socket, that means oodles of more processing power to do useful work.

At a system level, the …

When we drive our cars, we hope to avoid red lights and traffic jams, because we all hate waiting immobile in traffic. I’m sure that you are aware, fully or subtly, that active jobs in any computer system can encounter wait as well. The IBM i developer team has categorized many types of wait.

In this article, let’s look at CPU Queuing wait time. Let’s see how we can interpret and address it in a sensible way to resolve poor performance. I’ll try to provide you with a useful approach to wait time analysis using a gloriously useful performance reporting …

Guru: Understanding Database Performance Using The Performance Data Investigator, Part 2

June 28, 2021 Dawn May

This is the second in a two-part series on how you can use the Performance Data Investigator (PDI) to investigate performance of Db2 for i. While the SQL Performance Center in Access Client Solutions is more commonly known than PDI, using both tools is a good way to analyze database performance.

In Part 1, I reviewed the Database content package, focusing on the charts for I/O reads and writes, SQL CPU utilization, and database locks. In this tech tip, I continue by reviewing the charts related to SQL Cursor and Native DB Opens as well as the SQL Performance …

Guru: Understanding Database Performance Using The Performance Data Investigator, Part 1

June 21, 2021 Dawn May

This is a two-part series on how to use the Performance Data Investigator (PDI) for investigating performance of Db2 for i. While the SQL Performance Center in Access Client Solutions is the tool of choice for Db2 performance analysis, there is valuable information that you can get from using PDI. PDI is often a useful starting point to help guide you in the correct direction when trying to identify performance issues. In my experience, PDI is under-utilized for Db2 investigation. For those not familiar with PDI, you may want to read the article, Getting Started with the Performance Data Investigator …

The Ultimate Set Of Tools

December 14, 2020 Rob McNelly

Those of a certain age will certainly remember the moment in Fast Times At Ridgemont High when Jeff Spicoli got himself into a bind after he wrecked his friend’s car. Luckily, Spicoli’s dad was a TV repairman, and he had an ultimate set of tools. Spicoli knew that with those tools, he could fix it. That level of confidence is intoxicating, although in this case it was possibly misplaced.

I have a friend that lives around the corner from me that actually does have the ultimate set of tools, and knows how to use them. For example, he recently rebuilt …
