ISC/IRC Signon activity. If the number of "entries reused" in signon activity is low, and the "entries timed out" value for signon activity is high, the value of the USRDELAY system initialization parameter should be increased. The "average reuse time between entries" gives some indication of the time that could be used for the USRDELAY system initialization parameter.
ISC Persistent verification (PV) activity. If the number of "entries reused" in the PV activity is low, and the "entries timed out" value is high, the PVDELAY system initialization parameter should be increased. The "average reuse time between entries" gives some indication of the time that could be used for the PVDELAY system initialization parameter.
