Abstract: An information processing system comprising a memory, and a processor coupled to the memory and configured to receive requests from a plurality of client apparatuses, store, in the memory, information about sessions established to communicate with the plurality of client apparatuses, store, in the memory, a request in response to which processing has not yet been started, the request being one of the requests received from the plurality of client apparatuses, detect a session during which a predetermined time-out time has elapsed in a state in which processing demanded by a request corresponding to the session is not being executed, the session being one of the sessions, information about the sessions being stored in the memory, and suppress, when a request received from a client apparatus corresponding to the detected session is stored in the memory, invalidation of the session due to an elapse of the time-out time.

Abstract: A processing method includes: collecting processing information indicating a processing state of an application executed by an information processing device and operational information indicating operational states of processing elements that are identified on the basis of configuration information stored in a storage unit and are involved in the execution of the application; determining whether or not there is a correlation between the processing state and an operational state of each of the processing elements on the basis of the processing information and the operational information when a delay of a process of the application is detected on the basis of the processing information; and extracting, from among the processing elements, a processing element of which an operational state has a correlation with the processing state on the basis of the determination.

Abstract: A data search method includes: identifying data and a key value associated with the data based on a search request issued to a first database stored in a first storage in which data included in a column of the first database is stored in association with a key value that is associated, in the first database, with the data; and searching for a row associated with the identified key value from a second storage in which the key value in the first database is stored in association with the row that is associated, in the first database, with the key value.
