Abstract: A non-transitory computer-readable recording medium stores an incompatibility detection program causing a computer to execute a process including: identifying a type of a setting file of an application that operates in a first application execution environment; and detecting an incompatibility that occurs in the setting file of which the type is identified, by applying merely an incompatibility detection rule corresponding to the identified type of the setting file among one or more incompatibility detection rules in each of which information on an incompatibility detection pattern for determining that the setting file includes an incompatibility that occurs along with migration from the first application execution environment to a second application execution environment different from the first application execution environment and information on the type of the setting file in which the incompatibility occurs are associated with each other.

Abstract: An information processing apparatus including: a processor configured to: receive halted virtual machine information that identifies a first virtual machine to be halted in a plurality of virtual machines that execute requests each being distributed to one of the plurality of virtual machines, receive, from a second virtual machine, specified session identification that identifies a specified session associated with a second request to be executed by the second virtual machine when the second virtual machine does not hold, specified session information taken over from a first request to the second request, the first request being associated with the specified session and having been executed specified one of the plurality of virtual machines other than the second virtual machine, request, when detecting the specified one of the plurality of the virtual machines is the first virtual machine, transmission of the specified session information held in the first virtual machine.
