Derby Network Server advanced topics
This section discusses several advanced topics for users of the Derby Network Server.
Network Server security
By default, the Derby Network Server will only listen on the localhost. Clients must
use the localhost host name to connect. By default, clients cannot access the
Network Server from another host. To enable connections from other hosts, set the
derby.drda.host property, or start the Network Server with the
-h
option in the
java
org.apache.derby.drda.NetworkServerControl start
command.
In the following example the server will listen only on localhost and clients cannot access
the server from another host.
java org.apache.derby.drda.NetworkServerControl start
