A certified configuration is a configuration that passed all the relevant test cases. The list of the certified configurations is described inside the file TestLog that's distributed along with LIXA tarball.

A tested configuration is a configuration that was tested in the past and should reasonably work with similar configurations: tested configurations are proposed in Chapter 5, Developing C Application Programs using TX (Transaction Demarcation) interface. They can be used as a starting point for non trivial configurations with one or more commercial Resource Managers.
