A couple of months ago, IBM announced enhancements to its data replication in support of DB2 v10 for UNIX and Windows.  This month, IBM released an update to its Q Replication Dashboard that supports those enhancements and much more.  In fact, most the Dashboard's enhancements can be used with Q Replication for DB2 z/OS, too.  This post takes a quick look at…

Along with today's announcement about the new version of DB2 and InfoSphere Warehouse, IBM also announced an updated release of …

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…

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…

For those of you who weren't at IOD this year, you may be interested to know that some of the presentations are now available on ibm.com.  The one about active-active data warehousing by Dwaine Snow, Linda Snow, and Enzo Cialini, all of IBM, is a good read that doesn't require you have a presenter handy.  It's pdf format can can be viewed or downloaded from the following link:…

Last week, smarterquestions.org had a very good post comparing two new database offerings for SMB - the IBM Smart Analytics System 5710 and the Oracle Database Appliance (ODA).  Naturally, the first thing I looked for was anything comparing options for…

DB2 LUW partitioned databases haven't been called DPF, the Database Partitioning Feature, since 2007.  However, a lot of people still use the term.  That's not a bad thing, but they tend to search…

   Frequently Asked Questions

Today, IBM announced that it's packaging all of its relational database replication technologies into a single product called IBM InfoSphere Data Replication (IIDR).  Naturally, people are bound to have questions, so I'm going to cover what I…

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…

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…

IBM has a new availability solution, GDPS active-active continuous availability (GDPS/A-A), that offers an unlimited distance between data centers, cross-site workload monitoring, automated workload balancing, and recovery time objectives measured in seconds.  I have a few highlights here.  Full details can be found in…

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." :)

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…
