Does CA XCOM for z/OS produce type 15 SMF records?
z/OSXCOM r11.6 or XCOM r12.0
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.
