.-CACHE------------------. >>-+------------------------+---------------------------------->< +-CACHE(SSID(ssid-list))-+ '-NOCACHE----------------'
Specifies cache activity measurement. When you specify CACHE, or allow the default value to take effect, RMF™ gathers activity data for cache control units (there is no support for 3880 control units).
Cache controller data is gathered by individual device address.
There is no indication of which system in the sysplex initiates a
recorded event. Therefore, the data can be gathered on any system
sharing the cached devices.
Note: To avoid unnecessary high CPU utilization
and duplicated data, you should gather cache activity data on one
system only. Refer to "Example that shows how to set up gathering
options" in Generalizing parmlib members, which shows
how to set up gathering options.
To suppress the gathering of cache data, specify NOCACHE.
