| 20080275840 | SELECTIVE DATABASE STATISTICS RECOLLECTION - The subject mater herein relates to database management and, more particularly, to selective database statistics recollection. Various embodiments provide one or more of system, methods, and software that identify database column and index states when statistics become stale to a point where query execution plans against respective columns and indexes fail to be efficient. These and other embodiments provide a way to update column and index statistics only when the statistics are determined to be stale. As a result, adverse database performance as a result of needless updating of database statistics is mitigated. | 11-06-2008 |
| 20090063396 | TECHNIQUES FOR PARTITIONING INDEXES - Techniques for partitioning indexes are provided. A predefined data type associated with a column of a database table is acquired. Column value statistics for the column are acquired. The values are analyzed to produce multiple partitions for the values. Each partition includes each of the values and each partition includes multiple groupings of the values. Also, each grouping of a particular partition includes a subset or range of the values. Furthermore, each grouping of a partition includes a same distribution for the values as other groupings of that partition. Each partition represents a potential partitioning index for the column and its values. | 03-05-2009 |

| 20100106708 | Eliminating unnecessary statistics collections for query optimization - A method and system for eliminating unnecessary statistics collections for query optimization in a database stored on a computer. Statistics are unnecessary when a re-generated query execution plan that does not use the statistics is equivalent to an original query execution plan that uses the statistics. To determine this, an original query execution plan is created for each query in a specified workload using the statistics in the database. A search is performed of the statistics in order to enumerate one or more candidate sets of statistics to be eliminated. One or more of the candidate sets of statistics are removed from consideration prior to creating the re-generated query execution plan for each query in the specified workload. The re-generated query execution plan, which was created with one or more of the candidate sets of statistics removed from consideration, is compared with the original query execution plan, which was created using the statistics, in order to determine whether the re-generated query execution plan and the original query execution plan are equivalent. The one or more of the candidate sets of statistics removed from consideration are identified as unnecessary when the re-generated query execution plan and the original query execution plan are equivalent. | 04-29-2010 |
| 20100169302 | SYSTEM, METHOD, AND COMPUTER-READABLE MEDIUM FOR GROUPING DATABASE LEVEL OBJECT ACCESS COUNTS PER PROCESSING MODULE IN A PARALLEL PROCESSING SYSTEM - A system, method, and computer-readable medium for grouping of database object access counts per processing module in a parallel processing system are provided. Each processing module manages an intermediate cache allocated thereto that stores database object access counts local to the respective processing module. The processing modules are configured in a hierarchical configuration and processing modules at the lowest level of the configuration forward their respective intermediate cache to a processing module configured as a parent to the respective processing module. On receipt of intermediate cache(s) from lower level processing modules, a processing module merges the received intermediate caches with the intermediate cache allocated to the processing module. The process is iteratively repeated until a root processing module receives the intermediate caches from processing modules configured as child nodes thereto. The root processing module merges the received intermediate cache(s) with the root processing module's intermediate cache thereby generating a final cache. An objects access count data structure is then generated by the root processing module. The object access count data structure of the final cache includes data blocks of object access counts where each data block is associated with a particular access module processor (AMP). The data blocks may then be forwarded to the associated AMPs. | 07-01-2010 |
