SLO Support Apparatus for Property Item Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for setting property values in application systems require designers to repeatedly test and revise all settings when only one Service Level Objective (SLO) is not satisfied, making it inefficient to identify and adjust specific property items.
Innovation Solution
The solution involves storing correspondence information that associates standard SLO classification items with property items that impact them, allowing for the specification of property items that need adjustment to satisfy application SLOs, thereby streamlining the process of setting suitable property values.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional techniques list customization items corresponding to an inputted application domain, then the designer can access available components, but the designer must repeatedly test and revise all property values when even one SLO is not satisfied, making the process inefficient
Solution Approach 1:
The invention segments the property items into two categories: those that have an impact on the specified SLO element and those that do not. This segmentation allows the designer to focus only on the relevant property items for testing and adjustment, rather than having to test and revise all property values systematically as in conventional techniques.
Solution Approach 2:
The system performs preliminary action by automatically identifying and presenting only the property items that have an impact on the specified SLO element before the designer begins testing. This preliminary identification step eliminates the need for systematic testing of all property values, saving time and effort.
2Reliability
If the designer tests all property values to ensure all SLOs are satisfied, then complete compliance is achieved, but the process becomes inefficient when only one SLO is not satisfied
Solution Approach 1:
The invention applies partial action by identifying and presenting only the specific property items that have an impact on the not-satisfied SLO element, rather than requiring complete testing of all property values. This partial approach maintains reliability for the specific SLO element in question while significantly improving productivity by avoiding unnecessary testing of unrelated property items.
3Measurement precision
If the system provides detailed correspondence information between SLO classification items and property items, then the precision of property item specification is improved, but the complexity of the system increases
Solution Approach 1:
The system performs preliminary action by pre-storing and organizing the correspondence information between SLO classification items and property items in a structured format. This preliminary organization enables precise specification of property items when needed, while the complexity of maintaining this detailed correspondence information is managed as a background preparation task rather than a runtime complexity.

AI summary
The following solution means are provided for easily specifying property items that have to be revised in order to satisfy a SLO (Service Level Objective): A storage unit (121) for storing an application SLO table that associates a standard SLO item defining a standard SLO with an application SLO item defining a SLO required for executing an application system, and a correspondence table that associates a standard SLO item with a property item having an impact on the standard SLO element. By specifying an application SLO item, a standard SLO item corresponding to that item is extracted from the application SLO table, and a property item corresponding to the extracted standard SLO item is acquired from the correspondence table.
