Security Diagnose - Return CA Top Secret Server Userid

The Return CA Top Secret Server Userid function may be used to determine whether CA Top Secret is active in the system, and if so, obtain the VM userid of the server.

The Return CA Top Secret Server Userid function is defined as follows:

• Rx = First (even) register of an even/odd register pair.
• Ry = X'07' subcode

To issue the diagnose function, the user must have access to Diagnose X'A0'. Upon successful completion of the function, condition code 0 will be set, and the specified register pair (Rx,Rx+1) will contain the 8-byte userid of the

CA Top Secret server.

If CA Top Secret has not been initialized since IPL of the CP system, then condition code 1 is set in response to the diagnose function and no registers are modified.

Authorization to execute Return CA Top Secret Server Userid Diagnose does not require ACTION(VMPRIV).
