Statistics=Import
    Nostatistics

    Specifies that statistic information previously saved by using
    the Statistics=Export qualifier on the RMU Close command is to be
    loaded when the database is opened. The default is Nostatistics,
    which indicates that statistic information is not loaded when the
    database is opened.

    After the database is opened using the Statistics=Import
    qualifier, the saved statistics file is closed. The statistics
    file is not automatically deleted. It can be deleted if it is no
    longer needed.

    When you use the Statistics=Import qualifier, statistics
    information is automatically preserved in the event of abnormal
    database closure. To ensure that the ondisk statistic information
    files are accurate in the case of a node or monitor failure,
    the statistic information files are checkpointed by the database
    monitor every half-hour. The RMU Show Users command identifies
    when the checkpoint for each database occurs.

    The statistic files are not loaded if the physical schema of the
    database has changed since the statistic file was created. This
    means that the addition or deletion of storage aras, logical
    areas, and record caches invalidate the statistic files. This
    restriction prevents incorrect statistic information from being
    loaded when intervening physical changes occur to the database.
    Closing the database updates the statistic files and makes
    them valid. Use the RMU Show Users command to verify that the
    statistic information file was imported.
