System logger offloads all the log data to DASD log stream data sets.
For coupling facility log streams, the coupling facility resident data is offloaded to DASD log data sets. Any coupling facility resources allocated for a coupling facility log stream are released. If a coupling facility structure is being shared among multiple log streams, the structure space is re-divided evenly among coupling facility log streams with connected applications at that time.
For DASD-only log streams, the log data in local storage buffers is offloaded to DASD log data sets.
