When an item expires, it is still retained in the database. In addition, you can also retain deleted items in the database. Periodically you may want to perform a system purge to permanently remove expired and deleted items from the database.
To
perform a system purge, you must have at least one of the following privileges:
Manage All privileges on the page group
Manage All global privileges on All Page Groups
When you perform a system purge, items are permanently removed from the database.
In the Navigator, click Properties next to the page group with which you want to work.
Click the Items tab.
Select Retain Deleted Items.
Select Purge Deleted Items to remove deleted items during the system purge.
Select Purge Expired Items to remove expired items during the system purge.
Click Purge.
When the purge is completed, click OK to return to the Navigator.
A system purge may take a few minutes if there are a lot of deleted or expired items.
