VMMACH Authorization for APPC Connect-Time Security

The VMMACH resource also controls APPC connect-time security on local APPC connection requests.

Permission for an ACID to connect to another virtual machine via APPC is granted as follows:

TSS PERMIT(acid) VMMACH(target) ACCESS(APPC)

Note: In direct response to client requests, this additional APPC security has now been made optional. System security performance will be improved by turning off this feature for those clients that have no need for APPC security.

CA Top Secret is shipped with the APPC security calls disabled. To enable the security, add OPTIONS(1) to start up the Parameter File.
