What is the System Request Facility?

The System Request Facility (SRF) provides facilities that let your application programs interface to CA ACF2 for z/VM. You can also use SRF to interface other products to CA ACF2 for z/VM. In many instances, the appropriate place for security validation processing is inside the application program. By using SRF, you can invoke most types of CA ACF2 for z/VM security processing directly from your own application programs. SRF includes the macros and subroutines you need to interface application programs to CA ACF2 for z/VM. In addition, you can use all the other facilities of CA ACF2 for z/VM, such as the databases, ACF subcommands, ACFSERVE commands, and reports.

SRF also includes a comprehensive resource facility that defines logical resources and validates user access to these resources. See the System Programmer’s Guide for more information.
