Yes.
if [ -f /tmp/backup_running_$ORACLE_SID ];
then
echo "Backup crawling for $ORACLE_SID";
exit;
else
touch /tmp/backup_running_$ORACLE_SID;
fi;
Crontab emails the standard output of the script to the issuer, so you
should be fine. BTW, this is a standard shell programming solution,
nothing to do with Oracle. This is elementary, my dear Raman.

I am trying to set up a backup script to be called for various DBs in the DB server through crontab. If an instance of the script is running for the GIVEN oracle_sid I dont want another instance of the backup script to be started. However, if an instance of the script is running for a different oraclesid, I am ok with starting a new instance run of the script. Linux RHES7, bash.
I tried using grep, grep -v $$, pgrep, etc inside the script and also tried pgrep in crontab, not lucky. Web searching has not led me anywhere so far. Any short and sweet solution for this issue?
