    摘要: An apparatus and system are disclosed for reorganizing a set of database partitions based on a ranked set of database partitions. The apparatus includes an evaluation module to determine a fragmentation indicator for each database partition within a set of database partitions. A ranking module ranks the set of database partitions according to a rank criteria. The rank criteria includes, at a minimum, the fragmentation indicator. A reorganization module reorganizes a subset of the database partitions in the ranked set of database partitions. The subset is selected, at least in part, by a rank order for the ranked set of database partitions. The subset may be selected such that ranked database partitions satisfying a dynamic reorganization threshold are included in the subset.

    摘要: A method is disclosed for reorganizing a set of database partitions based on a ranked set of database partitions. The method includes a step to determine a fragmentation indicator for each database partition within a set of database partitions. A step ranks the set of database partitions according to a rank criteria. The rank criteria includes, at a minimum, the fragmentation indicator. A step reorganizes a subset of the database partitions in the ranked set of database partitions. The subset is selected, at least in part, by a rank order for the ranked set of database partitions. The subset may be selected such that ranked database partitions satisfying a reorganization threshold are included in the subset.

    摘要: An apparatus, system, and method are disclosed for determining the consistency of a database including indirect reference to data elements. There is provided an apparatus for determining consistency of a database. This database includes, in association with each data element, an indirect list element including a storage address of the associated or corresponding data element so that other data elements can reference that data element. This apparatus reads, from each data element, identification information of an indirect list element corresponding to that data element and generates a hash value. This apparatus further reads, from each data element, identification information of an indirect list element corresponding to a data element referenced by that data element and generates a hash value. On condition that these hash values are equivalent to each other, the apparatus determines that the database is consistent.
