摘要： A method for obtaining parallel instruction execution (PIE) for frequently used programming operations, such as database record compression or expansion, cryptographic encoding/decoding, page moving, etc., for which a hardware-assist may be provided. These functions can be performed in parallel with CPU processing by a PIE processing facility (PIE-PF). The method is hardware/microcode based and uses software control in supervisory mode. The preferred embodiment is controlled by privileged subsystem software under an operating system, and does not use I/O channel oriented off-load processing. When the CPU is interrupted during an incomplete parallel operation by the PIE-PF, it is checkpointed in main storage in a manner accessible to the subsystem. The subsystem (after completing a current CPU operation, such as a database record predicate evaluation, can check for the completion of the PIE-PF operation by examining an indicator in a control block in shared storage. Furthermore, if the parallel operation has not completed, the CPU can: a) continue the PIE-PF processing in parallel with other processing in the CPU, b) halt the parallel PIE-PF asynchronous operation and have the CPU do the rest of the operation synchronously, or c) resume the parallel operation in the processor or a hardware assist if an interruption caused the PIE-PF parallel operation to be checkpointed.

摘要： A coexecutor for executing functions offloaded from central processors (CPs) in a data processing system, as requested by one or more executing control programs, which include a host operating system (host OS), and subsystem programs and applications executing under the host OS. The offloaded functions are embodied in code modules. Code modules execute in the coexecutor in parallel with non-offloaded functions being executed by the CPs. Thus, the CPs do not need to execute functions which can be executed by the coexecutor. CP requests to the coexecutor specify the code modules which are accessed by the coexecutor from host shared storage under the same constraints and access limitations as the control programs. The coexecutor may emulate host dynamic address translation, and may use a provided host storage key in accessing host storage. The restricted access operating state for the coexecutor maintains data integrity. Coexecutors can be of the same architecture or of a totally different architecture from the CPs to provide an efficient processing environment for the offloaded functions. The coexecutor interfaces host software which provides the requests to the coexecutor. Offloaded modules, once accessed by the coexecutor, may be cached in coexecutor local storage for use by future requests to allow subsequent invocations to proceed without waiting to again load the same module.

摘要翻译： 用于执行由数据处理系统中的中央处理器（CP）卸载的执行器，如由一个或多个执行控制程序请求的，其包括主机操作系统（主机OS）以及在主机OS下执行的子系统程序和应用程序。 卸载的功能体现在代码模块中。 代码模块在执行程序中执行，与CP执行的非卸载函数并行执行。 因此，CP不需要执行可由coexecutor执行的功能。 向请求者执行的CP请求在与控制程序相同的约束和访问限制下指定由主机共享存储器由coexecutor访问的代码模块。 共同执行者可以模拟主机动态地址转换，并且可以使用提供的主机存储密钥来访问主机存储。 coexecutor的受限访问操作状态维护数据完整性。 共同执行者可以是与CP相同的架构或与CP完全不同的架构，为卸载的功能提供有效的处理环境。 接口主机将向主机提供请求的主机软件。 卸载的模块一旦被coexecutor访问，就可以被缓存在coexecutor本地存储器中，供将来的请求使用，以允许后续的调用继续进行，而不用等待再次加载相同的模块。

摘要： A method, storage server, and computer readable medium for off-loading star-join operations from a host information processing system to a storage server. At least a first and second set of keys from a first and second dimension table, respectively are received from a host system. Each of the first and second set of keys is associated with at least one fact table. A set of locations associated with a set of foreign key indexes are received from the host system. A set of fact table indexes are traversed. At least a first set of Row Identifiers (“RIDs”) associated with the first set of keys and at least a second set of RIDs associated with the second set of keys are identified. An operation is performed on the first and second sets of RIDs to identify an intersecting set of RIDs. The intersecting set of RIDs are then stored.

摘要： A Resource Management and Reservation System (RMRS) for managing and reserving storage bandwidth, is a platform independent middleware layer that provides an interface to applications, their database management systems, or some other higher level data management systems like ADRS which does data management on behalf of the applications. RMRS is highly relevant in hosted environments where one or more applications may be run on behalf of multiple customers each with a unique service level agreement with the Service Provider. Through its interface to the aforementioned applications, RMRS allows each application or an application side management system to communicate expected future storage access requirements (e.g., periodic access for backups). The interface also allows applications to request urgent storage access (e.g., recovery actions may be requested without being planned ahead of time).

摘要： A system and method for replicating files in a source file system that is linked to a source DBMS which stores metadata pertaining to files in the source file system. The files and metadata are replicated to a target system having a target file system linked to a target DBMS. File references are also mapped from the source to the target. Also, only the most recent consistent version of files that have changed at the source and that have had insert or update references in the source DBMS are copied over to the target file system, thereby minimizing unnecessary replications.

摘要： A computing system provides continuous availability of data files that are maintained at a file management system and linked to a database management system (DBMS) through a Datalink data type, even while any particular file is being changed with DBMS append or update operations. When a file is linked, it is designated to be available for read-only operations. A user who wants to perform updates on a file gets a "check-out" copy of the file for updating operations, such that the original file remains linked to the database system while the copy is being updated and remains available to other users. The file management system includes a "check-in" function that receives the updated file, saves the updated file under a new name different from the original, updates the Datalink, generates new metadata for the updated file, and transactionally updates the file with its new metadata. In this way, data files are continuously available to all users through appending and updating actions. Since updating Datalinks requires the file management system to initiate backup, a "delta versioning" operation, which reduces the data needed to support backup operations, permits more efficient backup of data files and enables the continuously available files to be backed up and consistent.
