You can change scheduled times for the default grooming jobs
using SQL Server Enterprise Manager.
If you change the default scheduled times for database
grooming, the new times must not interfere with other scheduled
Microsoft Operations Manager 2000 tasks. For example, do not
schedule a database grooming job for 2:05 A.M., the default time to
scan for managed computers.
To change scheduled database grooming:
Log on with an Administrator account to the computer on which
you installed the database.
Run Enterprise Manager from the Microsoft SQL Server
Expand SQL Server Group.
Expand the server that contains the Microsoft Operations
Manager 2000 database.
Expand SQL Server Agent.
Click Jobs in the left pane.
Select the job you want to reschedule.
Select the Schedules tab.
Click Edit on the Properties window.
Click Change on the Edit Job Schedule window.
Specify the desired values on the Edit Recurring Job Schedule
window, and then click OK.
Click OK on the Edit Job Schedule window.
Click OK on the Properties window, and then click
