The display contains the following fields:

- Before-image block size — The BI block size.
- Before-image cluster size — The BI cluster size.
- Number of before-image extents — The number of BI files.
- Before-image log size (kb) — The size of the BI log file, in kilobytes.
- Bytes free in current cluster — The number of free bytes remaining in the current BI cluster.
- Last checkpoint was at — The time of the last checkpoint.
- Number of BI buffers — The number of BI buffers.
- Full buffers — The number of full BI buffers.
