Classification: Confidential CICS Web Services?
-----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Laurence Chiu Sent: Thursday, December 12, 2024 8:27 PM To: [email protected] Subject: Re: Anybody with experience with CICS Sockets or CICS Sockets Domain? [CAUTION: This Email is from outside the Organization. Unless you trust the sender, Don’t click links or open attachments as it may be a Phishing email, which can steal your Information and compromise your Computer.] 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://arthurvandermerwe.com/2014/06/22/as2805-standards-for-eft/ 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]> wrote: > Are you wanting to write custom protocols, or are you just going to > use HTTP/S?
