SMF datasets are named SYS1.MANx, where x is any alphabetic or numeric character (that is, from A through Z, or from 0 through 9). At any one time, a single dataset is the current SMF dataset. SMF uses this dataset, until it becomes full, for recording information.
When the current SMF dataset becomes full, a switch is automatically performed to an empty dataset, which becomes the current dataset, and a message is issued. A message is also issued if no alternate dataset is available.
In response to either message, the operator must dump and clean full datasets so that they can be used again by SMF. Failing to do so can result in losing important system information.
This solution responds to both messages (which means that SMF datasets were switched or that no datasets are available) by initiating a pre-scheduled job in Control-M to dump and clean the full SMF datasets.
