This option plays back data as it was collected, using the same sample
intervals. Choose this option to view raw data as it was recorded. This is the
only option available for playing back snapshot data, such as current SQL
statement data and per-process status data. See Table C-2 on page 165 for a
definitive list of the snapshot data items. (They are the ones with "No" in the
"Allowed for Non-raw" column.)
This option is valid only when target is
Historical Server performs no processing on the data. The time of each
playback sample matches exactly the time on the sample from the input
session. The data is exactly the same as in the input session.
Raw playback includes only those recording session samples that fall entirely
between the playback start_time and end_time. For example, if the playback
session start_time is 3 p.m., and an input recording session has 10-minute
samples with one starting at 2:55 p.m., the first sample in the playback is the
one that starts at 3:05 p.m.
If playback start_time is later than the input recording session start time,
cumulative session values are played back as they were collected, with no
adjustments made. For example, if an input recording session started at 1 p.m.,
but the playback start_time is 3 p.m., the data item "Device I/O" "Total for
Session" would reflect the total I/O since 1 p.m.
This option plays back data using the same sample intervals as the input
recording sessions. The playback view can use statistic types different from
those in the recorded data, and it can include some estimated and calculated
data items not in the original view. It cannot include snapshot data, such as
process or lock status data and current SQL statement data. See Table C-2 on
page 165 for a definitive list of data items that can be converted or added to a
playback view.
