If APPLAUDIT is specified, and if AUDIT is specified for the APPL profile associated with APPC/MVS, user verification during APPC/MVS transactions is audited.

Persistent verification (PV) support directly affects the amount of auditing. Without PV support, two SMF records per APPC transaction are produced. With PV support, two SMF records per user are produced: one at signon and one at signoff. The number of SMF records created is reduced.
