Abstract: A technique for managing storage of a data object in a storage device involves receiving the data object (A) to store in the storage device, where the data object has an indicator bit pattern (P). Successive compression data transformations are applied to data object A to obtain respective corresponding compressed data objects, and one of these compressed data objects is selected, such that the selected compressed data object (C) has the shortest length with respect to the remaining compressed data objects. Compression information (I) is then associated with the compression data transformation used to generate data object C, and a threshold value T is calculated at least partly from the length of compression information I. If length (C)+T.gtoreq.length (A), then the indicator bit pattern of data object A is reset and the data object A is written to the storage device. If length (C)+T

Abstract: A method and system for allocating storage space from storage devices within a computer system. The storage devices are grouped into respective homogeneous sets in which identical storage devices are included in the same homogeneous set. In accordance with the method and system, following receipt of an allocation request for storage space one or more stored response values are checked, the response values associated with at least one homogeneous set. The stored value or values represent the average response time of storage devices within the set. The homogenous set with the lowest average response time is selected. One or more stored allocation values are then checked that are associated with at least one storage device within the selected homogeneous set. The stored allocation value or values represent the current allocations of the associated storage device. The storage device is selected with the lowest current allocations and the storage space is allocated in the first available location on the selected device.

Abstract: Computing capacity of a computing environment can be managed by controlling it associated processing capacity based on a target (or desired) capacity. In addition, fine-grained control over the processing capacity can be exercised. For example, a computing system can change the processing capacity (e.g., processing rate) of at least one processor operating based on a target capacity. The computing system may also be operable to change the processing capacity based on a measured processing capacity (e.g., a measured average of various processing rates of a processor taken over a period of time when a processor may have been operating at different processing rates over that period). By way of example, the processing rate of a processor can be switched between 1/8 and 2/8 of a maximum processing rate to achieve virtually any effective processing rates between them.

Abstract: A computer-implemented apparatus, method, and article of manufacture manage a plurality of database systems and perform data maintenance tasks in a data warehouse system. A domain includes a plurality of database systems. A virtual regulator manages the domain, detects a request to invoke a data maintenance task on a first system in the domain, routes the data maintenance task, for execution, to a second system in the domain, and applies results from the data maintenance task (executed by the second system) to the first system.

Abstract: Optimizing the execution of a query in a multi-database system includes identifying a region within a table, the table being referenced in the query. The region is stored on data-storage devices on first and second system databases in the multi-database system. A first access plan for the query is developed, the first access plan comprising accessing the version of the region stored on the first system database. A second access plan for the query is developed, the second access plan comprising accessing the version of the region stored on the second system database. A selection is made between the first access plan and the second access plan to execute the query. The query is executed using the selected access plan to produce a result.

Abstract: A method and system for allocating storage space on a storage device to a requesting entity. The storage device includes a set of extents. An allocation map is maintained in computer memory. The allocation map has a plurality of map blocks, the map blocks each having a plurality of map entries. The map entries include respective logical extent identifiers, physical extent information and obsolete indicators. An invalid extent logical identifier represents a free extent and a valid extent identifier represents a prior allocated extent. An obsolete indicator marks a map entry as either current or obsolete. In one technique an extent allocation request is received from the requesting entity. A first map block is selected having a first map entry marked as obsolete. A second map block is selected having a second map entry not marked as obsolete. Physical extent information is copied from the second map entry to the first map entry. The logical extent identifier is assigned to the first map entry. The first map entry is marked as current and the second map entry is marked as obsolete. The storage allocation system includes a disk storage device having a set of extents. A requesting entity is configured to request allocation of one of the extents. An allocation map is maintained in computer memory. An allocator is configured to allocate one of the extents on the disk device to the requesting entity.

Abstract: A non-volatile storage device is used to track status changes in one or more items, where it is less costly to set bits in the non-volatile storage device than to reset bits. For each of the items to be tracked, at least two bits of storage space are allocated in the non-volatile storage device. One of the bits is set when the item changes status, and another of the bits is set when the item changes status again.
