This is hugly and not optimized but i think it does the work :

Code:
$ cat myfile
#!/usr/bin/ksh
f1=${1:-9i.ora}
f2=${2:-11g.ora}
printf "%-29s\t%40s\t%40s\n" "Param" "9i" "11g" >output.err
printf "%-29s\t%40s\t%40s\n" "Param" "9i" "11g" >output.ok
printf "%-29s\t%40s\t%40s\n" "Param" "9i" "11g" >output.all
while read p n
do
v9=$(grep $p $f1 | sed 's/.*=//' 2>/dev/null)
v11=$(grep $p $f2 | sed 's/.*=//' 2>/dev/null)
echo "p=$p v9=$v9 v11=$v11"
printf "%-29s\t%40s\t%40s\n" $p ${v9:-"---"} ${v11:-"---"} >>output.all
case $n in
1)
        if [[ $v9 != $v11 ]]; then
echo "Warning : $p does not have the same values in $f1 and $f2 : missmatch !" >>output.err
                printf "%-29s\t%40s\t%40s\n" $p ${v9:-"---"} ${v11:-"---"} >>output.err
        else
                printf "%-29s\t%40s\t%40s\n" $p ${v9:-"---"} ${v11:-"---"} >>output.ok
        fi
;;
2)
if [[ -z "${v11}" ]]
then
        echo "Warning : $p is missing in file $f2" >>output.err
        printf "%-29s\t%40s\t%40s\n" $p ${v9:-"---"} ${v11:-"---"} >>output.err
else
        printf "%-29s\t%40s\t%40s\n" $p ${v9:-"---"} ${v11:-"---"} >>output.ok
fi
;;
3)
        if [[ -z "${v9}" ]]
        then
                echo "Warning : $p is missing in file $f1" >>output.err
                printf "%-29s\t%40s\t%40s\n" $p ${v9:-"---"} ${v11:-"---"} >>output.err
        elif [[ -n "${v11}" ]]
        then
                echo "Warning : $p should not be in file $f2" >>output.err
                printf "%-29s\t%40s\t%40s\n" $p ${v9:-"---"} ${v11:-"---"} >>output.err
        else
                printf "%-29s\t%40s\t%40s\n" $p ${v9:-"---"} ${v11:-"---"} >>output.ok
        fi
;;
esac

done<listparam

Note that listparam should have lines looking like <parameter_name> <number_of_the_requirment>
Code:
$ cat listparam
db_block_size 1
db_cache_size 1
db_file_multiblock_read_count 1
open_cursors 1
cursor_sharing 1
background_dump_dest 1
core_dump_dest 1
user_dump_dest 1
diagnostic_dest 2
db_unique_name 2
memory_max_target 2
memory_target 2
pga_aggregate_target 3
java_pool_size 3
large_pool_size 3
shared_pool_size 3
$

This will generate 3 output :

output.all (for an overview of all the parameter value in each of the file '---' if not found or empty)

output.err (with an error message saying what's going wrong)

output.ok (containing parameters that do not match your error requirements)

feel free to change the default value for f1 and f2 to some other filename that match yours.


Code:
$ cat output.all
