Abstract

A system, method, and medium for providing configurable item configuration data by receiving a plurality of configuration data sets from a plurality of sources, all which pertain to the same configurable item (CI), then using weighting rules and preferences to assign weight values for each option, feature, and component in each report according to discrepancies and commonalities between the data sets, creating a new data set for the configurable item by selecting options, features, and components having the greatest weight values among all of the data sets, assigning confidence factors to each option, feature, and component by weight comparisons between the plurality of data sets; updating a configuration management database entry for the configurable item accordingly. The confidence factors are useful for inhibiting regulated processes, such as software release processes and change control processes, and for generating human-readable configuration reports indicating confidence levels of the reports and their contents.

Claims

1. A method for resolving conflicting details in configuration reports comprising:

receiving by a computer a plurality of configuration reports, the received reports reflecting configuration states or configuration state changes about a single configurable item, the configurable item having a plurality of reported configurable elements, the configuration reports being received from a plurality of different sources and being of unknown correctness regarding actual states of the single configurable item and its one or more installed elements;

assigning by a computer a weight value to each reported single configurable element which conflicts with another reported single configurable element in the configuration reports using one or more computer-based weighting rules, wherein the rules comprise a determination of a likelihood of correctness of each conflicting reported element actually being present and enabled in the configurable item, and wherein the conflict comprises at least one element detail selected from the group consisting of revision level, version level, patch level, capacity, license status, age, percentage of capacity used, percentage of capacity unused, installation date, and removal date, and excluding operational fault status;

resolving by a computer each conflict by selecting by a computer only one of each of the conflicting elements having greater assigned likelihood of correctness weight values and preferences; and

creating by a computer a new configuration report for the selected single configurable item by producing a report containing only the single selected configurable elements having the greater likelihood of being present and enabled in the configurable item, and omitting non-selected configurable elements.

2. The method as set forth in claim 1 further comprising generating a configurable item unit-level confidence factor based upon said confidence factors of said configurable elements.

3. The method as set forth in claim 2 further comprising employing said unit-level confidence factor in a regulated process control such that said regulated process is inhibited for configurable items having unit-level confidence levels below a threshold value.

24. The system as set forth in claim 4 further wherein said evaluator generates a configurable item unit-level confidence factor based upon said confidence factors of said configurable elements.

25. The system as set forth in claim 24 wherein said unit-level confidence factor is employed in a regulated process control such that said regulated process is inhibited for configurable items having unit-level confidence levels below a threshold value.

12. A computer program product for resolving conflicting details in configuration reports comprising:

assign a weight value to each reported single configurable element which conflicts with another reported single configurable element in the configuration reports using one or more computer-based weighting rules, wherein the rules comprise a determination of a likelihood of correctness of each conflicting reported element actually being present and enabled in the configurable item, and wherein the conflict comprises at least one element detail selected from the group consisting of revision level, version level, patch level, capacity, license status, age, percentage of capacity used, percentage of capacity unused, installation date, and removal date, and excluding operational fault status;

resolve each conflict by selecting only one of each of the conflicting elements having greater assigned likelihood of correctness weight values and preferences; and

create a new configuration report for the selected single configurable item by producing a report containing only the single selected configurable elements having the greater likelihood of being present and enabled in the configurable item, and omitting non-selected configurable elements.
