Problem:

I installed DirXML Remote Loader using the script from http://www.novell.com/coolsolutions/feature/16975.html

With this script it is not possible to see easily if the DirXML Remote Loader is started or not.

It can be done with ps -ef |grep dirxml, but that will fill up the screen with a lot of Java classes.

Solution:

I added a section to the script to make status checking possible, like every decent script should have.

Example:

This example is for a SAP DirXML driver. The variables DIRXML_HOME, DIRXML_CONF, REMOTELOADER, REMOTELOADERPASSWD and DRIVERPASSWD are probably different on your system, double check this before using the script on a production system.

DIRXML_HOME="/usr/lib/dirxml"

       "start" )
               /bin/echo -n "Setting up DirXML Remote Loader..."
               cd $DIRXML_HOME
               $REMOTELOADER -config $DIRXML_CONF -sp $REMOTELOADERPASSWD $DRIVERPASSWD
               /bin/echo -n "Starting the DirXML Remote Loader..."
               $REMOTELOADER -config $DIRXML_CONF &
               sleep 1s
               # This is probably not the best way to get the PID, but it certainly works. Change 8001 to whatever the local listening port is.
               netstat -plant | grep LIST | grep java | grep 8001 |awk '{print $7}' | awk -F "/" '{print $1}' > $PIDFILE
               echo "done"
       ;;

       "stop" )
               /bin/echo -n "Stopping the DirXML Remote Loader..."
               /bin/kill `cat $PIDFILE`
               rm -f $PIDFILE
               /bin/echo "done"
       ;;

       "status" )
              PRG_PID=`cat $PIDFILE`
              if [ "$PRG_PID" ]; then
                  echo "DirXML Remote Loader is running with pid $PRG_PID"
                  exit 0
              else
                  echo "DirXML Remote Loader is not running"
                  exit 1
              fi
       ;;

       * )
               /bin/echo "Usage: /etc/init.d/novell-remoteloader {start|stop|status}"
               exit 1
       ;;
esac

exit 0

Environment:

The script should work on almost every Linux version, as long as you use bash shell.

Tested on Linux 2.6.5-7.286-smp, SLES9 SP3 AMD64
