Abstract
A method for tuning a database system is disclosed. A tuning strategy is received comprising a first procedure to determine a suggested tuning action, and a second procedure to measure performance of the database system. The suggested tuning action is determined and pre-action performance measured according to the respective procedures. Undo information that indicates how to undo the database system state change of the suggested tuning action is recorded in a database system state history. After executing the suggested tuning action, post-action database system performance is measured according to the second procedure. When the post-action performance is lower than the pre-action performance, the database system state change is undone using the undo information. Embodiments enabling to create new tuning strategies, downloading existing tuning strategies, sharing own tuning strategies and changing existing tuning strategies are disclosed as well.
