The archiver process are supposed to be ARC0 to 9, so I assummed ARCH (which reports success) was a "generic" message ? ? ?

LOG_ARCHIVE_MAX_PROCESSES is 1 by default (my case) - not sure that 0 is a good value!

Have I missed something ? ? ?
I ran this query and here is what I have

select name, value from v$parameter where name='log_archive_max_processes';
NAME VALUE

log_archive_max_processes 1
