A cluster is a grouping of GIS server machines participating in an ArcGIS Server site. You can use ArcGIS Server Manager to edit and configure the machines participating in your clusters.
To edit a cluster in Manager, follow these steps:
- Open Manager and log in. If you need help with this step, see Logging in to Manager.
- Click Site > GIS Server > Clusters.
- In the
Clusters module, locate the cluster you want to configure and click Edit
. - Add or remove GIS servers from the cluster using the controls in the Edit Cluster Machines window.
If a GIS server you want to add to the cluster does not appear in the list, make sure it has been added to your site and is not currently participating in another cluster. For more information, see About adding a GIS server to a site.
If the cluster is currently hosting services and you remove all machines from the cluster, a warning displays indicating that the services will be stopped after applying your changes. If you require the services in the cluster to remain running, you'll need to add another machine to the cluster or edit the services to use another cluster before proceeding. For instructions on how to change the cluster hosting a service, see Editing service properties in Manager.
- Click Apply.
Note:
If you add a new GIS server to a cluster, the services configured to run in the cluster are automatically started on the new machine. Based on the number of services running in the cluster, it may take some time for your updates to be applied.
The edits to your cluster are applied and appear in the Clusters module.
