FSR—Function Statistics Record

The function statistics record (FSR) is a control block that contains statistics for a particular function that is performed on one data set, or UNIX file (see Table 1). It is maintained in the DFSMShsm work space until the data set, or UNIX file processing has completed. Upon completion of the function, the record is written to the DFSMShsm log and accumulated by category into the daily and volume statistics records in the migration control data set. The control block has a length of 6396 bytes. Only the first 300 bytes are used, unless tape volumes are used for the function, or a UNIX file was processed.

Note: Function Statistics Records relating to UNIX files additionally have the UNIX file name in the FSRDSN field. However, because this field is 44 bytes long, it is possible that the complete UNIX file name cannot fit. In which case, the FSRDSN field contains the first portion of the UNIX file name, followed by ‘...’, and the last portion of the UNIX file name. The complete file name can always be found at the end of the record, after the Tape entries, if any.

When the function statistics record is written to SMF, its first 18 bytes are replaced with the standard 18-byte SMF record header.

Note:

When a DFSMShsm function is executed, only selected fields within the FSR record are set. Which fields are actually set depends on the function being performed and the method that is used to request the function. The fields that are set are required by the DFSMShsm REPORT command.
Function statistics records for ABACKUP and ARECOVER activity can be found in WWFSR—ABACKUP/ARECOVER Function Statistics Record Control Block.
