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
