That is a Useless Use of cat and Useless Use of wc -l

Use an infinite while loop and break when found:
Code:
#!/bin/ksh
echo "SID must be in oratab file"
echo "Enter ORACLE_SID of Database:\c "
read ORACLE_SID
while :
do
        if [[ $( grep -wc "$ORACLE_SID" /etc/oratab ) -ne 0 ]]
        then
                echo "SID Found"
                break;
        else
                echo "nothing found"
                echo "Enter valid SID"
                read ORACLE_SID
                continue;
        fi
done
