read yourch
case $yourch in
1)
# Start the Oracle databases:
# The following command assumes that the oracle login
# will not prompt the user for any values
# su - oracle -c "$ORACLE_HOME/bin/lsnrctl start"
is_root=`id |cut -d '(' -f2|cut -d ')' -f1`;
if [ $is_root = "root" ]
then
su - oracle -c $ORACLE_HOME/bin/dbstart
elif [ $is_root = "oracle" ]
then
$ORACLE_HOME/bin/dbstart
else
echo "You don't have permission to run this utility"
exit;
fi
;;
2)
echo "hi \c"
;;
3) exit 0
;;
*) echo "Opps!!! Please select right choice "
echo "Press a key. . ."
;;
esac
done

The screen is cleared after the echo command. Try to add a sleep command after the echo command:

Code:

2) echo "hi \c"
   sleep 2
