Abstract
There is disclosed a data processing system implemented method, a data processing system, and an article of manufacture for directing a data processing system to maintain a database table associated with an initial maintenance scheduling interval. The data processing system implemented method includes selecting a randomizing factor, and selecting a new maintenance scheduling interval for the database table based on the initial maintenance scheduling interval and the selected randomizing factor.
Claims36
A data processing system implemented method for directing a data processing system to maintain a database table associated with an initial maintenance scheduling interval, the data processing system implemented method comprising:
- selecting a randomizing factor;
- and
- selecting a new maintenance scheduling interval for the database table based on the initial maintenance scheduling interval and the selected randomizing factor.
A data processing system for maintaining a database table associated with an initial maintenance scheduling interval, the data processing system comprising:
- a selecting module for selecting a randomizing factor;
- and
- a selection module for selecting a new maintenance scheduling interval for the database table based on the initial maintenance scheduling interval and the selected randomizing factor.
An article of manufacture for directing a data processing system to maintain a database table associated with an initial maintenance scheduling interval, the article of manufacture comprising:
- a program usable medium embodying one or more instructions executable by the data processing system, the one or more instructions comprising:
- data processing system executable instructions for selecting a randomizing factor;
- and
- data processing system executable instructions for selecting a new maintenance scheduling interval for the database table based on the initial maintenance scheduling interval and the selected randomizing factor.
