What causes this issue?

In order to ensure full restoration of the database after importing a
database backup, you must activate logging of changes in log files. You
must also set the two database configuration parameters LOGRETAIN and
USEREXIT correctly.

overwritten and reused. It is then no longer possible to restore the
database to the most up-to-date state.

How to fix this error?

Set the parameter using the command:
<LB>UPDATE DB CFG USING LOGRETAIN ON</>

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
