Abstract
A query governor intelligently sets tailored thresholds for a query accessing a computer database. The query governor preferably generates a tailored threshold for each query sent to the database for execution. The tailored threshold for the query is preferably compared to an estimated query execution time to determine whether to execute the query. The query governor uses one or more factors applied to a standard threshold to generate the tailored threshold. The factors preferably include user factors and query factors. These factors are dynamically adjusted by the query governor in an intelligent way to increase optimal use of the database. Other factors may include factors such as job priority factor, resource factor and an application factor.
