Look at two things

  1. Oracle parameter optimizer_index_caching, increase it to 50
  2. Check the sql queries which are doing lots of buffer gets and tune them
  3. check the query which are doing Index FF scans and check if that is the best way , if yes then increase db_file_multiblock_read_count parameter value.
  4. Check if lots of nested loops joins are happening and check if they are the best access path.
