Some programs or applications which use ICSF require that the environment be program controlled. In a program controlled environment, programs within the address space are defined to the Security Server (RACF). Defining a program to RACF requires the program name and the name of the data set which contains the program.

The commands to define the ICSF load module to RACF are:

RDEFINE PROGRAM * ADDMEM('CSF.SCSFMOD0'//NOPADCHK) UACC(READ)
SETROPTS WHEN(PROGRAM) REFRESH

Additional details on program control may be found in the "Program Control" topic of the z/OS Security Server RACF Security Administrator’s Guide.
