摘要: An in use table manager in a computer system uses an in use table to track the use of files, or objects. The in use table is used to determine which objects may need recovery in the event of a system failure. Object addresses are hashed by the in use manager to identify a preferred slot in the table. The slots contain information identifying the object, and indicating the extent of use of the object. The in use manager assigns alternate slots, and dynamically changes the size of the in use table to reduce contention for slots. Several atomic operations on the table ensure integrity of the table, while permitting concurrent use. Portions of the table are bundled into single I/O operations to enhance system performance by minimizing I/O.

摘要: Customized instructions for installation of a device having multiple variable components is described, and are generated by an instruction generator program. A device description file lists a desired set of components for the device. Each of the components is broken down into one or more installation tasks, and the tasks are sequenced in a desired order for installation of the device. Text and graphic modules for inclusion in the instructions are varied based on the physical characteristics of the components, and their interconnection. Scaled line drawings are also generated based on information about each component and its placement in the device.

摘要: The present invention optimizes storage of stream file by dynamically adjusting the size of new extents. In one embodiment, a file system manager collects usage statistics for a plurality of files in a file system. The file system manager uses the usage statistics to create larger extents for frequently used files than for infrequently used files.
