RE: db_file_multiblock_read_count

How do you know you're "being ignored"? Just because it shows a value of 128 doesn't mean your "reset" isn't working - maybe 128 is the value that Oracle is coming up with? Try this:

select isdefault from v$parameter where name = 'db_file_multiblock_read_count';

If it's not the default, you might want to try this:

alter system reset db_file_multiblock_read_count scope=spfile sid = '*';

Then bounce your instance and check again.
