HDR, which *is* a different product entirely, can be viewed as a sub-set of ER. It provides for complete duplication of an entire instance in two places, the goal of which is failover in the event of a "down" server. > I would be interested in any doc's or url's that are good references to >the specs on these products. Sadly, Informix's web page is not all it could be in this area. (Be sure to tell the "feedback" people what you think of the pages and their information content when you visit the web site.) The best place to learn about replication is to sign up for a class at an Informix training center. There is a whole class on ER, with a very informative training manual. Even more, you can run the actual product to your heart's content.
