I don't how to stop after 1st failed attempt, but here is a script that I use to check if database is up or not.....

#!/usr/bin/ksh
#
# dbcheck : Script to check if datbase is up and accessible.
#                It tries to connect via SQL*Net (Net8) using a non-existing

userid and password.

echo "Enter Name of the Database SID to check if it is accessible" read DB

sqlplus -s << EOF > /tmp/$$.1
whenever sqlerror exit
aaa/aaa@$DB
exit;
EOF
egrep 'ORA-121|ORA-01034' /tmp/$$.1 > /dev/null if [[ $? = 0 ]]
then

   echo "-----> '$DB' is _NOT_ Accessible\n" else

   grep 'ORA-01017' /tmp/$$.1 > /dev/null    if [[ $? = 0 ]]
   then
     echo "-----> '$DB' is UP and Accessible\n"    else
     echo "-----> '$DB' is _NOT_ Accessible\n"    fi
fi
rm /tmp/$$.1
