I enabled the Full Administrator Access feature and verified that this activity had been logged in the LOG.NSF.
According to the Admin Help, any database activity done using full access admin access is recorded in the DB activity log under Database Properties.
So I was experimenting with unchecking the 'Record activity’option in the properties and then updated and deleted some documents in the database. I later discovered that there was no entry in the DB properties!
Am I missing something or this works as designed?
