What is the logic behind the oracle database connections....

Question

Hi,
We have crontab alerts are enabled for the oracle database client connection.
For Production databases the alerts are coming continuously until it gets connected.
For QA databases it will throw the message that the oracle client connection fails and again it will prompt whenever it gets connected.
Please let me know the logic behind these scnerions.
Pavan..

Hi,
Thanks for the update, Sorry the question was not clear. let me put it in a clear way.
Following is our crontab which alerts us if any database/listener goes down. But it alerts us only once for one successful/unsuccessful connection. For Eg: If the crontab not able to connect to the database for once then it throws an alert only once and waits for a successful connection.
I would like to change the logic in this crontab in such a way that, it should keep on alerting us for all the unsuccessful connections and once or twice for successful connection.
. /home/oracle/.bash_profile
. /opt/oracle/cron/cron_email
sidfile=/home/oracle/scripts/db-list.txt
dboutfile=/home/oracle/scripts/dboutfile.tmp
echo $ORACLE_HOME
TNS_DIR=$ORACLE_HOME/network/admin
ORA_BIN=$ORACLE_HOME/bin
cat $sidfile | while read SIDNAME
do
$ORA_BIN/sqlplus -s system/******@$SIDNAME 2> /dev/null >> $dboutfile <<EOF
@/home/oracle/scripts/db_up.sql
EOF
if [ $? -eq 0 ]
then
STATUS=1
if [ -f /home/oracle/scripts/${SIDNAME}-down.txt ]
then
/bin/mail -s "Alert :Oracle database instance \"${SIDNAME}\" is up & connected..." [email protected] </dev/null
rm -rf /home/oracle/scripts/${SIDNAME}-down.txt
fi
else
if [ -f /home/oracle/scripts/${SIDNAME}-down.txt ]; then
echo "";
else
touch /home/oracle/scripts/${SIDNAME}-down.txt
echo ${SIDNAME} "not Connected ..."
/bin/mail -s "Alert :Oracle database instance \"${SIDNAME}\" is down......" [email protected] </dev/null
fi
fi
done
Thank you.
