   Action
      Investigate the possibility of improving the performance of I/O to the
      online redo log files.
   Rationale
      The average size of writes to the online redo log files was 10 K and the
      average time per write was 7 milliseconds.
   Rationale
      The total I/O throughput on redo log files was 0 K per second for reads
      and 947 K per second for writes.
   Rationale
      The redo log I/O throughput was divided as follows: 0% by RMAN and
      recovery, 100% by Log Writer, 0% by Archiver, 0% by Streams AQ and 0% by
      all other activity.
