摘要： A method for moving files between network storages in a virtualized network storage system having multiple network storages and rebalancing the free disk spaces. It periodically judges whether to start rebalancing. Two different conditions are adopted for the determination of start: (a) an imbalance of free disk spaces and the minimum value of the free disk spaces is less than a threshold and (b) an imbalance of free disk spaces and the frequency of accesses to the system is less than a threshold. Rebalancing is performed until the difference in free disk spaces falls below the threshold without exceeding the maximum execution time of rebalancing. If a request to write into a file which is being moved from a client takes place during a file moving step, the movement of the file is aborted and the file is deleted from the destination.

摘要： A virtualizing file system view method for virtualizing one or more network storage devices into a virtualized file system view network storage system wherein destination network storage information of stored files is compactly held regardless of the number of files, and files are separated into one or more file groups and the file groups managed in destination network storage units. Until now, managing network storage unit information in individual files was necessary however the virtualizing file system view method reduces the management information that must be held and efficiently utilizes network storage capacity without holding destination network storage information in individual files. The cost of rewriting information is also lowered during structural changes such as adding or deleting network storage units since storage destination network information can be rewritten in file groups.

摘要： There are provided a heap memory management method that not only improves processing performance of an application program but also reduces a program development cost and a computer system using the same method. A live object copy process in minor collection of generational garbage collection is implemented through a calculate process of object live ratio, a compare process of object live ratio, and a live object copy process. The calculate process of object live ratio calculates a ratio of a size of a memory allocated to live objects of new objects to a size of a memory allocated to a new object during minor collection. The compare process of object live ratio compares a calculated object live ratio with a predetermined threshold. The live object copy process copies a live object directly to an old-generation heap instead of a new-generation heap when the object live ratio exceeds the threshold as a result of comparison. Further, an application programmer provides means for setting the threshold that decides a copy destination of the live object as a runtime parameter of a program and means for holding the set threshold in a memory.
