Dbkey_Log=file-spec

    Logs the records accessed during a given processing period by the
    various attached processes. The file-spec is the name of the file
    to which all accessed dbkeys are logged.

    The header region of the dbkey log contains four lines. The first
    line indicates that the RMU Show Statistic utility created the
    log file. The second line identifies the database. The third
    line identifies the date and time the dbkey log was created. The
    fourth line is the column heading line.

    The main body of the dbkey log contains six columns. The first
    column contains the dbkey process ID and stream ID. The second
    through sixth columns contain the most recently accessed dbkey
    for a data page, snapshot page, SPAM page, AIP page, and ABM
    page, respectively.

    Only one message per newly accessed dbkey is recorded. However,
    all dbkey values are displayed, even if some of the dbkeys did
    not change.

    The dbkey information is written at the current screen refresh
    rate, determined by the Time qualifier or the Set_rate onscreen
    menu option. Using a larger refresh rate minimizes the size of
    the file but results in a large number of missed dbkey messages.
    Using a smaller refresh rate produces a large log file, but
    contains a much finer granularity of dbkey messages.

    Note that you do not need to display the Dbkey Information screen
    in order to record the dbkey messages to the dbkey log. The
    dbkey log is maintained regardless of which screen, if any, is
    displayed.

    You can use the Dbkey_Log qualifier to construct a dbkey logging
    server, as follows:

    $ RMU/SHOW STATISTICS/NOHISTOGRAM/TIME=1 -
    _$ /NOINTERACTIVE/DBKEY_LOG=DBKEY.LOG MF_PERSONNEL -
    _$ /NOBROADCAST/UNTIL="15:15:00"
