The Derby system shutdown brought down the database engine. However, the
next connect command booted the database again.

Yes, that observation is correct. In Derby, shutting down the database
engine and shutting down the network server are two different concepts.

You can shut down the network server either by running

  java -jar derbynet.jar shutdown

on the command line, or by using the NetworkServerControl API. See also
this section in the administration guide:

You cannot shut down the network server from ij, as far as I know,
except if you write your own stored procedure that uses the
NetworkServerControl API.

Hope this helps,

Knut Anders
