Getting info on background processes

Is it illogical to relate as follows:
select p.spid
from v$session s, v$process p
where s.paddr = p.addr
I think it get values for the Unix PID of the background process, but I'm beginning to have my doubts.

If you want to get info on the background processes, change your query to:

  select p.spid, b.description
    from v$process p, v$bgprocess b
   where p.addr = b.paddr ;
The spid will be the UNIX process id for the background process.
