Enterprise manager allows you to view reports interactively and/or schedule generation of reports on a flexible schedule. For example, you might want to generate an "Inventory Snapshot" report of all of the servers in your environment every day at midnight.
Cloud Control provides the following scheduling options:
One-time report generation either immediately or at any point in the future
Periodic report generation
Frequency: Any number of Minutes/ Hours/ Days/ Weeks/ Months/ Years
You can generate copies indefinitely or until a specific date in the future.
Enterprise Manager allows you to store any number of scheduled copies for future reference. You can delete each stored copy manually or you can set up automated purging based on either the number of stored copies or based on retention time. For example, you can have Enterprise Manager purge all reports that are more than 90 days old.
