Error description

  • You are running CICS Transaction server 4.1 under z/OS 1.11
    with PK95579 / UK52681 applied and you receive ABENDAXFV.
    DFHDU0201  ABOUT TO TAKE SDUMP. DUMPCODE: AXFV
    Transaction CSNE was in control, handling a losterm error
    condition.  The node error program- DFHZNEP issued an
    exec cics start to a remote region which caused the ABENDAXFV
    to occur.
    In another example, transaction CPLT was running issuing a
    READ to a remote file, which also caused the AXFV abend.
    Code in module DFHXFX is calling DFHUSAD to process
    USAD_INQUIRE_ICRX.  The first thing DFHUSAD does it to
    inquire on the US token for the task. In this case it was
    zero- due to being a system task, causing it to set
    RESPONSE  02 - USAD_EXCEPTION
    REASON    1F - USAD_INVALID_USER_TOKEN
    This causes DFHXFX to abend the task AXFV.
    .
    Additional symptoms:  IDPROP ID propragation

    ****************************************************************
    A task function ships a request to a remote system over an MRO
    link. As part of processing for the request CICS module DFHXFX
    issues a DFHUSAD INQUIRE_ICRX call to find out if the task has
    an ICRX and if so how large it is. DFHUSAD attempts to locate
    the ICRX for the task from its user token. However some tasks
    don't have a user token. The INQUIRE_ICRX call fails with
    response USAD_EXCEPTION, reason USAD_INVALID_USER_TOKEN, causing
    DFHXFX to abend the task AXFV. The failing DFHUSAD INQUIRE_ICRX
    call was added to DFHXFX by APAR PK95579.
    .
    Additional symptoms:  IDPROP ID propagation ABENDAXFV
    

Problem conclusion

  • UK52681
    .
    DFHUSAD INQUIRE_ICRX processing has been changed to return
    USAD_EXCEPTION with reason USAD_ICRX_NOT_AVAILABLE if the user
    token is zero.
