Abstract

A method and apparatus for comparing two computing platforms installed with instances of an application, a portal or another computerized unit, wherein one computerized unit malfunctions when executed by the corresponding computing platform.

The method and apparatus query the two computing platforms and the two instances for a multiplicity of values associated with a multiplicity of parameters that may influence the functionality, compare the parameter values and report the differences to a user, in order to enable the user to locate the root cause of the problem. The parameters may relate to the instances as well as to the computing platforms and their environment.

The parameter retrieval and comparison can be performed by the apparatus, or by components of the instances for handling proprietary data types.

component installation order;

deployed component or deployment order;

connectivity;

an internet parameter;

a configuration;

a user setting; and

an authorization.

15. The apparatus of claim 1 wherein the apparatus is executed by the first computing platform or the second computing platform.

16. The apparatus of claim 1 wherein the apparatus is executed by a third computing platform.

17. The apparatus of claim 1 further comprising a component for issuing an at least one recommendation to the user.

18. The apparatus of claim 17 further comprising a component for automatically performing the at least one recommendation.

19. In a computer network comprising a first computing platform executing or having installed thereon a first instance of a computerized unit and a second computing platform executing or having installed thereon a second instance of a computerized unit, each providing an outcome, and wherein the outcome of the first instance on the first computer platform differs from the outcome of the second instance on the second computer platform, a method for retrieving the differences between the first computing platform and first instance, and the second computing platform and second instance, the method comprising:
