Solaris

Hi,


is there something build in solaris that can act as "watchdog".
I have some process (service) running (e.g. Rhino). It can happen that if freezes totaly so I need to find this out and restart it totaly.

My vision is two possibilities.
1) there is some counter running and I will arrange that my process reset the counter in some time interval. In case it will not, the service providing the counter will restart my process no matter if it's running or not.

2) some service will communicate with my process in some time intervals (I can put into my process some reply on some question) and in case he will no get answer, he restarts my process.


however, you surely know what I need. I know it can be programmed additionaly but....isn't there some watchdog functionality already build into solaris (10).


thanks a lot

unbelievable I found this page already yeasterday and I put it immediatelly to my bookmarks. really nice one. However I know how to solve that in this way. cron and this one :

Code:

#!/bin/sh
if [ ! `/usr/bin/pgrep Rhino` ] ; then
nohup ./Rhino-blabla &
fi
exit 0

I was curious if there is some build in watchdog in solaris
OK, when this is the only one , I can live with it.

but what about some process which stays in memory , but is frozen (I'm just on theoretical level. can not give any example)
