Error description

  • Using the MQ API crossing exit CSQCAPX (In CICS 4.1 ) to make an
    MQPUT call within that exit, then return control to CICS, the MQ
    TRUE exit abends at location 000002. Message DFHAP0707 CICSD An
    abend (code 0C1/AKEA) has occurred in task related user exit
    program DFHMQTRU. The problem is that all the MQXCC response
    codes (with the exception of MQXCC_OK which equals 0) are
    negative values (ie MQXCC_SUPPRESS_FUNCTION equals -1;
    MQXCC_SKIP_FUNCTION equals -2 and so on), and for some reason it
    appears that DFHEPC can't handle these if any are set upon
    return from CSQCAPX.

    ****************************************************************
    A CICS/MQ crossing exit program (CSQCAPX) returns an
    ExitResponse of MQXCC_SKIP_FUNCTION and the working storage in
    DFHMQTRU is addressed incorrectly, leading to an S0C1 abend.

Problem conclusion

  • UK49875
    UK52671
    UK52361
    UK55896
    DFHMQTRU has been modified such that, within proc
    execute_api_exit_mqcall_api_exit pointer dfhmqlot.pTrueAstg,
    which is altered prior to calling CSQCAPX, is reset after the
    second call to CSQCAPX only if that call is actually made.
