摘要: The subject disclosure is directed towards defragmenting one or more ranges of a database index based upon actual usage statistics and policy. A range tracker tracks and uses statistics corresponding to actual I/O operations to determine whether the benefit of defragmenting a range sufficiently (based upon the policy) exceeds its cost. If so, the online range defragmenter automatically defragments the range in an online manner. The range tracker may be configurable to monitor less than all ranges of the index.

摘要: An automated physical database design tool may provide an integrated physical design recommendation for horizontal partitioning, indexes and indexed views, all three features being tuned together (in concert). Manageability requirements may be specified when optimizing for performance. User-specified configuration may enable the specification of a partial physical design without materialization of the physical design. The tuning process may be performed for a production server but may be conducted substantially on a test server. Secondary indexes may be suggested for XML columns. Tuning of a database may be invoked by any owner of a database. Usage of objects may be evaluated and a recommendation for dropping unused objects may be issued. Reports may be provided concerning the count and percentage of queries in the workload that reference a particular database, and/or the count and percentage of queries in the workload that reference a particular table or column. A feature may be provided whereby a weight may be associated with each statement in the workload, enabling relative importance of particular statements to be specified. An in-row length for a column may be specified. If a value for the column exceeds the specified in-row length for that column, the portion of the value not exceeding the specified in-row length may be stored in the row while the portion of the value exceeding the specified in-row length may be stored in an overflow area. Rebuild and reorganization recommendations may be generated.

摘要: A plurality of indicators representing a plurality of respective candidate database configurations may be obtained, each of the candidate database configurations including a plurality of database queries and a plurality of candidate database indexes associated with a database table. A portion of the candidate database indexes included in the plurality of database indexes may be selected based on skyline selection. An enumeration of the portion of the plurality of the candidate database indexes may be determined based on a greedy algorithm.

摘要: This patent application relates to granular and workload driven database index defragmentation techniques. These techniques allow for defragmenting individual index ranges, performing benefit analyses to estimate the impact of defragmenting indexes or index ranges, and leveraging such benefit analyses to provide automated workload-driven recommendations of index(es) or index range(s) to defragment.

摘要: An automated database tuning tool may include a user interface component and a tuning engine. The user interface may be a graphical component that interfaces with a user to collect configuration parameters for a tuning session for a specified database. The configuration parameters may be stored in a tuning database. A tuning engine that performs the actual tuning process may generate physical design recommendations and reports. The recommendations and reports may be stored in the tuning database, enabling the tuning tool to be run off-line or in background. Communication between components of the tuning tool may occur via stored procedures.

摘要: Internal communications within components of an automated physical database design tool may be conducted in a data description language such as XML. Inputs to and outputs from the automated physical database design tool may also be presented in the data description language (e.g., XML). The communications, inputs and outputs may comply with a schema for the data description language. The schema may be written in a schema language such as XSD. Inputs presented in the data description language may comprise tuning options. Outputs may comprise a proposed physical design for a database and reports.
