By default, Configuration Manager 2007 schedules updates preinstalled collections for once per day. As administrator, it is up to you to set the schedule for updating new collections (by default the schedule for new collections is also set at once per day). However, depending on the number and size of your collections, as well as the frequency with which your resource list changes, you can optimize Configuration Manager 2007 performance by adjusting the length of time between collection updates.
You can schedule collection updates when you create a collection using the New Collection Wizard, or later, using the Collection Properties dialog box. Both use the same user interface.
|You must have Modify permissions for the Collection security object type to set a collection update schedule. For more information about security permissions, see Classes and Instances for Object Security in Configuration Manager.|
To schedule a collection update
In the Configuration Manager console, navigate to System Center Configuration Manager / <server name> / Computer Management / Collections.
Right-click the collection that you want to schedule, and then click Properties.
On the Membership Rules tab, select the Update this collection on a schedule check box if not already selected.
Specify when and how often you want to update collection membership in the Custom Schedule dialog box, specifying a start time and recurrence pattern for updating the collection membership.
For more information about this dialog box, see Custom Schedule Dialog Box.
