Error description

  • You have put on UK62750. You are still receiving abendAZI9.
    DFHAP0001 AN ABEND (CODE ---/AZI9) HAS OCCURRED AT
     OFFSET X'3042' IN MODULE DFHAPCR.
    
    A CPMI mirror task initiated from WebSphere Message Broker
    over an IPIC connection is purged due to a broker timeout
    while waiting for a response from another mirror task in a
    connected system. The application uses channels and
    containers to transmit data between programs. This results in
    (1) an AZI9 abend at offset x'3042' in DFHAPCR and (2) a
    subsequent SDUMP.  The trace shows the task entering
    the IMPORT_CHANGED function just prior to the task being purged.
    
    Upon review of the dump, DFHZIS2 has issued a DFHPC ABEND AZI9
    while DFHAPCR was attempting to receive the rest of the CHANNEL
    data from the server region. This causes DFHAPCR recovery
    routine to be driven which result in message DFHAP0001 and the
    SDUMP.
    
    The reason why it does not happen all the time is because when
    the TIMEOUT from the client is received in client region,
    the mirror task in that region is an IRLINK wait waiting on the
    response from the server region. The task gets force purged
    by the TIMEOUT resulting in the AZI9 abend and since we are
    not in DFHAPCR, no message DFHAP0001 and SDUMP are produced.

    ****************************************************************
    CICS takes an SDUMP AP0001 if the MRO DPL client task is purged
    when AP domain module DFHAPCR is in the process of waiting for
    a channel response from the DPL server task and a transaction
    abend AZI9 occurs.
    

Problem conclusion

  • DFHAPCR recovery routine is changed to add a check for abend
    code. SDUMP is taken only if the abend code is not 'AZI9'.
