• IBM i PTF Guide, Volume 22, Number 2

  January 15, 2020 Doug Bidwell

  As you well know, there is an issue with LPARs that are hanging on machines that have the latest Technology Refreshes applied to IBM i 7.3 and IBM i 7.4 in cases where the Hardware Management Console (HMC) is not managing the partitions. The details of the issue with the Technology Refreshes are outlined in APAR MA48101, and what it means is that a guest partition created with Virtual Partition Manager (VPM) inside SST or Integrated Virtualization Manager (IVM) will hang on IPL after the apply of the TRs. This gets real elaborate, so we strongly suggest you review …

• IBM i PTF Guide, Volume 21, Numbers 51 And 52

  January 6, 2020 Doug Bidwell

  The PTFs keep rolling even through the holidays, so this is our time to get caught up with the last two weeks of patches in 2019 as the new year is beginning.

  In PTF Number 51, we dug a little deeper into the issue we found out about just as The Four Hundred was going on hiatus where LPARs are hanging on machines that have the latest Technology Refreshes applied to IBM i 7.3 and IBM i 7.4 in cases where the Hardware Management Console (HMC) is not managing the partitions.

  The details of the issue with the Technology Refreshes …

• Important: Some LPARs Hang With New TRs – IBM i PTF Guide, Volume 21, Number 50

  December 16, 2019 Doug Bidwell

  Listen up, folks. This one is serious. A few weeks ago, there were some bad patches on the Db2 for i database for IBM i 7.3, as we detailed here, and as last week was coming to a close, we found out that LPARs are hanging on machines that have the latest Technology Refreshes applied to IBM i 7.3 and IBM i 7.4 in cases where the Hardware Management Console (HMC) is not managing the partitions.

  The details of the issue with the Technology Refreshes are outlined in APAR MA48101, which is essentially a bug report that warns …

• IBM i TRs Bring Database Enhancements, Too

  October 30, 2019 Alex Woodie

  The heart of the IBM i server is its database, so it’s natural that we would see some enhancements to Db2 for i with delivery of IBM i 7.4 Technology Refresh 1 and 7.3 TR 7 next month. The new features may not be earth-shaking, but they deliver some useful functionality nonetheless.

  Let’s start with some foundational changes to the database itself, including the way that database engineers architect the tables that store information in the database. With 7.4 TR1, IBM i shops can now add a new child table to the database without having an exclusive lock on the …

• How The Latest TRs Bolster HA/DR And Security

  October 28, 2019 Alex Woodie

  High availability, disaster recovery, and security are more important than ever, as enterprises look for ways to eliminate risks to their operations, applications, and data. To that end, it’s not surprising that IBM bolstered the HA/DR and security capabilities in IBM i with the latest Technology Refreshes that are slated to begin shipping November 15.

  Let’s start with the new HA features in Db2 Mirror for IBM i, the new business continuity offering that implements an active-active database cluster atop two unique IBM i logical partitions. Db2 Mirror, you’ll remember, was delivered with IBM i version 7.4, so it’s …

• An 11-Core Power9 Makes The Rounds, And Other Hardware Enhancements

  October 14, 2019 Timothy Prickett Morgan

  Those of us who go way back in the IBM midrange are used to rhythm in hardware announcements. In the early days, there were several announcements per year as new processors were rolled out across the product line and new peripherals for various kinds of storage and networking were rolled out. The pace was brisk back in the day, with nearly annual processor upgrades and associated updates to systems.

  These days, systems are really updated every three years or so, but still, there is the vestigial spring/fall announcement cadence when Big Blue now does Technology Refreshes for the IBM i …

• The Transition To RHEL 8 Begins On Power Systems

  June 10, 2019 Timothy Prickett Morgan

  If it is not already obvious to you, Red Hat Enterprise Linux is going to be the default and preferred variant of the Linux operating system that will be available on IBM’s Power Systems and System z servers at some point in the not-too-distant future when Big Blue’s $34 billion acquisition of the commercial Linux distributor closes.

  As we pointed out last fall when the deal was announced, we don’t know precisely how IBM will rectify some of the overlaps between the two product lines after the deal closes. What will IBM will do with the WebSphere and JBoss Web …

• 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 …

• IBM i 7.4 Rolled Out, And IBM i 7.3 Tech Refresh Rolled Up

  April 24, 2019 Timothy Prickett Morgan

  Every couple of years, we get a new release of the IBM i operating system from Big Blue, and it has been quite a number of years since we have seen a new version of the platform. But that’s alright, since IBM has its Technology Refresh mechanism for adding support for new hardware and for adding significant new software function to the platform without breaking release-level compatibility and therefore requiring customers to requalify their applications, or worse yet, be forced to port their applications to an updated operating system.

  This new Technology Refresh approach has been a very good thing, …

• An IBM i Year In Review

  December 10, 2018 Alex Woodie

  Another year is just about wrapped up for us here at IT Jungle. That means it’s time to ease off the news pedal just a tad and enter into a retrospective mood, with the hope of gaining some perspective on where we’ve been in 2018 and perhaps how we’ll start off 2019.

  It all started off rather poorly, way back in. . .

  January

  . . . when the big news was about Spectre and Meltdown, the two vulnerabilities that brought everybody rudely back to the real world following the New Year’s celebration. Nearly all types of processors, including …
