Transfers via SFTP to External Mainframe Application (Vendor : DTCC)

IBM Team,

We have currently are transfer files to our external vendor DTCC mainframe application via Connect Direct protocol. DTCC has changed the requirement to transfer via SFTP instead of Connect Direct to their mainframe end point. 

How can the parameters such as Record Length, DCB parameters and secure+ integrated with SFTP transfer? Is this something which can be enchanced via SFTP transfer?

    Thank you for taking the time to provide your ideas to IBM. We truly value our relationship with you and appreciate your willingness to share details about your experience, your recommendations, and ideas.


    IBM has evaluated the request and has determined that it cannot be implemented at this time or does not align with our current strategy or roadmap.


    The specified parameters (Record Length, DCB parameters and secure+) are custom parameters with some being Connect:Direct mainframe parameters. Sending these parameters from the client to an SFTP server means that there needs to be something on the server side that knows what to do with these parameters.


    Custom parameters are not part of the SFTP standard, which is what we follow in our SFTP implementation in SFG. We adhere to the SFTP RFC to ensure interoperability, and adding this would deviate from the SFTP standard and potentially break other customers using SFTP.


    SFG is a distributed application not intended to emulate the mainframe. We cannot make it invisible to customers who are migrating off of mainframe to use distributed - they are different worlds with different architectures and requirements.


    There may be customizations done by DTCC and their trading partners who are using SFTP to handle this case, but this is outside the scope of what SFG was designed to do. Our recommendation would be to work with DTCC on emulating what their trading partners are doing with transfers over SFTP.


    Thank you for bringing your ideas to us. If you have any additional feedback, thoughts or ideas, or if there is anything else I can do, please do not hesitate to reply to this message to continue the conversation.

    Thank you for taking the time to provide your ideas to IBM. I truly value our relationship with you and appreciate your willingness to share details about your experience, your recommendations and ideas.

    I need a little more information to understand your idea.

    • We have been working with DTCC on SFTP server enhancements over the last year to address this modernization project in a way that is as transparent to trading partners as possible

    • We have not received any requests from DTCC to adjust the SFTP client side so far

    • What are the commands you are using and the specific custom parameters that need to be sent?


    Our recommendation would be to work with DTCC on how they are implementing the change from C:D to SFTP and what is expected from the trading partner / SFTP client side in order to continue to exchange files with DTCC as there may have been other enhancements being done on their side that we do not know about.


    I'm looking forward to your response. Once I can develop a clear picture of your request, I'll be able to let you know if we can add your idea to our future offering roadmap.
