Abstract

A method is provided for assigning weights to configuration items (CIs) in a configurable managed system, wherein respective weights are derived from information contained in an associated configuration management database. The information could include without limitation the relationships that a configuration item (CI) has with other CIs and the number of reads and writes that are made between the CI and other CIs. A Change Manager in the configurable system makes changes affecting CIs, wherein different types of changes require different levels of confidence in the integrity of data in the CMDB. Accordingly, the weights of respective CIs are used to provide a confidence level regarding the accuracy of CMDB data, pertinent to a proposed change. The confidence level is then used by the Change Manager in deciding whether or not to make the change. One embodiment comprises acquiring information from the CMDB pertaining to CIs that would be affected by a particular change, and processing the acquired information to compute a confidence level indicating the probability that the acquired information is correct. The particular change is then allowed only if the confidence level is no less than a pre-specified minimum value.
