摘要： A computer system including a plurality of shared resources to be used exclusively by a plurality of tasks. Upon occurrence of an interrupt, execution of the task running at that time is suspended to allow the interrupt task to be executed. After execution of the interrupt task, one of the tasks remaining in the execution waiting state is selected for execution. A method of scheduling tasks with priority to the task locking a shared resource includes the steps of registering a task identifier of a task being executed upon locking of the task to a resource, invalidating the registered identifier of the task when that task releases the shared resource from the locked state, deciding whether or not a valid task identifier representing the task which was running by locking the shared resource is registered when a task to be executed next is to be selected after execution of the interrupt task, and selecting the task designated by the task identifier, if registered, to thereby select the task as the one to be executed with priority.

摘要： The present invention performs appropriate archive management using a device that allows random access. An archive managing part 1B reads out files stored in an on-line volume 5A at a timing determined by the respective file type, and stores these files in a specified volume among archive volumes 5B1 and 5B2. A retention term is designated for each set of file data, and respective retention terms are also set for the respective volumes 5B1 and 5B2. The file data is stored in a volume having a retention term that matches the retention term of the file data. The respective volumes 5B1 and 5B2 are set in a device that allows random access such as a hard disk or the like. The areas in which data is written into the respective volumes 5B1 and 5B2 are managed as write prohibited areas by means of pointers P. As a result, the respective volumes 5B1 and 5B2 are used as a so-called WORM device.

摘要： A disk subsystem provided with a cache has a capability of executing writing of data of discontinuous dirty blocks on a cache memory into a disk and reading of data of discontinuous empty blocks on the cache memory through the effect of just one DMA transfer. When the dirty data discontinuously ranged on a cache segment is written on the disk, the microprocessor provides a bit-map to a harddisk controller (HDC) as control information for data transfer. If an i-th bit of the bit-map is "1", the HDC operates to write the i-th block data sent from a direct memory access controller (DMAC) onto the corresponding sector of the disk. If the i-th bit is "0", the microprocessor serves to stop the write of the data and control a read/write head to wait until it passes the corresponding sector.

摘要： A disk array apparatus, which has redundant data arranged in a distributing layout by record includes apparatus for speeding up redundant data updating processing during later updating, apparatus and a read head and write head securely mounted on a single actuator. In operation, old parity data is read out by the read head and then is used to generate new, updated parity data. The updated parity data is written into the record where the old parity data was held within one turn of the disk after the old parity data has been read out.

摘要： Data in a storage area to be returned from among storage areas of a storage system is deleted without fail, thereby ensuring data security.When a user's storage-on-demand management program 24 is activated in response to a return request from user A's console terminal 18, the return request is transferred via a communication network 14 to a server 16, and a provider's storage on-demand management program 30 makes a request to a storage management program 32 for volume initialization and data deletion. After the storage management program 32 issues a volume initialization command after receiving the above request, a control program 76 is activated to initialize the designated volume. Subsequently, the user A's volume access right is deleted by the processing executed by the provider's storage-on-demand management program 30, and it is reported to the console terminal 18 that the volume initialization and the volume separation have been conducted.
