摘要： PROBLEM TO BE SOLVED: To quickly take countermeasures to the rapid increase of a memory leak quantity due to computer virus or the like. SOLUTION: When a memory leak monitoring timing comes (a step 10), the mean value of memory usage in the present period is calculated (a step 11), and the mean value in the past period is subtracted from the mean value in the present period, and the value is defined as the increment of the memory leak quantity (a step 12). Then, the memory leak increment is divided by a time difference between the present period and the past period, and the memory leak increase rate is calculated (a step 13), and when the memory leak increase rate exceeds an upper increase rate (steps 16, 18), a request for countermeasures to the memory leak is outputted.

摘要： PROBLEM TO BE SOLVED: To improve security of data against the theft of a node device and unauthorized access in a computer system comprising a client, the node device and a storage device. SOLUTION: In the computer system capable of transferring data through the node device between the client and storage device, cache in the node device is controlled in the following method. In the first control, the attribute of cache propriety is given on data stored in the storage device, and the node device carries out relay to the client without performing cache on cache-disabled data. In the second control, the node device enciphers data in caching to a disk. In the third control, the cache-disabled data are directly transmitted and received without passing through the node device. With this control, cache to the node device can be limited to ensure security. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To avoid the possibility that a restarted OS fails due to the same factor again by detecting the failure of an OS in operation, and calculating an OS control parameter as the solution of the factor of the failure. SOLUTION: A computer system having a means for restarting the same OS or the same type of OS when the execution of an OS in system operation can not be continued is provided with: a means for detecting the failure incapable of the continuity of the operation by a means for analyzing its own load status or failure and by a failure monitoring means; and a means for specifying a kernel control parameter item and value for solving or avoiding the circumstances. When the specified parameter includes a static control parameter, the specified parameter is designated, and the same OS or the same type of OS is restarted. When the specified parameter is a dynamic parameter, the restart of the OS is not operated, and it is applied to the OS in operation. Also, when the OS is restarted according to the instruction of a manager, the optimization parameter specified so far is applied to restart the OS. COPYRIGHT: (C)2006,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To improve data readout speed from a disk device in a computer system capable of transferring data through a node device 200 between a client 100 and a storage device 300. SOLUTION: A common volume PDc and unique volumes PDa, PDb are defined on a disk device of a storage device 300. Data common to each client are stored in the common volume, and data unique for every client are stored in the unique volume. When each client requests readout of data to virtual volumes VDa, VDb, the storage device reads corresponding data out of the common volume or unique volume. Consequently, even if access concentration from a plurality of clients is occurred, a lowering of readout speed can be suppressed since data are mainly read out of the common volume.
