Scritping Problem

[Dewa Negara_2]

Hi Folks,

I have a scripting problem here.If anyone can help me on this.I have a simple script like below :
numwork=`hrtest getconf|grep local | wc -l`
echo Number of workers is $numwork

if [ $numwork -lt 1 ]; then
echo HyperRoll is down.Send alert to DM
fi

where hrtest is a specific application command. But sometime hrtest command got hang on the system, and did not give any error. So how can I detect this problem when hrtest got hang? can I add a logic to detect it? or how can we stop the hang process? so it will give an information that hrtest is hang.

Thanks in advance.

a simple logic i use normally

save this as a separate script. use another script to run this in background. and sleep for some time. after that see if this process is still running. in that case ur has hung and just kill it.

do let me know in case u need more info.

Balaji,

Thanks alot. Can I put like below :
#cat /tmp/script1
numwork=`hrtest getconf | grep local |wc -l`

Then on the script itself I put :
(. /tmp/script1;sleep 60) &

if [ $? -ne 0 ];then
kill -9
exit
fi

echo Number of workers is $numwork

if [ $numwork -lt 1 ]; then
echo HyperRoll is down.Send alert to DM
fi

Please confirm.
Thanks alot.

hi,
dont call the /tmp/script in background and run it from the same script. because there will be one instance always running. if you are not going to process further, then this is ok.

else, it should be another script.
