VMCF Communication Path

Initiate VMCF communication through the VMCF AUTHORIZE function and terminate it through the VMCF UNAUTHORIZE function. The path is controlled in exactly the same way as IUCV communication.

The following rule initiates a one way path connection, letting TLCPJM issue a VMCF AUTHORIZE to communicate with VMTARG. The initiator, TLCPJM, must be specified in the UID of the rule entry; the target, VMTARG, must be specified as the $KEY value:

RESOURCE
 
SET RESOURCE(vmc)
 
RESOURCE(VMC)
 
compile
ACFCMP510I ACF compiler entered
 
$KEY(VMTARG) TYPE(VMC)
 UID(*****TLCPJM) ALLOW
 
ACFCMP551I Total record length=144 bytes ‑ 3 percent utilized
 
RESOURCE

Establishing and terminating the VMCF communication path is logged only if the LOG access permission is specified in the rule entry. If this happens,
CA ACF2 for VM creates an audit record during the VMCF AUTHORIZE function (to indicate when the VMCF path was initiated) and during the VMCF UNAUTHORIZE function (to indicate when the VMCF path was terminated).
