Paul Zikopoulos and Chris Eaton - Availability with Clicks of a Button Using DB2’s HADR

If everyone wants it, why is high availability becoming harder to achieve in today’s databases? It seems that more and more availability errors are caused by human error. That’s why IBM came up with HADR, an architecture for high availability and zero transaction loss, but in an environment that is very simple to set up (and, hopefully, less prone to human error). In this podcast discussion, Chris Eaton and Paul Zikopoulos talk about HADR, in which two servers are kept completely in sync at the database level, providing a redundant copy of data in case of any problems with one server. They share insights into the design process of HADR, and answer questions including what types of operation don’t get sent to HADR, how can you read of an HADR database, and more. And, for more detail about HADR, you can read the article, Availability with Clicks of a Button Using DB2’s HADR.
