To shut down a Network Server, you can invoke a script, a jar
file, or a class.
The scripts to shut down a Network Server are located in the
$DERBY_HOME/bin
directory.
Important: If user authentication is enabled, you must specify a
valid Derby user name
and password; if the user authentication check fails, you'll see an
authentication error and the running server remains intact. Note that Derby does not yet restrict
the shutdown privilege to specific users: the server can be shut down by
any user on the server machine who presents valid credentials.
