See the following topics in the ArcGIS Server help for information on configuring a highly available single-machine or multiple-machine server site: You should also configure your load balancer to regularly perform a health check of each server machine. To prevent downtime in the event of machine failure, configure these directories on a highly available file server. This pool of machines shares server directories and a configuration store. If you have multiple machines in your site, configure a load balancer to communicate with your pool of ArcGIS Server machines. How you implement a highly available server site depends on whether your web services reside on a single machine or are spread across multiple machines. You might also federate ArcGIS GeoAnalytics Server, ArcGIS GeoEvent Server, or ArcGIS Image Server sites with your portal.Īny or all of these additional sites, as well as your hosting server site, can be configured as highly available. You might choose to federate additional ArcGIS GIS Server sites with your portal to allow them to share authentication and to automatically register web services as items in your portal. This is an ArcGIS GIS Server you have dedicated to running your portal's hosted services, such as hosted feature, tile, and scene layers. The below sections describe how each component of ArcGIS Enterprise is deployed in a high-availability environment.ĪrcGIS Enterprise deployments contain a hosting server. Are you able to configure and maintain a third-party load balancer capable of performing failover?Ĭonfigure a highly available ArcGIS Server site.Do you have the hardware resources to duplicate each component of your deployment?.Is your organization able to provide the hardware necessary to support a highly available deployment?.Does your organization have the proper licensing from Esri to implement a highly available deployment?.

Will this ArcGIS Enterprise deployment be involved in mission-critical or business-critical operations?.Does your organization have a contractual mandate for high availability?.How is the service-level agreement enforced?.How many minutes or hours of downtime are permitted per year?.What percentage of uptime is required by the service-level agreement?.Does your organization have a mandated service-level agreement?.Organizations considering high availability should ask questions such as the following: It's important to determine whether high availability is required for your organization. When high availability should be usedĪ highly available ArcGIS Enterprise deployment is complex and requires time, effort, and cost to configure and maintain.
#ARCGIS FILE HANDLER HOW TO#
The topics in this section explain how to configure and maintain a highly available ArcGIS Enterprise deployment. Standby deployments in a highly available system, and a system administrator should always be available to take responsibility in the event of a failure. System updates should never be applied to both the primary and Organizational practices that ensure failover will always be The human component of a high-availability strategy consists of All mission-critical or business-critical elements of a deployment should be addressed when implementing high availability. Replicated systems, which rely on regular backups to minimize data Settings updates as the primary this distinguishes highly available systems from Standby deployment continually receives the same content and Primary to standby as soon as possible after machine failure. Involves maintaining at least two active copies of your deployment,Īnd implementing failover mechanisms to automatically switch from The infrastructure component of a high-availability strategy This strategy should comprise both infrastructure elements and employee practices neither can guarantee high availability alone. For these organizations, implementing a strategy to ensure high availability is crucial. Organizations often require a certain level of system uptime for their ArcGIS Enterprise deployments, such as 99 percent of the time or higher.
