Cleanup
An administrator can limit the size of certain tables in the database by setting appropriate options in Administration > Site administration > Server > Cleanup.
Delete unconfirmed users after
If you're using Email-based self-registration users must confirm their account (complete the email registration process) within a certain time-frame. Once the time set here has passed, any account that hasn't been confirmed will be deleted. The default is 7 days.
Delete incomplete users after
Once users have confirmed their account, they must complete their profile within the time interval set here.
A complete profile is one where the following fields have been filled in (are not empty):
- First name
- Last name
- Email address
Just as a reference, given that the firstname, lastname and email are required fields of the Upload users module, any account created this way is automatically a complete account.
Disable grade history
History tracking of changes in grades-related tables may be disabled by checking the disablegradehistory box.
Grade history lifetime
The length of time that the history of changes in grade-related tables is kept may be set (from 30 days to never).
Note for users who have upgraded from earlier versions: The setting 'Keep logs for' is now located in the log store settings.
