Raw playback

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. Also, 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 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 client.

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.
