What must happen whenever changes are made to the dbparm.ini file?

Whenever changes are made to the dbparm.ini file, it is essential to restart the Vault Service. The dbparm.ini file contains configuration parameters that the Vault Service uses to determine how it operates and accesses the database. These parameters may include settings about database connections, timeout settings, and other critical operational parameters.

When updates are made to this configuration file, they will not take effect until the Vault Service is restarted. This is because the service reads these settings into memory during startup. By restarting the service, the new configuration settings are applied, ensuring that the Vault operates according to the latest configurations defined in the dbparm.ini file.

The other options do not accurately describe the necessary actions related to changes made to this file. Generating new keys or logging out all users may not be relevant for changes to the dbparm.ini, and in most cases, simply making changes does require some action, specifically the restart of the Vault Service.
