Hi Chris,
I don't know whether you have seen the startNetworkServer script which
is supplied in the bin directory of Derby distributions. It may do a lot
of your work for you. For more information on starting up the network
server, please see the section titled "Starting the Network Server" in
the Derby Server and Administration Guide:
http://db.apache.org/derby/docs/10.4/adminguide/
Hope this helps,
-Rick

Hi,
I've searched the FAQ, wiki and Nabble's archive for this list but not
found an example init script for running Derby's Network Server. I have
put together a basic init script, but it has one problem which I am
hoping someone on the list can solve for me. The script works fine when
the server is rebooted, but if I login via ssh and restart Derby with
the init script, my shell hangs when I logout. I guess that even though
I run the init script as root, the Derby process is somehow associated
with my login session and prevents me from successfully logging out. I
don't want to use nohup, as it leaves an annoying log file laying around
- there must be a better solution!
My init script is as follows:
#!/bin/sh
# Starts and stops the derby database
DERBY_HOME=/home/derby
DERBY_USER=derby
derby_start () {
su -l $DERBY_USER -c "$DERBY_HOME/bin/start_derby >
$DERBY_HOME/logs/derby.log &"
}
derby_stop () {
su -l $DERBY_USER -c "$DERBY_HOME/bin/stop_derby >
$DERBY_HOME/logs/derby.log &"
}
case "$1" in
start)
derby_start
;;
stop)
derby_stop
;;
restart)
derby_stop
sleep 5
derby_start
;;
*)
echo "Usage: /etc/init.d/derby {start|stop|restart}"
exit 1
;;
esac
exit 0
The start script is as follows:
#!/bin/sh
start_command="exec $JAVA_HOME/bin/java $DERBY_OPTS -classpath
$DERBY_CLASSPATH org.apache.derby.drda.NetworkServerControl start $@"
eval $start_command
And the stop script is as follows:
#!/bin/sh
stop_command="exec $JAVA_HOME/bin/java $DERBY_OPTS -classpath
$DERBY_CLASSPATH org.apache.derby.drda.NetworkServerControl shutdown $@"
eval $stop_command
The following relevant entries are in the derby user's shell config:
JAVA_HOME=/usr/java/default
PATH=$PATH:$JAVA_HOME/bin
export JAVA_HOME PATH
DERBY_HOME=$HOME
DERBY_CLASSPATH="$HOME/lib/derbynet.jar:$HOME/lib/derby.jar"
DERBY_OPTS="-Dderby.system.home=$HOME/derby"
export DERBY_HOME DERBY_CLASSPATH DERBY_OPTS
