You can assign a connection to one or more catalog sources.
To assign or unassign specific connections to objects in the catalog source, ensure that you define appropriate roles and select the Manage Connection Assignments feature for that role when configuring privileges for Metadata Command Center in Informatica Intelligent Cloud Services Administrator. For more information about feature privileges that the organization administrator can configure for user roles, see the Introduction and Getting Started help.
1On the Configure page, select the Lineage tab, and then select the Lineage Discovery tab.
2On the Catalog Sources panel, select the required catalog source.
You can filter the list by catalog source type or recommendations.
Catalog sources with CLAIRE recommendations are represented with a thunderbolt icon on the Catalog Sources panel.
3Click the Assign Connections tab.
The Assign Connections tab displays a list of assigned and unassigned connections along with details for each connection. On the Assign Connections tab, use filters to view the connections based on the connection names. Click the Add Filter menu to add filters.
Based on the catalog source you select on the Catalog Sources panel, the Related Catalog Sources tab displays a list of related catalog sources.
4On the Assign Connections tab, select the connection to the reference source system and click Assign.
The connection name appears prefixed to the reference catalog source name on the Hierarchy tab of your catalog source in Data Governance and Catalog.
The Assign Connection dialog box appears with a list of recommended objects from the endpoint catalog sources. Click All to view all endpoint catalog source objects.
5In the Assign Connection dialog box, select one or more objects from the endpoint catalog sources and click Assign.
You can filter the list in the Assign Connection dialog box by name, type, or endpoint.
6To view CLAIRE recommended endpoint objects, click Recommended.
To view all the endpoint objects, click All.
7Select or clear the Case Sensitive option to determine whether you want the endpoint object name to be considered as case insensitive during the object matching process between the connected source systems.
8Click Assign.
If your catalog source uses connection-aware scans, run the catalog source job again. If you configured the catalog source job to run on a regular schedule, the next scheduled run picks up the updated details. If you didn't configure a schedule, run the catalog source job again to view complete lineage.
When you click Assign, Metadata Command Center creates links between matching objects in the connected catalog sources, and it calculates the percentage of matched and unmatched objects. The higher the percentage of matched objects, the more accurate the lineage that you view in Data Governance and Catalog.
Note: If you run the catalog source sync job after assigning the connections, the CatalogMergeOperationTask is triggered. If this task fails or completes with errors during the catalog source sync job, then all the previously assigned connections to that catalog source are removed and its status changes to unassigned. You can then assign connections to that catalog source on the Monitor page as described in the steps above.
9For catalog sources with lineage discovery enabled and CLAIRE recommendations, select the connection and click Accept Recommendation or Reject Recommendation from the Action menu.
You can view CLAIRE recommendations for a catalog source if run with the lineage discovery capability.
If there are multiple CLAIRE recommendations, you can click the Multiple link available on the Endpoint, Endpoint Type, or Catalog Source Type properties, and accept or reject the CLAIRE recommendations in the Catalog Sources dialog box.
After you accept the CLAIRE recommendation, the connection assignment job starts. You can check the status of the job on the Monitor page.
