Abstract: An information processing apparatus includes a rewriting unit and an execution unit. The rewriting unit rewrites a first instruction described at a trace point in a function defined in a program to a second instruction which gives instructions to execute a trace code, and stores the first instruction in a storage unit. The execution unit executes the trace code on the basis of the second instruction at the time of execution at the trace point in the function. If a third instruction which calls the function is included in the trace code, the execution unit replaces, at the time of executing the third instruction, the second instruction at the trace point in the function with the first instruction stored in the storage unit, and performs the function.

Abstract: A non-transitory computer-readable recording medium stores a memory management program that causes a computer to execute a process. The process includes detecting writing into a memory; and saving, in association with each other in a predetermined storage area, data before the writing which is stored in a data area of a write destination of the detected writing, and context information of a processor at a time of detecting the writing into the memory.

Abstract: An information processing device includes a processor that performs a process. The process includes: when the information stored in the first storage unit is stored in the second storage unit, storing the storing completion information corresponding to the stored information in the storing completion information storing unit; detecting a failure in the information processing device; performing a restart process on the information processing device using a region in which the stored information has been stored in the first storage unit on the basis of the storing completion information when the failure is detected; and discriminating information that has not been stored in the second storage unit from among the pieces of information stored in the first storage unit on the basis of the storing completion information when the failure is detected, and storing the discriminated information in the second storage unit.

Abstract: In an information processing system, a management apparatus reads all data from a storage device connected to an information processing apparatus, and stores the data as one image file in a backup storage device. A virus detection apparatus performs a virus detection process on the image file stored in the backup storage device in response to a request from the management apparatus, and if a computer virus is detected, performs a virus removal process on the image file. When the virus removal process is completed, the management apparatus reads and writes the image file from the backup storage device back to the storage device.

Abstract: A high reliability system in which a plurality of apparatuses each having a variable function unit and a fixed function unit are mutually connected through an internal network. Pairs of apparatuses are constructed and spare apparatuses are allocated, thereby providing redundancy. Each apparatus has a service processing unit which executes the software for providing a peculiar service to every apparatus pair, a synchronization processing unit which synchronizes the services between the apparatus pair, a fault detecting unit which detects a fault of the pair partner apparatus, and a fault processing unit which, issues a pair request to the network and reconstructs an apparatus pair together with the apparatus to which the pair application has been made. The redundancy recovery after the exchange of the failed apparatus is executed automatically, thereby shortening a time in a non-redundant state.

Abstract: A high reliability system in which a plurality of apparatuses each having a variable function unit whose function is changed by replacement of software and a fixed function unit according to hardware or fixed software are mutually connected through an internal network, pairs are constructed with respect to the plurality of apparatuses, and spare apparatuses are allocated, thereby giving redundancy, and those apparatuses are connected to an external network.
