How Does CA ACF2 for z/VM Work? › User Exits

User Exits

There are two types of installation exits in VM:

• CP‑resident routines
• Service machine resident routines.

This section provides general descriptions of these exit points. You can find complete descriptions of each of the CA ACF2 for z/VM user exits in the Systems Programmer Guide.

CPResident Routines

There are certain installation subroutines that you can add to CA ACF2 for z/VM (at provided exits) that supplement certain routines. The exits are specified in the CP module HCPAC0 by the VMXAOPTS macro, or in the ACF2VM CONFIG file.

The CP‑resident routines are:

• Data set/program prevalidation exit
• Data set/program violation exit
• Data set/program postvalidation exit
• Account prevalidation exit
• Account postvalidation exit
• Unresolved logical device creation exit
• Logon authentication exit.

Service Machine Resident Routines

You can add certain installation subroutines to CA ACF2 for z/VM at provided exits. You must specify these service machine exits in the EXITS VMO record. Each routine must be a self‑contained CMS module.

The service machine resident routines are:

• NEWPXIT (New Password Exit)
• PENCRYP (User Password Encryption Routine).

For more information on these exits, see the Systems Programmer Guide.
