Abstract:
1. A computer system, comprising: a plurality of processing units, each having a processor; a load distribution apparatus that assigns a processing request from a client terminal to one of said plurality of processing units; and a handover data management computer that holds and manages handover data that includes handover data identification information including user identification information, wherein said handover data is used to continuously carry out a processing of said processing request and said user identification information includes a user identifier received from said client terminal when a client of said client terminal logged into said computer system, and wherein, when a connection between said client terminal and said load distribution apparatus is disconnected when a fault occurs in said one of said plurality of processing units to which a first processing request was assigned, another one of said plurality of processing units to which a second processing request is assigned by said load distribution apparatus obtains, by using user identifier included in said user identification information in said second processing request, said handover data to carry out said processing of said first processing request, and generates handover data for said second processing request carried out by said another one of said processing units to transmit generated handover data to said handover data management computer, and further generates and transmits response data for said client terminal.
