Technology changes that impact ArcGIS Data Store 11.5 include a change in graph store modes and the deprecation of the tile cache data store. These changes and additional new or altered ArcGIS Data Store functionality are described in the sections below.
Changes to graph store modes
The underlying technology no longer supports primary-standby mode. For this reason, the graph store must be deployed in single machine or a three-machine cluster mode starting with 11.5.
Moving to a three-machine cluster mode also provides greater querying capacity, because all three machines in the cluster are actively queried. This is an improvement over the primary-standby mode, in which only the primary machine was queried.
When you upgrade the graph store to 11.5, it is placed in single-machine mode. See the upgrade section below for more information.
11.5 is the last release to support the tile cache data store
ArcGIS Data Store 11.5 is the last release to support the tile cache data store. That means the following:
- When you upgrade an ArcGIS Enterprise 11.4 or earlier deployment that includes a tile cache data store to 11.5, you will also upgrade the tile cache data store. Use the configuredatastore utility to complete the upgrade; do not use the Data Store configuration wizard. After you upgrade, existing hosted scene layers will still function.
- To publish hosted scene layers in an upgraded or new ArcGIS Enterprise 11.5 deployment, you must configure an object store.
- 11.5 is the last release that you can migrate existing hosted scene layer caches to the object store.
The administrator of the hosting server can run the MigrateSceneService utility that is installed with ArcGIS Server to move hosted scene layer caches to the object store.
ArcGIS Data Store upgrades
The changes described below affect upgrading ArcGIS Data Store.
Versions supported for direct upgrades
You can upgrade to ArcGIS Data Store 11.5 from ArcGIS Data Store 10.8 or later.
To upgrade from version 10.7.1 or earlier, first upgrade to an interim version, as shown below, and then upgrade that version to 11.5. Read the upgrade documentation for the interim version to perform the interim upgrade.
| Starting version | Interim version |
|---|---|
10.7 or 10.7.1 | 10.8.0 – 11.3 |
10.6.1 or earlier | 10.8.0 – 10.9.1 |
After you upgrade, configure an object store if you have not already included one in your ArcGIS Enterprise deployment. This allows members of the organization to publish hosted scene and 3D tiles layers. For more information, see the next two sections.
Graph store upgrades
If the existing graph store contains a single machine, there are no changes to the upgrade procedure.
However, if the graph store in your deployment contains two machines, the upgrade procedure has changed from prior releases.
- You must upgrade only one of the machines. When you do, the upgraded machine is placed in single instance mode, and the other machine is unregistered from the hosting server.
- If you still require high availability, upgrade one of the graph store machines and all other ArcGIS Data Store types in the deployment. Next, ensure that you have a default backup location configured for the graph store. and then you can use the configuredatastore utility to add two machines to the graph store to create a cluster.
Follow the instructions in Upgrade to ArcGIS Data Store 11.5, including the postupgrade tasks.
Also be aware that a graph stores deployed in cluster mode requires an TCP port 9830 to be available for communication between machines in the cluster. See Ports used by ArcGIS Data Store for a complete list of the ports required for each type of ArcGIS Data Store.
Tile cache data store upgrades
As mentioned above, you can upgrade the tile cache data store to 11.5 and existing hosted scene layers continue to function. However, because this is the last release that will support the tile cache data store, you must migrate hosted scene layer caches to the object store if you have hosted scene layers in your organization. After you migrate all caches and test the hosted scene layers, you can disable the tile cache data store. You won't be able to upgrade your deployment beyond 11.5 until you do this.
Port changes at 11.5
Starting with 11.5, the TCP ports 9820 and 9850 must be available on the ArcGIS Data Store relational data store machines for communication between machines. Additionally, port 9840 must be available on the relational data store machines to allow the hosting server to communicate with a system database on the relational data store machines.
The following ports are no longer required on the object store machines:
- TCP ports 9840, 9830, and 9820
- HTTP ports 9880, 29882, 29878 , 29876, and 29874
- HTTPS ports 29883, 29877, and 29875
See Ports used by ArcGIS Data Store for a complete list of the ports required for each type of ArcGIS Data Store.
The object store is part of a base ArcGIS Enterprise deployment
Before the members of the ArcGIS Enterprise organization can publish hosted scene layers or publish hosted 3D tiles layers, you must configure an object store. If the ArcGIS Enterprise deployment already contains an ArcGIS Data Store object store, it will be used to store caches for these layers when organization members publish them.
Evaluate the capacity of the existing machines in the ArcGIS Data Store object store. If organization members will publish large 3D tiles layers or scene layers, or a large number of these types of layers, consider adding disk space to the object store machine if it was deployed in single instance mode. If the object store was deployed in cluster mode, you can add disk space to the existing machines or add machines to the object store to account for additional data storage needs.
Changes and additions to ArcGIS Data Store utilities
The following are changes and additions to ArcGIS Data Store utilities:
- configuredatastore—As part of the changes to the graph store at this release, the --mode operation is expanded to allow you to change the mode of a graph store from single instance to cluster.
- describedatastore—As a result of the change in graph store modes, there are multiple changes to the properties reported for a graph store.
- Valid mode values reported for the graph store are now singleInstance or cluster.
- The Last failover property is no longer returned for the graph store because it is not relevant for data stores running in single instance or cluster mode.
- The Is cluster finalized property is added. It is set to true only when the third machine is configured for the graph store cluster; before that time, it is set to false.
- The Machines to be removed property reports the name of the graph store machine that is marked for deletion when you run the removemachine utility.
- removemachine—As noted above, when you run this utility to remove a failed machine from the graph store cluster, that machine is marked for removal. You must add a new machine to the graph store to bring it back to three machines before the marked machine is truly removed from the cluster.
