Usage Notes

This API resets the entire configuration (except for non-updatable parameters).

To view or print a list of the current database configuration parameters for a database, use sqlfxdb - Get Database Configuration.

To view the default values for database configuration parameters, use sqlfddb - Get Database Configuration Defaults.

To change the value of a configurable parameter, use sqlfudb - Update Database Configuration.

Changes to the database configuration file become effective only after they are loaded into memory. All applications must disconnect from the database before this can occur.

If an error occurs, the database configuration file does not change.

The database configuration file cannot be reset if the checksum is invalid. This may occur if the database configuration file is changed without using the appropriate API. If this happens, the database must be restored to reset the database configuration file.

For a brief description of the database configuration parameters, see the Command Reference. For more information about these parameters, see the Administration Guide.
