PROBLEM TO BE SOLVED: To provide an information processor, the control method of the information processing system and the control program of the information processing system for suppressing a rise in an access to a database when the number of nodes which perform load distribution is changed.SOLUTION: There are several cache nodes 201 to 203. There are several storage parts 401 to 410, and the storage parts are assigned to each of the cache nodes 201 to 203. A management part 100 receives an access request, and instructs the cache nodes 201 to 203 as access destinations to perform processing based on the received access request. When any of the cache nodes 201 to 203 breaks down, a control part 301 switches the assignment of the storage parts 401 to 410 assigned to any of the cache nodes 201 to 203 which has broken down to any of the cache nodes 201 to 203 other than any of the cache nodes 201 to 203 which has broken down. |
