Explanation

The CICS® Listener is defined with a GETTID parameter of YES which indicates that the listener is requested to attempt to obtain the connecting client certificates and user IDs from Application Transparent Transport Layer Security (AT-TLS). If status is DISABLED, then AT-TLS is disabled in the TCP/IP stack. Therefore, the listener is unable to obtain client certificates and user IDs as requested by the GETTID parameter. If status is ENABLED, then AT-TLS has been enabled in the TCP/IP stack, making it possible for the listener to obtain client certificates and user IDs.

mm/dd/yy is the date (month/day/year) of the message.

hh:mm:ss is the time (hours:minutes:seconds) of the message.

transactionid is the name of the listeners CICS transaction.

status is the status of AT-TLS in the TCP/IP stack. status is either DISABLED or ENABLED.

tcpname is the name of the TCP/IP stack.

System action

The listener continues its normal processing, which includes attempting to obtain client certificates and User IDs.

Operator response

Contact the system programmer.

System programmer response

No response is needed if status is ENABLED. If status is DISABLED, then verify that the GETTID parameter of YES is correct in the listener definition. If so, request that your AT-TLS administrator investigate why AT-TLS is not enabled in the TCP/IP stack. See Setting up and configuring CICS TCP/IPSetting up and configuring CICS TCP/IPSetting up and configuring CICS TCP/IP in for a description of the GETTID parameter.

See Application Transparent Transport Layer Security Data Protection in z/OS Communications Server: IP Configuration Guide and Steps for diagnosing AT-TLS problems in z/OS Communications Server: IP Diagnosis Guide for more information.
