You may have seen  the recent video here on ChannelDB2 that introduces auditing of DB2 changed data.  If you're interested in giving it a quick try, it's easy set up a simple configuration and see what you get. That's what I'm going to show you how to do in this post.  It should take about 5-10 minutes.  We'll use DB2's SQL Replication.  It's provided with all editions of DB2 and InfoSphere Warehouse…

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…

As with I did for last year's IOD, I'm providing a consolidated list of sessions for Replication and Federation at this year's IOD as well.  These sessions should be of interest to anyone with data integration needs.  Session descriptions can be found in the on-line IOD agenda for registered participants. Hope…

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…

Last month IBM announced a new Data Replication product that bundles its CDC, Q, and SQL Replication technologies.  IBM's intent is to provide all replication enhancements through this new product.  To go along with that direction, IBM just announced an update to the CDC technology in Data Replication.  The new level is Data Replication 10.1.1. I'll list a few highlights in this…

   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…

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…

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." :)

You have your…

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…
