Statistics_Interval=seconds

    Specifies that statistics are to be displayed at regular
    intervals so that you can evaluate the progress of the unload
    operation.

    The displayed statistics include:

    o  Elapsed time

    o  CPU time

    o  Buffered I/O

    o  Direct I/O

    o  Page faults

    o  Number of records unloaded since the last transaction was
       committed

    o  Number of records unloaded so far in the current transaction

    If the Statistics_Interval qualifier is specified, the seconds
    parameter is required. The minimum value is 1. If the unload
    operation completes successfully before the first time interval
    has passed, you receive only an informational message on the
    number of files unloaded. If the unload operation is unsuccessful
    before the first time interval has passed, you receive error
    messages and statistics on the number of records unloaded.

    At any time during the unload operation, you can press Ctrl/T to
    display the current statistics.
