There is provided a technique of enabling to easily identify the association between process results in a plurality of components which are executed in association with an RPC. An information processing system in which an application of a first component performs an RPC for a functional function of a second component, the system comprises: a stub of the first component configured to receive the RPC and transmit an RPC message to the second component; and a skeleton of the second component configured to receive the RPC message from the stub and control execution of a predetermined function. The stub generates an RPC message having a header in which a sequence identifier acquired from the first management unit is embedded, and transmits the generated RPC message, and the skeleton extracts a sequence identifier from the header of the received RPC message.
