摘要： A computer capable of managing reference relationships between data executes access of first and second storage regions in which stored data can be altered and a third storage region in which stored data cannot be altered. The computer sets specification data in the first storage region for accessing data stored in the second and third storage regions, and shifts data having a reference relationship with the specification data from among the data stored in the third storage region to the second storage region. If the accessing occurs while the shifting is being carried out and the data has already been shifted to the second storage region, the reference information for the specification data is amended to the shifted location of the data, and all of the references to data in the third storage region that are referenced by the specification data are amended, thereby releasing the third storage region.

摘要： Memory management by garbage collection involves a memory area that is allocated in a computer. Data is created in the memory area in accordance with a program executed by a processor of the computer, and it is checked whether or not data necessary to execute the program exists in the memory area to be released, in response to an explicit instruction to release the memory area. As a result of the check, if data necessary to execute the program does not exist in the memory area, the memory area is released. As a result of the check, if data necessary to execute the program exists in the memory area, the data is moved to a memory area different from the memory area to be released.

摘要： With regard to a plurality of data stored in a memory, relationship of data is grasped twice after a time interval therebetween. Next, increased data C1, E2, E3 which are not present in data of a first time are extracted from data of a second time, and weights “1”, “2”, “2” in accordance with data sizes are attached to the increased data. Next, the weights are successively propagated from a lower order data of a destination of reference to a higher order data of a source of reference successively. When there are a plurality of lower order data E2, E3 for a higher order D0, a weight constituted by adding the weights “2”, “2” of the plurality of lower data E2, E3 is made to be a weight “4” of the higher order data D0, and the weights of the respective data represent leak scores which causes memory leak.

摘要： To reduce labor required in investigating on a source of memory leaks with regard to the memory leaks generated in executing a program using a language which does not explicitly indicate release of data region. With regard to a plurality of data stored in a memory, relationship of data is grasped twice after an time interval therebetween. Next, increased data C1, E2, E3 which are not present in data of a first time are extracted from data of a second time, and weights “1”, “2”, “2” in accordance with data sizes are attached to the increased data. Next, the weights are successively propagated from a lower order data of a destination of reference to a higher order data of a source of reference successively. At this occasion, when there are a plurality of lower order data E2, E3 for a higher order D0, a weight constituted by adding the weights “2”, “2” of the plurality of lower data E2, E3 is made to be a weight “4” of the higher order data D0, and the weights of the respective data represent leak scores which causes memory leak.

摘要： A computer includes a storage region in which an object generated by executing a program is disposed, and a control unit that performs execution of the program and releasing of the storage region. The control unit updates time information using garbage collection, a capacity of objects in a memory, or similar as a trigger, acquires information of a program generating an object and time information at the time of generation of the object which are recorded in a recording device so as to be correlated with each other when the object is generated. The control unit further detects an object which is unnecessary to execute a subsequent program and acquires the time information, and records a difference between the time information at the time of the generation and at the time of the detection in the recording device so as to be correlated with the information of the program.
