Abstract:
1. In association with a configuration management database (CMDB) containing information that relates to configuration items (CIs) in a configurable managed system, wherein a change station is provided to make respective changes, a method for determining whether to allow a particular change that would affect at least a given one of the CIs, said method comprising the steps of: acquiring information from said CMDB pertaining to the given CI that would be affected by said particular change, wherein said acquiring step includes identifying CIs that would be affected by said particular change; selectively processing said acquired information to compute a confidence level indicating the probability that said acquired information is correct based on a time of most recent synchronization of the given CI and a number of reads and writes of the given CI in the CMDB; assigning weights to respective identified CIs, wherein the weight assigned to a given CI represents the probable accuracy of information acquired from said CMDB that pertains to said given CI, wherein said assigned CI weights are respectively processed to compute said confidence level; and allowing said particular change to be made in said configurable system only if said confidence level is no less than a pre-specified minimum value.
