Error description

  • Environment:
    ITM Universal Agent 622FP5
    
    Problem Description:
    UA Situation w/ MISSING function may produce a false positive.
    The case for the false positive is when UA has a set of data
    rows in its cache and said data rows are NOT missing the
    specific attribute value that MISSING() function is testing for,
    yet the situation fires anyway.
    
    Detailed Recreation Procedure:
    1. Install and configure UA 622FP5 on Windows or *nix system.
    2. Set up an situation for that UA with  MISSING function.
    3. Start that situation,you will find it will be fired one time
    at every startup of this situation, although it doesn't match
    the fired condition.
    

Local fix

Problem summary

  • Situation with MISSING function may product a false positive.
    
    When running a Situation that uses MISSING() function against a
    Universal Agent application where current, monitored attribute
    value(s) is/are not missing, the Situation will incorrectly
    evaluate as true, thus marked as 'open' state.  This behavior is
    most readily observed when stopping and then restarting the
    Situation at a time when attribute at issue is not missing the
    value(s) of interest.
    
    SPECIAL NOTE:  This APAR fix does not prevent a Situation using
    MISSING() function from false positive in case where there are
    no data rows present in memory cache for the associated
    Universal Agent application.  This particular scenario will be
    addressed in a future TEMA release.
    

Problem conclusion

  • Universal Agent data row processing was modified for case of
    situation that contains MISSING() function so that current data
    rows of associated Universal Agent application are always sent
    to the TEMA framework for evaluation by the MISSING() function;
    this design change eliminates the behavior of false positive
    Situations that contain MISSING() function.
