FICON

Use the FICON® statement to enable or disable switch statistics gathering (FICON STATS) on a system.

FICON STATS

If enabled, FICON switch statistics are gathered on each system for all online FICON switches. In a sysplex environment it is not necessary for all systems to gather statistics, and, in fact, doing so might lead to I/O contention issues. If no FICON statement is specified, the system gathers switch statistics by default. To reduce I/O contention at FICON switches, IBM® suggests that when in a sysplex environment FICON switch statistics gathering be disabled on all but one system.

FICON STATS=YES|NO: Specifies whether FICON switch statistics gathering is enabled or disabled on a system.
Tip: If you specify STATS=NO to disable FICON statistics gathering, you might also want to turn off FICON Director Activity Reporting in Resource Measurement Facility™ (RMF™).

Default: Yes
