    摘要: An apparatus, system, and method are disclosed for efficient adaptive parallel data clustering for loading data into a table by generating a hint-key for each of one or more records in the input data stream, ordering the one or more records in a first-level clustering agent to generate one or more record lists ordered by hint-key. The apparatus, system, and method simultaneously processes one or more record lists in a second-level clustering agent, outputs the one or more records of the one or more record lists clustered by the hint-key of the one or more records, stores, in a partial block cache, a plurality of partial blocks that are output by the second-level clustering agent, and stores, in a partial page cache, a plurality of last partial pages of the partial blocks that have been victimized from the partial block cache.

    摘要: A transactional database server is accessible by applications. Applications indicate whether access is made using an online protocol. Where the database server determines that a request received from an application is made using the online protocol, the server will return one of a set of defined error codes upon identified system resources being determined to be scarce. Applications monitor responses from the database server for the defined error codes. On receipt of one of the defined error codes an application will issue a commit to the database server to attempt to release system resources for use by applications.

    摘要: A system and associated method load an input data stream into a multi-dimensional clustering (MDC) table or other structure containing data clustered along one or more dimensions, by assembling blocks of data in a partial block cache in which each partial block is associated with a distinct logical cell. A minimum threshold number of partial blocks may be maintained. Partial blocks may be spilled from the partial block cache to make room for new logical cells. Last partial pages of spilled partial blocks may be stored in a partial page cache to limit I/O if the cell associated with a spilled block is encountered later in the input data stream. Buffers may be reassigned from the partial block cache to the partial page cache if the latter is filled. Parallelism may be employed for efficiency during sorting of input data subsets and during storage of blocks to secondary storage.
