Just a thought, but is it an option to reroute the AS2805 data via MQ from your public gateway into the z/OS system(s) where the CICS regions live? If so then you could just use MQ triggering in CICS to start drainer transactions to process/distribute the incoming MQ messages. The AS2805 data could just be delivered in an MQ envelope.
Not sure what the TCO of that would be, as I don’t know the pricing structure of the MQ pieces to accomplish that from a public gateway inwards to CICS (and possibly outbound again?).

This is the situation as I understand it. We have a mainframe program (not CICS) that communicates with a CICS region using Enterprise Extender The code that enables this is vendor provided so we don't have much visibility of how that works, On the CICS side there are a number of terminals defined that invoke defined CICS transactions when traffic arrives from that mainframe program. This pattern is being replaced by external messages coming in at our public gateway in AS2805 format, that need to be routed to the CICS region. https://urldefense.com/v3/__https://arthurvandermerwe.com/2014/06/22/as2805-standards-for-eft/__;!!Ebr-cpPeAnfNniQ8HSAI-g_K5b7VKg!L-pNNj67ZbrBRTrC60iQYKITf93yNQvhuTsCOViMKsBZ-XVY9wW9wlj00MG888X5-tPSm_qN-DQ9et8s3zaVbbxK4As1U25ohKdCBGA0$<https://urldefense.com/v3/__https:/arthurvandermerwe.com/2014/06/22/as2805-standards-for-eft/__;!!Ebr-cpPeAnfNniQ8HSAI-g_K5b7VKg!L-pNNj67ZbrBRTrC60iQYKITf93yNQvhuTsCOViMKsBZ-XVY9wW9wlj00MG888X5-tPSm_qN-DQ9et8s3zaVbbxK4As1U25ohKdCBGA0$> So it seems like we need to write some CICS Socket code to receive and process that traffic. And based on my limited research to date, since the traffic is not in a standard protocol like http, sftp etc. we cannot use CICS Socket Domain but have to use CICS Sockets, On Fri, Dec 13, 2024 at 12:04 PM Frank Swarbrick < [email protected]<mailto:[email protected]>> wrote: > Are you wanting to write custom protocols, or are you just going to use > HTTP/S?
