Coupling facility data tables: request statistics

These statistics are described in detail in the DFHCFS8D data area.

Reset characteristics: these statistics are produced by a separate server address space, not by CICS®. Following a reset, these fields are reset by the server, not CICS. As a general rule, high and low watermarks (max, min and highest, lowest) are reset to current, counts are reset to zero.

The individual fields have the following meanings:
