When you secure features for a database server using the -sf option, you can also include the -sk option, which specifies
a key that can be used with the secure_feature_key database option to enable secured features for a connection. That connection
can also use the sa_server_option system procedure to modify the features or feature sets that are secured for all databases
running on the database server.
If the secure_feature_key option is set to any value other than the one specified by -sk, no error is given, and the features
specified by -sf remain secured for the connection.
The following command starts a database server named secure_server with access to the backup features disabled. The key specified
by the -sk option can be used later to enable these features for a specific connection.
dbsrv12 -n secure_server -sf backup -sk j978kls12
Setting the secure_feature_key option to the value specified by -sk for a connection to a database running on the secure_server
database server allows that connection to perform backups or change the features that are disabled on the secure_server database
SET TEMPORARY OPTION secure_feature_key = 'j978kls12';
The user could then disable the use of all secured features for databases running on secure_server by executing the following
