.-CYCLE(1000)-. >>-+-------------+--------------------------------------------->< '-CYCLE(nnnn)-'
Specifies the length of a cycle at the end of which RMF™ samples data, where nnnn is the length in milliseconds. The valid range value is 50 to 9999. If you specify a value outside the valid range, RMF uses 9999 milliseconds for values above the range and 50 milliseconds for values below it.
Sysplex Reporting:
Please use the same CYCLE value for all systems in the sysplex to enable correct sysplex reporting.
The default value is 1000 milliseconds (one second). Decreasing
the CYCLE value to less than one second brings little improvement
in the quality of the statistics produced, compared to the following
adverse effects on performance:
- Increasing the amount of processor time needed to sample data
- Causing RMF to fill the wrap-around storage buffer more quickly
- Using more space in the user-defined VSAM data set
