Working with the Reconciliation Analyzer

Reconciliation is the process of identifying and matching entities from different data repositories (for example, UCMDB Universal Discovery, ticketing, or BSM). This process is designed to avoid duplicate CIs in UCMDB. For detailed information about the reconciliation process, see "Reconciliation" in the Data Flow Management section in the UCMDB Help.

The Reconciliation Analyzer helps you understand how the reconciliation process works. By using this option, you can find what happened with a CI that may have merged with another CI. You can view the following information:

• All the changes made to the searched CI (create, update, or remove CI)
• The reasons why the CI was changed. This includes a list of identification candidates, and the reasons for matching the searched CI with them

The changes are listed in chronological order, grouped by reconciliation Operations. The most recent operation is displayed on top of the page. You can view the following information for each reconciliation operation:

• The type of operation performed: created, modified, or removed
• The date and time when the operation was performed
• A list of changed attributes. For each changed attribute you can view the attribute name, the previous value of the CI attribute (before the change), and its new value.

If some reconciliation operations are performed and the CI is not changed, then those operations will not be displayed the Reconciliation Analyzer module.
