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.

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.

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.
