Changed and new fields of the Device Activity report: DEVICE ACTIVITY RATE .... This formula applies to the activity rate measured during asynchronous I/O processing. ... A character S appended to the DEVICE ACTIVITY RATE value of a device shown in the Direct Access Device Activity report indicates that the device performed synchronous I/O requests and that detailed synchronous I/O performance measurements for this device are available in the Synchronous I/O Device Activity report section. For easy comparison the Synchronous I/O Device Activity report lists the asynchronous I/O device activity rate (ASYNCH I/O) in adjacent columns showing - the rate of successfully completed SYNCH I/O READ requests - the rate of SYNCH I/O WRITE requests which completed successfully during the interval. The synchronous I/O activity rate is calculated as #Successful Synch I/O read/write requests ACTV RATE = ----------------------------------------- Interval Time AVG RESP TIME The average number of milliseconds the device required to complete an asynchronous I/O request. ...
