Does XCOM for z/OS produce type 15 SMF records?
XCOM™ Data Transport® for z/OS
SMF 15 records are written by the z/OS OPEN/CLOSE routines and applications are not responsible for writing them or suppressing them. In that regard, XCOM does not interfere with the producing of SMF 15 records. XCOM uses standard OPEN/CLOSE for all of our datasets.
