Patent ID: 8214508

Claim:
A computer-implemented support apparatus for setting property values for property items of an application system, the support apparatus comprising: a storage unit, including a hard drive, configured to store the following: first information that associates, for each of the property items, property item information specifying the property item, and classification item information specifying a first-quality classification item determining a service level to be satisfied by a property value set to the property item, and second information that associates a property item information, a judgment condition for judging whether or not a change in a property value affects a first-quality classification item, and classification item information specifying the first-quality classification item potentially affected by the change in the property value; and a control unit, including a processor, configured to perform the following: receiving, through an input unit, input of third information that associates element information specifying a second-quality element determining a service level to be satisfied by the property values set to the property items, and classification item information, for each second-quality element, and storing the received third information into the storage unit, receiving, through the input unit, input of element information specifying the second-quality element, receiving, through the input unit, input of property item information specifying a property item, and information specifying a property value set to the property item, acquiring, from the second information, the judgment condition corresponding to the property item information inputted through the input unit, and judging whether or not the property value inputted through the input unit affects the first-quality classification item, using the judgment condition, acquiring, from the third information, classification item information corresponding to the element information inputted through the input unit, acquiring, from the first information, the property item information corresponding to the classification item information acquired from the third information, outputting the property item information acquired from the first information, to an output unit, conducting a performance testing after an arbitrary property item is changed to a new property value, judging whether or not an application system satisfies an application Service Level Objective (SLO) based on a result of the performance testing, judging whether or not a previous property value stored in configuration information is unintentionally rewritten, when the application system satisfies the SLO, and displaying whether or not the application system satisfies the application SLO.
