This option specifies the level of permission required for a user to cause a new database file to be loaded by the database
server, or to stop a database on a running database server.
When the option is set to DBA, the client application must use an existing DBA connection to another database running on the
same server to start and stop databases. Simply having a connection to the server is not enough.
You can obtain the setting of the -gd option using the StartDBPermission server property:
SELECT PROPERTY ( 'StartDBPermission' );
The permissions for stopping a database server are specified by the -gk option.
