Calling EGL/cobol from zconnect

  • 1.  Calling EGL/cobol from zconnect

    Posted Thu May 12, 2022 09:09 AM
    hello

    We have recenlty purchased IBM zos connect to bring APIs on our mainframe.
    It works fine but now, we'd like to call our existing EGL/Cobol CICS programs;
    and it always failed  on EXEC CICS ASSIGN TERMCODE  with INVREQ

    Has anyone ever tried zconnect to call EGL ?

    Hi Jean,

    Do you want to call Egl/Cobol from native Cobol Cics or another Egl/Cobol ?
    From Native Cobol you must use EXEC CICS XCTL ... remember when generated Cobol the default transfer commarea is POINTER and nota DATA.

    Hi Hsieh 

    in fact, we need to call EGL/cobol  as a rest API , using IBM zos connect.

    Hi Jean,
    We have done a POC recently to connect EGL Generated COBOL program from Z/OS Connect. 
    Currently we are able to connect with EGL Generated COBOL program through COMMAREA as the interface from ZOS Connect.
    We have prepared a document on it and attaching for your reference. 
    Please go through the document and let us know for any further queries.

    Thanks & Regards,
    Venkata Suresh.

    Thank-you Venkata.

    It is exaclty what i want to do ! 

    We already use a mirror transaction with TWA 1064 (and not 1024 !) to call a EGL  sub-program.

    i will try with   TWA 1024 and let you know.

    Hello Jean-François,
    RBD needs a TWA of 1024. If you have more than this, that is not going to cause  a problem for RBD.

    So i have changed TWA with 1024 , on the mirror transaction, but still get the same error : INVREQ 





    Then the program do an abend ELAE.

    Hi Jean-Francois,

    We are running all our CICS/EGL transactions under TWASIZE 2048. For us 1024 did not work either. 

    Regards

    Hi Jean,

    To understand the error better, we might need to see your code. Without that we wont be able to narrow down the issue. Let us know the feasible time and mode to connect and discuss on the same.
    However, please find below a link which might help to identify the issue.
