Abstract: An information processing apparatus includes a check data applicator, a count-up determiner, and a patch data applicator. When there is a modified part in a computer program under operation and the modified part has been executed, the check data applicator applies check data incorporating processing of counting the number of times the modified part has been executed to the program under operation. The count-up determiner determines if the count indicating the number of times the modified part has been executed is counted up at a predetermined timing as a result that the check data has been applied. When the count has been determined to be counted up, the patch data applicator replaces the check data including the modified part determined to be counted up with a post-modification program including the modified part having been modified. The configuration described above enables appropriate determination whether the post-modification program is to be applied.

Abstract: A candidate-patch selecting apparatus includes a detector configured to detect a failure of a computer; an obtaining unit configured to obtain record information for the computer, recorded at the time when the failure detected by the detector occurred; an extractor configured to extract from the record information obtained by the obtaining unit, information identifying the failure; an identifying unit configured to identify, based on a database that stores therein patches and respective selection conditions, a patch for which selection conditions are satisfied by the extracted information identifying the failure; and an output unit configured to output an identification result acquired by the identifying unit.

Abstract: A CPU in a computer includes a control information management table for storing information about whether an error has occurred in a control unit in the computer or in a control unit in a communications card. When an error occurs in any of the control units, the occurrence of the error is recorded in the control information management table, and an error message is transmitted by the monitor to an operator. When a dump collection command is issued by the operator in response to the error message, the monitor specifies the CPU in the computer or the communications card which operates the control unit where the error has occurred, by referring to the control information management table, and collects only the dump information corresponding to the control unit.
