TN3270 should provide a Display command on the Cached Certificate

TN3270 caches the CERT when it is started.  There is no way to identified what the name of the CERT is that is cached. Or when it will expire.  It would be helpful to be able to issue a DISPLAY Command (MVS Command) to request the name of the CERT and Expiration date of the CERT.  This would allow a shop to automate notification of expiration of a cert.  Or to be able to easily identify a cert issue.

Currently an SVC Dump of the GSKSRVR task is the only way to identify the cert that is cache

    The need to understand which certificates are being used by a given server on z/OS is not limited to the TN3270E server. Rather, it is a universal need. There are already RACF commands you can use to list the contents of a given server?s keyring (RACDCERT LISTRING) as well as the contents of the certificates (RACDCERT LIST) and even the trust chain for a given certificate (RACDCERT LISTCHAIN). All you need to know is the name of the keyring that your server is using, which is something that needs to be configured for the server (in the case of the TN3270 server, it needs to be coded in the AT-TLS rule protecting the TN3270 server port). We suggest you use these commands or commands like them if you are using ACF2 or TSS as your ESM.
