Writing IUCV Resource Rules

You can initiate IUCV communication using IUCV CONNECT and terminate it with IUCV SEVER. The following rule allows a path connection. TLCPJM can issue an IUCV CONNECT to communicate with TLCAMS. You must specify the initiator, TLCAMS, in the UID of the rule entry. You must specify the target (TLCPJM) as the $KEY value:

$KEY(TLCPJM) TYPE(IUC)
 UID(TLCAMS) ALLOW

Establishing and terminating the IUCV communication path is logged only if you specify the LOG access permission in the rule entry. If this is the case, CA ACF2 for z/VM creates an SMF record during the IUCV CONNECT function (indicating IUCV path initiation) and during the IUCV SEVER function (indicating IUCV path termination).
