auto-restart clients 🔗 link

Hello all,
 For reasons which I cannot understand, our unix admins feel the need to
reboot their machines constantly. I don't think there is an uptime
exceeding 2 weeks!! However when that happens, the BB client stops
reporting and I eventually get the purple alerts from Hobbit. Can
someone tell me how to get the clients to auto-restart? Also, I am not a
coder so please don't tell me to "write a script to make them start at
reboot" because that is obvious....i just don't know how. Thank you for
all input on this.

  "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

Here is the script we use. This one is from a Linux machine and you will need to set BBHOME and BBUSER. Under Linux you can use the chkconfig command to add this. Under other OSes you will need to link it to the run levels you want it to start/stop. Any UNIX administrator should be able to do this or you are paying them too much.

If you are running HP_UX replace /etc with /sbin

Link with:

ln -s /etc/init.d /bigbrother /etc/rc2.d/S99bigbrother

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

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,

Since there also were stop in the script you should also link the script to /etc/rc1.d/K01bigbrother to automatically stop bigbrother

Ie. ln -s /etc/init.d/bigbrother /etc/rc1.d/K01bigbrother

Gentlemen,
  Thank you all for your responses and input for the auto restart
problem I was having. I will try all the suggestions posted here. I have
gotten better, faster, more intelligent, and more accurate, well thought
out responses here than I have EVER received from any "commercial"
product and I appreciate it. Henrik has done an astounding job of
producing a product that is extremely useful and actually works (as
opposed to the usual commercial product "we'll fix it in the next
release" but it still costs 300 thousand dollars!) but the support
afforded by this message board exceeds any tech support I have ever seen
and I thank you all for it!
 
Sincerely
 
Kevin
