Reconciling configuration items

Configuration items (CIs) are reconciled to determine if a newly discovered CI matches a CI that is stored in the TADDM database. This process eliminates duplication in the TADDM database.

Reconciling new data occurs automatically when the following events take place:

• After running a discovery, but before the newly discovered CIs are stored in the TADDM database, the reconciliation process starts. This process eliminates duplicates and cuts down on the overall processing time for discovered CIs. The process is carried out for computer systems discovered by various TADDM sensors and for computer systems loaded from discovery library adapters (DLAs).
• During object storage, the topology manager merges CIs based on matching naming rules.
• Periodically, the topology builder agents run to perform a more complex reconciliation. This method includes the merging of existing CIs, creating relationships, and removing any duplicates CIs not covered by the previous events.
