Error description

  • CICS is processing an inbound SOAP request when this problem
    happens. The problem requires a SOAP header handler program be
    active and for a context switch to take place. During the
    SEND-RESPONSE phase of the PIPELINE, the SOAP header handler
    program has to issue EXEC CICS SOAPFAULT CREATE. This causes
    DFHPISN to drive the header programs again for HANDLER-ERROR.
    DFHPISH is called to manage this process. However, its list of
    programs to call was freed at the end of the SEND-RESPONSE
    phase and so it needs to be reconstructed. This process
    requires the data from the DFHPARSE-OUTPUT container. The SET
    data for the container has been freed when the container got
    re-imported after running the user task. Depending on whether
    the SET storage got reused will effect the error that occurs
    in DFHPISN.
    Looking at trace for this problem, this is what it shows:

    ****************************************************************
    A provider PIPELINE with at least 1 SOAP header handler is
    installed in CICS.  A SOAP message is received by CICS and
    passed to this PIPELINE for processing.
    
    DFHPISN parses the SOAP message and the output from the
    parser is placed in the DFHPARSE-OUTPUT container.  DFHPISN
    accesses the output using GET CONTAINER SET.  References to
    data within this SET area are kept in the PISN block for this
    request.
    
    DFHPISH is called to invoke the header handler programs.  To do
    this a program_list structure is created using information from
    the PISN block, which ultimately refers to the DFHPARSE-OUTPUT
    SET buffer.
    
    One of the handler programs has caused a context switch to
    occur.  This means that the apphandler (DFHPITP) runs in a
    separate task managed by request streams.  This process causes
    the current channel to be exported and sent to the new task.
    On completion the original containers on the channel are
    deleted and a the updated channel is imported.  During the
    deletion process the DFHPARSE-OUTPUT SET buffer was freemained.
    
    DFHPISH is called to invoke the header handler programs again.
    It uses the program_list structure created earlier.  One of the
    header handler programs generates a SOAP Fault.  When DFHPISH
    completes, the program_list structure is deleted.
    
    Due to the SOAP Fault being created, DFHPISH is called again
    so that the header programs can be notified of the error.  The
    program_list structure was deleted so a new one is required.
    This is built using the PISN block for this request which still
    contains references to data in the DFHPARSE-OUTPUT SET buffer.
    This buffer doesn't exist any more.  The results are
    unpredictable and depend on whether the area of storage has
    been reused or not.  In this case a DFHPI0002 message and dump
    were issued.
    

Problem conclusion

  • DFHPISH has been changed to no longer delete the program_list
    structure.
    
    DFHPISN has been changed to delete the program_list structure
    on completion of processing the SOAP request.  It has also been
    changed to use GET CONTAINER INTO instead of GET CONTAINER SET
    when retrieving the DFHPARSE-OUTPUT container data.  This allows
    the storage area to persist for the lifetime of DFHPISN.
