To run sysinfo from the command line, use a command like one of the following while the Network Server is running.
java -jar $DERBY_HOME/lib/derbyrun.jar server sysinfo
[-h hostname][-p portnumber]
java org.apache.derby.drda.NetworkServerControl sysinfo [-h hostname][-p portnumber]
Administrative commands such as sysinfo can only execute on the host where the server was started, even if the server was started with the -h option.
