Error description

  • The response returned for a Web Service Proxy service contains
    two SOAP envelopes with the fault information when all the
    following are true:
    
    - Probe is enabled.
    - Web Service Management (WSM) is enabled.
    - Web Services Management Agent's Buffer Mode is set to Buffer.
    - An error occurs during multi-step.
    
    The following is an example of a correct response:
    
    <soapenv:Envelope
    xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" >
        <soapenv:Body>
            <soapenv:Fault>
                <faultcode>0x03</faultcode>
                <faultstring>service error (TID
    4987687)</faultstring>
            </soapenv:Fault>
        </soapenv:Body>
    </soapenv:Envelope>
    
    The following is an example of a response returned where there
    is a double SOAP envelope with the fault information.
    
    <?xml version="1.0" encoding="UTF-8"?>
    <soapenv:Envelope
    xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
    <soapenv:Body>
    <soapenv:Fault><faultcode>0x04</faultcode>
    <faultstring>service error (TID 6401841)</faultstring>
    </soapenv:Fault>
    </soapenv:Body>
    </soapenv:Envelope>
    <?xml version="1.0" encoding="UTF-8"?>
    <soapenv:Envelope
    xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/">
    <soapenv:Body>
    <soapenv:Fault><faultcode>0x04</faultcode>
    <faultstring>service error (TID 6401841)</faultstring>
    </soapenv:Fault>
    </soapenv:Body>
    </soapenv:Envelope>
    

Local fix

  • Use one of the following:
    
    1) disable Probe.
    2) set WSM Agent's Buffer Mode to "Discard". Note: Buffer mode
    is the recommended setting so only use this as a temporary
    workaround.
    3) disable WSM Agent.
    

Problem summary

  • Affected is the use of Probe with Web Service Management
    (WSM) for a Web Service Proxy (WSP).
    
    If WSM is in "Buffer" mode, then a WSP SOAP response message
    is returned twice to the client.
    

Problem conclusion

Temporary fix
