Error description

  • The abend 5C6-00C94517 is caused during the process of the
    RECOVER CFSTRUCT command.  The command needs to generate a
    structure failed event before recovering the structure
    (the SMDS datasets are in failed status but not the
    structure) this is indicated in message CSQE111I. To do
    this, it calls CSQESTFA that calls CSQIDORF -> CSQIORF1
    with a pointer to an IVSS instead of an expected IVSA.
    
    CSQESTFA finds and passes the IVSS pointer because the
    structure fail event is generated while CSQISCX6 is
    active generating expired message reports for expired
    messages in shared queues located in the structure
    that is being failed.

    ****************************************************************
    A RECOVER CFSTRUCT command performed for a coupling facility
    structure with OFFLOAD(SMDS), with the SMDS dataset in a failed
    state but not the structure, results in message CSQE111I. During
    the recover processing in this scenario abend 5C6-00C94517 is
    issued in CSQIORF1. This is followed by abend 5C6-00C510AD in
    CSQEOCRQ and termination of the queue manager.
    
    In this scenario The recovery processing in CSQIORF1 expects an
    IVSA for a queue object, instead it receives an IVSS for the
    structure, this results in the abends and termination of the
    queue manager.
    

Problem conclusion

  • The recovery processing has been updated to check for a queue
    object before calling CSQIORF1, ensuring the module only gets
    called for the correct object types.
