ArcGIS 10.4.1 is a maintenance and quality improvement release. For a list of issues that are fixed in 10.4.1, see the 10.4.1 Issues Addressed List.
The following sections describe changes and new functionality available in ArcGIS 10.4 Data Store.
Changes in terminology
As the number of data store types available with ArcGIS Data Store has grown, it has become necessary to introduce terms to differentiate them. You'll find the following new terms used throughout the ArcGIS Data Store help:
- Relational data store: A relational data store contains hosted feature layer data.
When you create an ArcGIS Data Store relational data store, a managed database is created and registered with the ArcGIS Server site you specify. You then set this ArcGIS Server site as your portal's hosting server to allow members of your portal to publish lightweight, scalable hosted feature layers. The data for the layers is copied into the relational data store at time of publishing.
- Tile cache data store: A tile cache data store contains hosted scene layer tile caches.
Publishing 3D scenes from ArcGIS Pro creates both a hosted scene layer and hosted feature layer. That means 3D scenes require both a relational data store and tile cache data store. Therefore, for convenience, both a relational and a tile cache data store are created when you run the ArcGIS Data Store Configuration wizard.
If your portal members will be publishing many hosted scene layers containing high-resolution tiles, you can use the changenosqldslocation utility to specify another drive on the same server or a shared location on a different server for the tile cache data store location.
- Spatiotemporal big data store: If you use ArcGIS GeoEvent Extension for Server, you can configure a spatiotemporal big data store to archive high-volume observation data. See the next section for more information.
Spatiotemporal big data stores
ArcGIS Data Store has been enhanced to work with observation data through a spatiotemporal big data store. Observation data can include moving objects, changing attributes of stationary sensors, or both. Creating a spatiotemporal big data store allows you to archive high-volume observation data and sustain high-velocity write throughput running across multiple nodes. You access observation data via feature services and visualize it using map services.
You must use the configuredatastore command utility to create a spatiotemporal big data store, not the ArcGIS Data Store Configuration wizard. See the ArcGIS GeoEvent Extension for Server help for more information on working with a spatiotemporal big data store.
Changes to ArcGIS Data Store configuration
When you install ArcGIS 10.4 Data Store, provide credentials for a Windows login to be used for the ArcGIS Data Store account. This allows you to specify a network account that can be granted access to a shared directory you configure for relational data store backup files.
Note:
If you upgrade from ArcGIS 10.3 or 10.3.1 Data Store, you must grant privileges on the content directory and shared backup directory to the account you specify when you reinstall ArcGIS Data Store.
If you configure a standby data store, be sure to use the same login for the standby as you use for the primary data store.
If you need to change the Windows login used for the ArcGIS Data Store account after installation or if the password for the Windows login changes, run the command utility, configureserviceaccount.
In previous releases of ArcGIS Data Store, you had to restart the data store immediately after creating it. You no longer need to do this.
Improvements and changes in ArcGIS Data Store administration
When you configure a standby ArcGIS Data Store, the standby will now include copies of your hosted scene layer tile cache databases (tile cache data store). If the server that stores the primary databases becomes unavailable, your hosted scene layers will failover to use the standby tile caches.
The exportmanageddb and importmanageddb command utilities now allow you to export and import tile cache data stores.
In most cases, though, you should use the new webgisdr tool available with Portal for ArcGIS 10.4 to export and import relational and tile cache data stores. The webgisdr tool exports and imports not just the data but also the web services and portal items that use the data. See What's new in Portal for ArcGIS 10.4 in the Portal for ArcGIS administrator guide for an overview of the tool and links to topics on how to use it.
The default backup schedule and number of days backup files are retained have changed: ArcGIS Data Store creates a full backup every four days and retains seven days' worth of full and incremental backup files. These defaults are set on data stores created at 10.4. Upgrading an existing ArcGIS Data Store does not alter the values already set for that data store.
A new utility—removemachine—allows you to remove a spatiotemporal machine from a data store, or remove a standby relational or tile cache machine from an ArcGIS Data Store installation. Start using the removemachine utility in place of the removestandbymachine utility, which has been deprecated.
