Guru: IBM i Experience Sharing Case 4 – Investigating Time-Sensitive Transaction Issues

June 6, 2022 Satid Singkorapoom

Among the central processing hardware resources in a computer system – CPU, GPU, memory, disk, PCI-Express I/O bus – disk has always been the slowest component. Even the latest flash disk or NVM-Express flash drive or card is slowest, but not by much. Back in the days of hard disk, disk I/O was the most popular cause of performance problems. From experience, I always looked at it first in my investigation.

The modern SAN flash disk can still be the performance bottleneck when it is not deployed properly, as I shared in Guru: IBM i Experience Sharing, Case 3 – …

Thoroughly Modern: Taking Charge of Your Hardware Refresh in 2022

February 14, 2022 Peder Lundblad

IBM i shops are well known for paying a premium for their systems because they are worth it, but they are also just as well known for hanging onto aging hardware a bit past its prime, which has its own kinds of economic costs in higher maintenance and operational costs as well as the risk of a failure in some key component of the hardware or of having an older operating system release that does not have a key security vulnerability or bug patched.

IBM does a very good job of keeping hardware technology cycles regular, and so there is …

Surprise! It’s IBM i Technology Refresh Time

September 13, 2021 Alex Woodie

IBM surprised the midrange world last week by announcing Technology Refreshes (TRs) for IBM i 7.3 and 7.4, which became generally available on Friday. The fall TRs, which typically are announced in October, brought support for the new Power10-based Power E1080 server in addition to a slew of enhancements to the operating system and surrounding IBM i products.

The big piece of news with the new TRs – IBM i TR 7.3 TR11 and 7.4 TR5 – is support for servers based on IBM’s speedy new Power10 processor, which is the first Power chip based on its 7 nanometer …

IBM i PTF Guide, Volume 23, Number 24

June 14, 2021 Doug Bidwell

Don’t get hyper this week, but the big thing happening in IBM i Land is a set of high impact and pervasive, or HIPER, PTF patches to all four current variants of the IBM i operating system. There are also tweaks to storage PTFs and for the MQSeries message queueing middleware that runs on various platforms from Big Blue, including IBM i.

Here is the rundown of PTF Groups by IBM i release level:

PTF Groups 7.4:
- HIPERs (High Impact/Pervasive)
- Temporary Storage PTFs
- MQ for IBM i – v9.0.0/v9.1.0/V9.2.0
PTF Groups 7.3:
- HIPERs (High Impact/Pervasive)
- Temporary Storage PTFs
- MQ for

IBM Unveils New and Improved IBM i Services

April 14, 2021 Alex Woodie

If you like IBM i Services — those SQL-based methods for executing a range of tasks in the operating system — then you’re in luck, because IBM has included a handful of new and improved IBM i Services in the Technology Refreshes (TRs) for IBM i 7.4 and 7.3, which were unveiled yesterday and ship this Friday.

IBM has developed an affinity for IBM i Services in the last few releases of the operating system. And why not? Users seem to like having a SQL-based alternative to CL commands and APIs. And since the IBM i Services are so easily …

Big Blue Unveils Spring 2021 IBM i Technology Refreshes

April 12, 2021 Alex Woodie

IBM tomorrow will announce the latest round of Technology Refreshes (TRs) for the current versions of the operating systems. With IBM i 7.4 TR4 and 7.3 TR10, IBM is focusing its efforts on extending automation across various components of the operating system, including the database, security, and high availability. But a surprise also awaits IBM i enthusiasts who are visually inclined.

IBM gave IT Jungle a preview of the announcements that will go public tomorrow, and (very kindly) gave us permission to cover them in today’s issue of The Four Hundred. That means that the announcement materials will not …

IBM Unveils New FlashSystem Storage Arrays

February 17, 2021 Alex Woodie

IBM last week took the wraps off three new FlashSystem storage devices, including the enterprise-oriented FlashSystem 5200 as well as two entry-level offerings, the FlashSystem 5015 and 5035. All three devices make use of speedy NVMe flash drives in the primary enclosure, but can be outfitted with traditional spinning and less-speedy solid state drives (SSDs) in the expansion enclosures.

Since early 2020, IBM has been phasing out its Storwize disk array line and emphasizing the FlashSystem line that replaces it. As part of that exercise, IBM renamed existing arrays, including the Storwize V5100, which became the FlashSystem 5100. It also …
