HID_CMDB_Reconciliation_Management
We recommend managing ambiguity on a CI by CI basis. In each case, the Configuration Administrator must detect when ambiguity exists and determine the optimal approach. CA SDM takes a broad approach to identify and manage ambiguous CIs that are already in the CMDB.
The
ambiguity index
is an operational measure of the potential non-uniqueness of a configuration item (CI) or a CI transaction item, based on its identifying attributes. The ambiguity index measures the probability of one or more CIs representing the same real business object, or the probability that a CI transaction has more than one possible target CI.
Uses the following process to identify and resolve ambiguous CIs:
  1. Identify ambiguous CIs.
    • Calculate the ambiguity index for all CIs
    • Review the list of ambiguous CIs from the Scoreboard
  2. Determine if the identifying attributes for each CI are valid.
  3. Resolve the ambiguous CI with one of the following actions:
    • Modify the identifying attributes
    • Reject a CI Update by inactivating the CI
    • Supersede a CI
    • Exclude a CI from ambiguity management
Manage Ambiguous CI Transactions
An administrator should review and modify transactions that have ambiguous CI targets before loading the transaction data. You can also resolve CI transactions that do not have a target CI but have identifying attributes for one or more existing CIs. This resolution helps ensure that the appropriate CI is updated and prevents incorrect or inconsistent data from being created.
To view ambiguity either for CIs or CI transactions, you must calculate the ambiguity index by using the cmdb_update_ambiguity utility.
Manage Ambiguous CIs
An administrator should review and resolve the ambiguity between CIs to eliminate incorrect or inconsistent data.
To view ambiguity either for CIs or CI transactions, you must calculate the ambiguity index by using the cmdb_update_ambiguity utility.
Manage Superseded CIs
You can supersede an ambiguous CI so that data is redirected to a specific target CI. You can display superseded CIs, which are Inactive and all web interface updates to them are ignored.
Updates sent to superceded CIs by GRLoader or CMDBf web services are redirected to the superceding CI. However, identifying attributes are ignored.
