[hobbit] auto-restart clients

[Jeffcoat, Al]

For our AIX servers, we have an /etc/rc.local script that starts things
on startup.  In that script, we have the following command:

su - bbuser -c "/path/to/bbclient/runbb.sh start"

(If you create that script new, then make sure to make it executable,
chmod +x /etc/rc.local)

And then execute the following command:

mkitab "local:2:once:/etc/rc.local 2>&1 > /utils/logs/rc.local.output"

This will create an entry in the /etc/inittab file for the rc.local
file.  Any output from that script gets created in
/utils/logs/rc.local.output, it's useful to see if something isn't
working right.

And I have the same issue here, we have some servers that the app is so
badly written that we have to reboot weekly.  We also have others whose
uptime is 300+ days.

Hope that helps,

Gentlemen,
 Thank you for the responses. I should have mentioned that most of the
machines are solaris and a few are AIX

Normally a script like this would suffice:

#!/bin/sh

case "$1" in
  "start")
	su -c "/usr/local/bb/bbc/runbb.sh start" bb
	;;

  "stop")
	su -c "/usr/local/bb/bbc/runbb.sh stop" bb
	;;
esac

exit 0


Now the trick is to get that script run automatically when the system
starts
up. How you do that depends on the Unix flavour - often the script is
installed in /etc/init.d/bigbrother, and then you need to create links
from
/etc/rc2.d/S99bigbrother -> /etc/init.d/bigbrother

Henrik
