IUCV Communication Path

Initiate IUCV communication through the IUCV CONNECT function and terminate it through the IUCV SEVER function. The following rule initiates a one way path connection, letting TLCAMS issue an IUCV CONNECT to communicate with VMSYSU The initiator, TLCAMS, must be specified in the UID of the rule entry; the target, VMSYSU, must be specified as the $KEY value:

RESOURCE
 
SET RESOURCE(IUC)
 
RESOURCE(IUC)
 
COMPILE
ACFCMP510I ACF compiler entered
 
$KEY(VMSYSU) TYPE(IUC)
 UID(*****TLCAMS) ALLOW
 
ACFCMP551I Total record length=144 bytes ‑ 3 percent utilized
 
RESOURCE

Establishing and terminating the IUCV 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 IUCV CONNECT function (to indicate when the IUCV path was initiated) and during the IUCV SEVER function (to indicate when the IUCV path was terminated).
