Controlling the frequency of SMF z/OS catalog queries

To determine if any new, unread data sets match the specified SMF_DSN_MASK_x values, the SMF processing address space (AUIFSTC) periodically performs a query against the z/OS catalog, looking for data sets to process. By default, this query is performed when the AUIFSTC task is started, and repeated every 300 minutes (5 hours). To change the default time value, use the keyword SMF_CYCLE_INTERVAL(time in minutes). If you specify a time value of zero, the SMF auditing feature will be disabled.
