Create a data refresh rule for a non-CMDB table

To apply Identification and Reconciliation Engine (IRE) features to supported non-CMDB tables, create data refresh rules for those tables. Data refresh rules are used to determine if a record is stale for a specific data source. Such records can then be updated by a lower-priority authorized data source.

Data refresh rules have no impact when dynamic reconciliation rules are in effect.

Data refresh rules are used in conjunction with static reconciliation rules to determine reconciliation steps for a record. These rules determine if, when, and by which data source a record can be updated.

手順

1. Click All.
2. In the Filter navigator, enter cmdb_datasource_staleness.list to open the Data Source Staleness Definitions table.
3. In the Data Source Staleness Definitions list view, click New.
4. Fill out the Data Source Staleness Definitions form.

   Field	Description
   Applies to	Non-CMDB class that this rule applies to.
   Data source	Data source for which record staleness is evaluated.
   Effective Duration	The time period that is used for the staleness evaluation. If the fields specified in the static reconciliation rule for the record's class were not updated by the specified data source within the specified time period — the record is determined to be stale for that data source. If you enter a value with a prefix that is valid and a suffix that is not, such as 15 x — the valid portion of the value is used ('15'). If the entire value is invalid — the default value of 0 is used.
   Active	Activates the rule.

5. Click Submit.
