APAR status

  • Closed as program error.

Error description

  • Both CICS and CPSM can make calls to the CICS RS Domain in
    order to update region status information. If the call to the
    RS Domain code was made by CPSM and an error occurs,
    CPSM-relevant diagnostics are not produced. This APAR is being
    opened to address that issue and produce the diagnostic
    messages and dump needed for problem resolution.

    * PROBLEM DESCRIPTION: CPSM dataspaces are not dumped when     *
    *                      DFHRSSR abends when called by CPSM      *
    *                      WLM.                                    *
    ****************************************************************
    * RECOMMENDATION: After applying the PTF that resolves this    *
    *                 APAR, all CMASes and MASes must be           *
    *                 restarted.  Note that the restarts do not    *
    *                 need to occur at the same time.              *
    ****************************************************************
    Module DFHRSSR is called in a CMAS or MAS to perform processing
    related to CPSM WLM.  The caller may be CICS or CPSM.  If an
    abend occurs within DFHRSSR, message DFHRS0001 is issued and
    CICS will take a dump.  While this processing is sufficient if
    CICS is the caller, it is not sufficient if CPSM is the caller,
    as the dump will not contain the CPSM dataspaces.
    
    DFHRSSR abend recovery processing will be changed to call CPSM
    services to provide CPSM abend diagnostic messages (EYUXL09xx)
    and a CPSM dump if the caller of DFHRSSR is CPSM.  If the caller
    of DFHRSSR is not CPSM, then message DFHRS0001 and a CICS dump
    will continue to be provided.
    

Problem conclusion

  • DFHRSSR abend recovery has been updated to call new module
    EYU9XLRS. EYU9XLRS will determine if the caller was CPSM, and if
    so, will retrieve the abend information from the CICS Kernel
    error block, and call module EYU9XLRV.  EYU9XLRV will call
    module EYU9XLRW to produce the CPSM abend diagnostic messages
    and then will request a CPSM dump.  The title of the dump will
    be similar to the following:
    
      EYU9XLRV Dump,<jobname>,<cpsmname>,<lpar>,<CMAS|LMAS>,
      <tranid>,<tasknum>,<abendcode>,DFHRSSR,<date>,<time>
    
    EYU9XLRV will then return to EYU9XLRS, which will return to
    DFHRSSR recovery processing, which will bypass the DFHRS0001
    message and the CICS dump.
