PROBLEM TO BE SOLVED: To solve a problem that wasted processing time is significantly generated when an application is migrated in a distributed processing system, which makes the degenerate time of the system longer.SOLUTION: In order to solve the problem, there is provided a distributed processing system designed to perform evaluation of migration based on performance information on an application server during operation of an old application, and statistic information and the number of unfinished processing for each processing of an application, determine a migration target server group which allows migration to be finished in the shortest amount of time, and gradually migrate the old application to a new application. |
