The Start Server in Background utility (dbspawn) allows you to specify a configuration file reference in the command to be
spawned, but you cannot specify a configuration file with options for the dbspawn utility. For example, the first command
below is supported, but the second command is not supported:
The dbspawn utility is provided to start a server in the background. dbspawn starts the server in the background and returns
with an exit code of 0 (success) or non-zero (failure). If a new server is successfully started, dbspawn does not return until
the database server has completed initialization and is ready to accept requests.
By default, dbspawn cannot start a new server on a computer where a default database server is currently running. To start
a server on a computer where a default database server is running, specify the -f option.
