SAP Error Message - Details

• Message class: DB6 - DB6: Alert Monitoring and Alert Configuration

• Message number: 555

• Message text: Ensuring roll forward recovery

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.

System Response

If the LOGRETAIN parameter is not set, the log files will be cyclically
overwritten and reused. It is then no longer possible to restore the
database to the most up-to-date state.
If the USEREXIT parameter is not set, there is no longer an automatic
opportunity to archive log files.

How to fix this error?

Set the parameters using the commands:
<LB>UPDATE DB CFG USING LOGRETAIN ON</>
<LB>UPDATE DB CFG USING USEREXIT ON</>

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