PANUMPOLL is a system parameter that establishes the number of CI and DSSI ports to be polled each polling interval. The normal setting for PANUMPOLL is 16. On systems with less powerful CPUs, the parameter may be useful in applications sensitive to the amount of contiguous time that the system spends at IPL 8. Reducing PANUMPOLL reduces the amount of time spent at IPL 8 during each polling interval, while increasing the number of polling intervals needed to discover new or failed ports. If CI or DSSI devices are not configured on your system, this parameter is ignored. PANUMPOLL is a DYNAMIC parameter.
