IBM Delivers a Db2 Mirror Update

January 12, 2022 Alex Woodie

IBM updated its Db2 Mirror continuous availability solution last month with support for ObjectConnect, which shrinks the amount of disk space required to copy objects from one IBM i server to another. It also updated the high-speed networking protocols at the heart of the Db2 Mirror solution, which should improve the security of data flowing over networks and makes Db2 Mirror clusters more feasible over longer distances.

IBM has provided ObjectConnect commands on the IBM i server for years as a way to replicate IBM i objects. The software is useful because it improves the efficiency of copy operations by …

PowerHA Updates Focus on Integration and Automation

May 13, 2020 Alex Woodie

Despite the introduction of Db2 Mirror last year, PowerHA remains a critical component ensuring the high availability and disaster recoverability for thousands of IBM i shops around the world. Recent updates, including the delivery of PowerHA version 7.4 in the second half of 2019 and a minor update delivered in March 2020, have focused on bolstering the product’s integration with Db2 Mirror, as well as HyperSwap in the DS8000. Automation, monitoring, and usability have also been improved.

Brian Nordland, the PowerHA technical product manager with HelpSystems (which develops the product on behalf of IBM) recently updated the IBM i …

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 …

Midrange Dynamics Speeds Table Updates In Db2 Mirror Clusters

August 5, 2019 Alex Woodie

With the launch of Db2 Mirror with IBM i 7.4 in June, IBM heralded the age of continuous availability on the midrange platform, bringing IBM i up to par with Windows and Linux platforms. However, while the new software keeps production data in perfect synch, it’s not so great at keeping up with changes to underlying database tables. That’s an area that Midrange Dynamics is addressing with its change management software.

With Db2 Mirror, IBM has essentially extended a single-server database implementation into a clustered database with two active nodes. As soon as a piece of data is created, updated, …

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 …

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 …

Tweaking Systems And Withdrawal Symptoms

March 4, 2019 Timothy Prickett Morgan

A system product line does not always come out finished and complete, all at once, and its retirement from the sales catalog and the field is not always a simple and smooth thing, either. After a certain amount of criticism from its largest customers, Big Blue last year decided that it would get a little bit more orderly about the latter, as machines are withdrawn from marketing and eventually support. As for the former, well, there are always some nips and tucks that are done here and there as parts of the system are tweaked to meet specific customer demands. …
