23.6 High Availability testing

In Chapter 20, Introduction to performance testing, we introduced the concept of High Availability testing in WebSphere Commerce performance testing. Generally, before starting the High Availability testing, having a good understanding of the utilities or solutions that we use to achieve High Availability in WebSphere Commerce site is very important. For example, if we want to use DB2 High Availability and Disaster Recovery (HADR) to achieve High Availability in the WebSphere Commerce database tier, several concepts should be kept in mind:

The general approach to apply High Availability testing on a WebSphere Commerce Web site can be classified as:

The key point here is that High Availability is much more a concept built on the customer's point of view, so that the comparison and judgement according to the result that we got should be assessed and evaluated from the customer's view, which sometimes is the most difficult step in driving the performance test.
