DCMT DISPLAY STATISTICS Command

The DCMT DISPLAY STATISTICS command displays:

The interval at which statistics are written to the log file.
The interval at which statistics are written to the log file and rolled out.
Current DC/UCF system statistics.
Specific statistics on database page reads and writes for areas, buffers, and files.
The number of times a read request was fulfilled by a page that was already in the buffer. No I/O occurs for this type of read request.

DC/UCF gathers the statistics from active control blocks, not from the system log.
