The Identification and Reconciliation module
provides a centralized framework for identifying and reconciling data from different data
sources. It helps maintain the integrity of the CMDB when multiple data sources such as
EventManagement, Discovery, ImportSets, and ManualEntry are used to create and update CI
The use of multiple sources increases the risk of introducing
inconsistencies through duplicate records. To maintain the integrity of the database, it is
important to correctly identify CIs and services so that new records are created only for CIs
that are truly new to the CMDB. Identification and Reconciliation helps you prevent duplication
of CI records, reconcile CI attributes, reclassify CIs, and allow only authoritative data
sources to update the CMDB.
The identification process is domain aware. If the domain separation plugin has been
activated, then identification processes only those CIs in which the domain ID is identical
to the domain of the currently logged on user. If duplicate CIs exist across domains
(including parent and child domains), then those CIs are not considered duplicate CIs
because their domain IDs do not match.
