UNIX for Dummies Questions & Answers

Hello friends,

I am new to shell scripting.I am assigned a task in Unix to prepare a script which will check if OBI 10g services are running or not and to send email if the services are down.Any help will be appreciated. I tried searching for it in the blog and came across the following code

echo "Check OBI service.." >> $LOGFILE
ps -ef | grep sawserver >> $LOGFILE
obisrvc_count=`ps -ef | grep sawserver | grep -v grep | wc -l`
if [ $obisrvc_count -gt 0 ]
then
echo "OBI Service Running.." >> $LOGFILE
flag=0
else
echo "OBI Service NOT Running.. Please check.." >> $LOGFILE
flag=2
fi
}

I would also need a mail to be triggered to specific group, once the BI server is identified to be down, can any1 help me with this.

First of all there is no need to pipe grep command result to wc -l command. You can use grep -c to count matching lines.

OR

Code:

if ps -ef | grep sawserver | grep -v grep > /dev/null
then
        echo "OBI Service Running.." | tee $LOGFILE
        flag=0
else
        echo "OBI Service NOT Running.. Please check.." | tee $LOGFILE  | mailx -s "OBI Service NOT Running" user@domain.com
        flag=2
fi
