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:…

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." :)

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. …

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…

2009's 10 Most Popular Replication Features for DB2

While preparing for what's likely to be coming my way in 2010, I thought about the topics I spent the most time on in 2009. I eventually wound up with a list of 10 that I felt were the most popular with the sales teams and customers I worked with. I thought I had a pretty good list :) so I emailed it to my collegues to get their impression. Naturally, everyone had at least a slightly different list and, when there was overlap, everyone wanted a slightly different order. Go… Continue
