Pinned topic Modernizing LU6.2 CICS application question

‏2008-02-15T09:52:42Z |
Hi,
This is Demet Tanju from IBM Turkey.
Is there a way to talk to existing LU 6.2 CICS appl. (formerly from AS/400
to CICS LU 6.2) from a Websphere z/OS appl. without a change to the legacy
CICS application?

Best regards

    You should be able to, but it will require changing the AS/400 side.

    We had LU6.2 client/server application where the client was C++
    application using CICS Universal Client.

    We re-write part of the client code to use HTTP to talk to Websphere
    z/OS and Websphere used CICS Transaction Gateway to talk to CICS.

    There were no required changes to the CICS applications, only new code
    in Websphere and new code on the client side.
