You can specify that maintenance be triggered when:
A condition, such as low disk space, occurs or
On a periodic or gated interval
Select the Maintenance Events tab in the EM_LOG Table Properties dialog box.
Specify actions the same way you specify them for atable.
Important: (For SQL Server) insert triggers fire only if bulk insertion is disabled.
