This month, IBM released an update to the Q Replication Dashboard.  The most significant enhancement is the addition of a simplified user interface that's designed for web browsers in small touch-screen devices.  I've tried it on both an iPhone 4S running iOS 5.0.1 and a Google…

Using Q Replication with DB2's HADR

About two years ago, I posted a video showing how to use SQL Replication with HADR.  Lately, I've gotten a bunch of requests to do something similar for Q Replication and HADR.  The good news is that I don't have to :)  there's now a white paper called…

Building Time-Delayed Targets with Data Replication

 

Most replication products talk a lot about how great high-speed data replication is.  Naturally, I agree :)  It's great. However, if something ever corrupts your source data, you'll likely see an ugly side of speed - your target gets all the source's corrupt data with sub-second latency.  What a pain.  You have no time to prevent the mirrored corruption. That might leave both source and target unusable. And that's especially frustrating if your target is supposed to be a…

Why Data Replication and Federation Are a Good Match

Years ago, IBM had a product called Information Integrator (II).  It was IBM's first attempt at a data integration platform.  While II is no longer around, one thing it got right was the approach of solving customer problems through a combination of data replication and data…

New developerWorks Article About DB2 AESE's Federation and Q Replication

I get a lot of questions about what's included in DB2 Advance ESE where data federation (virtualization) and replication technologies are concerned.  Some of them are simple licensing questions about what you get for no extra charge.  However, many more are about basic functionality. developerWorks helps out in both cases.  For the questions about function, there's…

Should You Switch from IBM's SQL Replication to Q Replication?

SQL Replication is a data replication technology that's been used with great success in many shops for over 20 years. Yet, IBM also provides the Q Replication technology that has developed an excellent reputation for high performance, continuous availability, and zero-downtime database migration. Naturally, that leads SQL Replication users to ask if they should switch from SQL to Q. The answer, like the answer to many other questions, is... "it depends." :)

 

You have your…

pureScale, Q Replication, and Active-Active Databases

IBM has an excellent new white paper on developerWorks about using Q Replication for active-active databases with DB2 pureScale.  It covers everything from basic terminology and set up to why WebSphere MQ adds value to active-active replication.  I like this paper for two reasons.  First, it's the most complete documentation IBM has for using Q Replication with DB2 puresScale. …

Using Data Federation with solidDB

I hadn't actually thought of using federation with an in-memory database, but someone asked and I decided to give it a try. Turns out it's very easy. I also discovered two things that can be useful to a DB2 person like me who's just getting started with solidDB. I'll use this post to talk about those and show you how you to try solidDB federation yourself. Of course, if you've never done anything with IBM's data…

2010's 10 Most Popular Data Replication Topics for DB2

These are the ten topics that I felt were the most popular with the sales teams and customers I worked with in 2010. As with last year's list, this year's based solely on my own experience. No way I'm going to try to reconcile my colleagues' opinions and come up with a composite list :)  There are just too many opinions around for that.  I'll stick with mine, start at the top, and work…

Disaster Recovery, High Availability, and Continuous Availability - What's the Difference?

Last month I posted a video that gave a brief overview of how data replication is used for continuous availability. I then got ask why I used the term continuous availability instead of high availability or disaster recovery. "What's the difference?" Well, while these solutions have a lot of overlap and can usually be built from some of the same components, they can have different objectives. Different objects can…
