Hi Guys,

problem statement - I wish to come up with a script which sends an email as soon as tnslsnr and pmon process are back online after a backup is complete.

Detailed description - We have a few Solaris servers. A daily backup is taken on all of them. Before a backup is taken, pmon process and tnslsnr are taken down (achieved via a script ). This is done at a fixed time everyday.

Depending on how much time it takes, the pmon and the tnslsnr stay down. Now, I wish to create a script which sends an email telling that the pmon and tnslsnr are back running after the backup.

PS : I can write a script which runs periodically (lets say every 20 minutes) using the ps -ef and checks for the process with something like this :

#!/bin/ksh
pid=""
pid=ps -ef | grep <user> | grep -v grep | grep <process string> | awk '{print $2}'
echo $pid
if [ "$pid"="" ]
then
echo "process not running"
rsh <mail server> mailx -s "<etc etc process not running>" <mail.id>
else
echo service is ok
pid=""
fi


But I wish to achieve this without running the script periodically. I was hoping to maybe capture an event somehow/somewhere, as soon as pmon and tnslsnr are back running and use it to write my script.
Is there a file/log that captures when all the processes are down or running? and If yes, is there a way to use that info in generateing a script for my problem above ?

any help or insight into my querry is much appreciated !!!

You can watch the oracle logs but that's much the same procedure as doing you current polling of the process table.

I'd think tying something into the script that starts the listener after the backup would be simpler. Just have it call your email script once it's done with the backup?
