Output=file-name

    Specifies a binary statistics file into which the statistics are
    written. Information in the Stall Messages screen is not recorded
    in this file, however. The information in the Stall Messages
    screen is highly dynamic and thus cannot be replayed using the
    Input qualifier.

                                   NOTE

       Statistics from the Stall Messages display are not collected
       in the binary output file.

    For information on the format of the binary output file (which
    changed in Oracle Rdb V6.1), see the Oracle Rdb7 Guide to
    Database Performance and Tuning.
