Aging

Aging is a mechanism used to delete obsolete core UCMDB CIs and relationships. Unused CIs add overhead to the CMS performance. Every CI in the UCMDB consumes server CPU, memory, and database resources.

Whenever the CI is touched by a discovery job, the Last Scan Date property is updated, so the deletion time is deferred.

Aging Setting at Adapter Level

You have full control of the aging parameter for all CI types based on the discovery jobs. Adapter settings will have a Results Management section which can guide you to set the appropriate aging setting for discovered CI types.

Aging

DB Tool: The DB Tool can be used for a mass deletion of aged CIs and relationships. It deletes the CIs in batch mode, and requires server shutdown. It writes log messages to db.tool.log.

Usage: <UCMDB_Server_Home>\tools\dbscripts\dbtool.bat aging
