Hi,
I have a standalone DB of version 10.2.04.I am facing log file parallel write 
as one of the top events.
I have increased the REDO log file size to 500m.But even then REDO switching is 
happening frequently.
select group#, bytes, archived, status, first_change#, first_time from v$log 
order BY first_change#;
    GROUP#      BYTES ARC STATUS           FIRST_CHANGE# FIRST_TIME
---------- ---------- --- ---------------- ------------- ----------
        10  262144000 NO  INACTIVE               8509999 30-08-2012
        12  524288000 NO  INACTIVE               8612142 30-08-2012
        11  262144000 NO  INACTIVE               8676390 30-08-2012
