APF authorization

To permanently authorize the z/OS® DLA for APF (Authorized Program Facility) authorization from an MVS TSO session, complete these steps (which require an IPL, but eliminates the requirement to re-authorize after every IPL):

1. Add an entry to the PROG01 data set member (typically found in USER.PARMLIB):

   SETPROG APF,ADD,DSNAME(&DLAHLQ.SIZDLOAD) SMS

2. Execute an IPL on the z/OS LPAR by using local procedures.
   Follow these steps to temporarily APF-authorize the z/OS DLA from an MVS TSO session (which remain in effect until you execute another IPL):

   =S.LOG
   /
   SETPROG APF,FORMAT=DYNAMIC Set APF format dynamic
   and
   SETPROG APF,ADD,DSN=<DLAHLQ>.SIZDLOAD,SMS
   D PROG,APF,ALL Confirm which DSNs are APF-authorized

   You must issue an APF authorization command for z/OS DLA to run.
