Control files are all always active AFAIK, hence the 'control file parallel write' event.

This query will show you which log files are active:

set line 120

col member format a40 head 'MEMBER'
col group# format 99 head 'GRP'
col thread# format 99 head 'THR'
col sequence# format 999999 head 'SEQ'
col group_status format a8 head 'GROUP|STATUS' col member_status head 'MEMBER|STATUS'
col systime format a18 head 'SYSTEM TIME' col bytes format 99,999,999,999 head 'SIZE IN BYTES' col first_time format a20 head 'TIME OF FIRST SCN' col archived head 'ARCHIVED?' format a10

clear break
break on group# skip 1

select

l.group#,

thread not needed unless OPS --thread#, sequence#, bytes, member, l.status group_status, f.status member_status, l.archived, first_time from v$log l, v$logfile f where l.group# = f.group# order by group#, thread# /

Is there a way of knowing while db is up which: conrtolfile or redo logfile is active? and if multiplex when does it switch?
