When there is an enterprise geodatabase registered with an alphabetical name before "ArcGIS_Data_Store" (Relational), users are unable to query the ArcGIS Data Store logs.

Workaround

When registering a new database connection, ensure the name is listed under "ArcGIS_Data_Store" when ordered alphabetically. For example, name the registered database connection 'GISDATA'.

There is no workaround found for renaming existing portal-linked data store items.

For existing data stores registered via ArcGIS Server Manager or ArcMap, perform the following steps as a workaround:

1. Navigate to ArcGIS Server Administrator Directory and click data > items > / enterpriseDatabases and select the registered database.
2. Rename the registered database, ensuring it is listed below “ArcGIS_Data_Store" when names are ordered alphabetically. In this example, the database connection was renamed to "zAARDVARK".
3. A second database connection with the new name is now be visible in ArcGIS Server.
4. In ArcGIS Server Manager, click Site > Data Stores, and unregister the original database connection. Verify that existing services are not impacted.
