Error description

  • Customer is using the WSACONTEXT GET interface. When attribute
    EPRTYPE(TOEPR) is coded, there are three scenarios associated
    with IsReferenceParameter that cause ABENDAEXZ.
    .
    1. When IsReferenceParameter starts with capital 'T'
       For example:
    <tag:TagId wsa:IsReferenceParameter="True">xxxxxxxxx</tag:TagId>
    .
    2. When IsReferenceParameter contains child tags
    or child tags contain IsReferenceParameter
             (regardless if case is 'True' or 'true')
       For example:
    <tag:TagId wsa:IsReferenceParameter="true"
                                   xmlns:tag="http://url.xxxx.com">
    </tag:TagId>
    .

    * PROBLEM DESCRIPTION: AEXZ abend after issuing EXEC CICS      *
    *                      WSACONTEXT GET.                         *

    ****************************************************************
    A service requester includes WS-Addressing reference parameters
    in a request to CICS. DFHPIA1 builds an endpoint reference and
    stores it in the DFHADDR-CXT-REQ container.
    If a reference parameter is greater than 255 bytes it is
    truncated but space is allocated for the full length in the
    container. This results in invalid data being saved.
    When an EXEC CICS WSACONTEXT GET EPRTYPE(TOEPR) is issued,
    DFHPIAD extracts the reference parameters from DFHADDR-CXT-REQ.
    Validation of the parameters fails because of the data
    truncation. DFHPIAD returns an ADDRESSING_EXCEPTION and this
    leads to an AEXZ abend.
    

Problem conclusion

  • CICS is changed to prevent truncation of WS-Addressing
    reference parameters sent by a service requester.
