Provided is a distributed processing system in which migration evaluation is performed based on performance information, statistical information of each process of an application, and the number of non-completed processes of each process of an application for an application server in which an old application is being operated, a migration target server group is decided so that migration is completed in a shortest period of time, and migration to a new application is performed in a stepwise manner.

Distributed processing system for use in application migration

A compiling method for reading, by a computer comprising a processor and a memory, a source file therein and outputting an executable binary file, the compiling method including: a first step of receiving, by the computer, an interface file including a process and a module constructing a business process, input/output information of data of the business process being defined in the interface file, operation information for data set to be used in the business process being defined in the interface file; a second step of validating, by the computer, the operation information for the data set defined in the interface file; a third step of inhibiting, by the computer, generation of the executable binary file when a validation result is invalid; and a fourth step of generating, by the computer, the executable binary file from a source file containing the interface file when the validation result is valid.
