Error description

  • On Windows only, the AIO collector EDU doesn't distinguish
    between a failure in the API used to gather AIO operation
    results and a failed AIO operation. On detection of either
    failure it causes an instance panic which results in a shut
    down. For example, asynchronous SMS tablespace writes failing on
    a disk full condition will result in such a reaction by the AIO
    collector EDU.
    
    With this APAR fix DB2 can distinguish between a failed API call
    and a failed AIO operation and will not panic at this point for
    failed AIO operations.
