• Does Db2 Mirror Kill The Market for Third Party HA?

  May 6, 2019 Alex Woodie

  IBM launched Db2 Mirror for i two weeks ago to great acclaim, as the clustering technology puts IBM i on par with how most other major systems provide continuous availability. But will Db2 Mirror destroy the platform’s heritage of high availability solutions? IT Jungle asked IBM and the biggest providers of logical replication solutions, and the answer is no. Here’s why.

  The first thing to understand about Db2 Mirror is that, at heart, it’s a database clustering technology. IBM figured out a way to make a single instance of Db2 for i run on two separate systems, in an active-active …

  May 6, 2019 Timothy Prickett Morgan

  We did our initial coverage of the new Db2 Mirror for the IBM i operating system’s integrated database two weeks ago, and now it is time to dig in a little deeper. Elsewhere in this week’s issue of The Four Hundred, we have gotten feedback from the suppliers of high availability clustering and disaster recovery software for the IBM i platform as to how Db2 Mirror compete with as well as complements their wares. And in this story, we will be digging a little deeper into Db2 Mirror itself.

  As we explained, Db2 Mirror creates an active-active database …

• How IBM i 7.4 Improves Security

  The unveiling of Db2 Mirror may have gotten the lion’s share of attention with last week’s introduction of IBM i enhancements. But IBM has also given its customer base some significant security upgrades with the new releases of IBM i, including enhancements to the Authority Collection and support for the latest over-the-wire encryption protocol.

  “Our big things are around those two main themes – availability as well as security,” says Alison Butterill, IBM i product offering manager at IBM. “Those are the two main themes. But we have lots of things across the board.”

  IBM gave customers significant new user-focused …

• IBM Brings Active-Active Mirroring Into Db2 For i Database

  April 24, 2019 Timothy Prickett Morgan

  As a platform that is approaching 40 years of deployment within enterprises that can’t afford downtime with their mission critical systems – that’s counting the System/38 as well as the AS/400 and its follow-ons as part of the same continuum – it is no surprise at all that IBM midrange systems running RPG and COBOL had some of the most sophisticated – and perhaps the only application-centric – clustering software ever developed.

  Concurrent with the launch of IBM i 7.4 this week, Big Blue is rolling out a new kind of database clustering, which is called Db2 Mirror, that is …

• 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, …
