摘要： A method of, a computer program product for and a computer system for managing statistics in a database management system are provided. A value of a volatility of a statistic is determined. A value of a staleness of the statistic is determined using the value of the volatility. A statistics collection task is generated in response to, at least in part, the value of the staleness exceeding a value of a staleness threshold. The statistics collection task is executed to collect an additional value of the statistic. The additional value of the statistic is stored.

摘要： Provided are a method, system, an program for tuning a database query. Provided are a base access plan to implement the database query and statistics including information on a layout of the database against which the query will be executed. The statistics are processed to determine performance problems with the base access plan as part of a first analysis of the base access plan and the determined performance problems are processed as part of a second analysis to provide an analysis of the determined performance problems and processing cost of the base access plan. Recommendations are generated to tune the base access plan to improve performance.
