Manage Windows Scheduled Tasks
A scheduled task is created when you schedule a Space Manager activity such as report generation or script generation. When you schedule one of these activities, a Windows scheduled task is created. You can view and manage these tasks using Space Manager.
Scheduled tasks that are managed using the Scheduled Tasks window include:
- Scheduled script generation for Live Reorg scripts. See About Scheduling a Recurring Reorganization for more information.
- Scheduled report generation, such as Predicted Benefit Reorg reports.
When a scheduled task is executing, Space Manager runs in the background.
To manage scheduled tasks
- Select Manage | Scheduled Tasks. The Space Manager Scheduled Tasks window opens.
-
Review the list of scheduled tasks. The grid displays the status of each task and the next scheduled run time.

Report Basics
Space Manager provides Reorganization reports to identify the benefits of reorganizing tables or indexes and to capture historical data on reorganization activity.
Space Manager provides Size and Growth reports for capacity and reorganization planning.
All reports can be viewed, printed, and exported. Space Manager allows you to easily export a report and then email it to colleagues. You can export a report to one of a number of different file formats, including PDF, Excel, or a text file.
Notes:
- Reports are generated from statistics stored in the Space Manager Repository. To accumulate statistics in the Repository, make sure the Repository is updated on a regular basis.
- The date that a Repository was last updated is displayed in the Repository Status panel in the Explorer window when a database is selected.
- To check or modify the update schedule, select Tools | Admin | Change Repository Update Schedule.

Generate Reorganization Reports
There are two types of Reorganization reports you can generate.
- The Predicted Reorganization Benefit report shows you the amount of space you can reclaim if you reorganize a selected table or index.
- The Reorganization History report shows which tables or indexes were reorganized during the selected time period, which allows you to extrapolate space savings due to reorganization activity. For planning reorganizations in the future, this report provides you with historical information on how much time it took to run reorganizations on specific objects.
