Changing the tile cache data store mode in ArcGIS Enterprise from cluster mode to primary-standby mode or from primary-standby mode to cluster mode causes existing scene services to become broken and returns the error message, "Scene service is missing root node."

Workaround

When receiving the error message, "Scene service is missing root node" with the tile cache data store in cluster mode, backup the tile cache data store, unregister, and restore it with the mode in primary-standby:

1. Back up relational and tile cache data stores:

• For tileCache, a backup location must be configured: configurebackuplocation --operation register --store tileCache --location <file location>
• backupdatastore <name of backup file> --store tileCache

2. Stop the ArcGIS Data Store service, delete all folders in C:\arcgisdatastore (or reinstall data store).

3. Unregister data stores within ArcGIS Server Manager> Site > Data Stores.

4. Start the ArcGIS Data Store service, restore data store.

• restoredatastore --store tileCache --target <name of backup file> --source-loc <file location> --data-dir C:\arcgisdatastore --server-url <https://fqdn:6443>; --server-admin <username> --server-password <password> --mode primaryStandby

5. Run describedatastore to verify the mode has changed to primary-standby mode and validate data stores within ArcGIS Server Manager. Existing scene services now load as expected without the error message, "Scene service is missing root node" in Scene Viewer.
