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.
#
# Author : Kirti Deshpande
#-----------------------------------------------
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
# --- End of File
