This informational message indicates one or more RACF® TARGET commands were issued that caused RACF to establish this communication link with the partner node using the TCP protocol. On each node, RACF successfully exchanged information, and both agreed to allow the communication. Communication is now considered OPERATIVE ACTIVE between these two nodes. If SYSNAME information is present in this message, the partner node partner-node is a multisystem node.

The cipher (encryption) algorithm cipher was negotiated between the partner nodes using settings defined in the AT-TLS policy. The cipher is being displayed in case you want to monitor (manually or with the use of automation software) connections to double check that the intended encryption was applied, and continues to be applied, by your AT-TLS policy. This information can also be displayed by the TARGET LIST command, and by the Communication Server NETSTAT command. RACF does not enforce a minimum encryption level because some installations might choose to use IPSec for their encryption, therefore, it is important that you must verify the encryption level.
