Dynamic Management of Service Instances

With the surge in the amount of GIS business data, the number of GIS services released through SuperMap iServer is also gradually increasing, which can reach thousands, tens of thousands, or even hundreds of thousands of magnitudes. For security GIS service management has stable performance, and SuperMap iServer provides GIS service instance dynamic management capability.

Service instance dynamic management provides the following capabilities:

1. 1. GIS service delayed initialization: When the iServer is started, the GIS service is not created by default and is in the "ready" state. When the service is accessed or used, it will be started immediately.
   2. Free Active destruction of GIS service instance: The scanned idle service (which has not been accessed or used for a period of time) will be actively destroyed and the occupied resources will be released. You can control the service lifetime by setting the service status, polling time, and idle service time.
   3. Maximum Online Service Instances Control: refers to the maximum number of simultaneous online service instances. This configuration can prevent resources from being overused. Availability of GIS system.

Application scenarios

1. • The number of published stock GIS services has reached thousands of orders of magnitude, and most of the GIS services are used less
   • frequently.
   • The GIS server resources are limited, and most of the GIS services are used infrequently, so it is necessary to reasonably control the use of resources to ensure the stability and availability
   • of the system

Usage

Dynamic management of service instances" is not enabled by default. You can enable this function at "global settings-dynamic management of service instances setting". Please refer to Dynamic Management of Service Instances Setting for specific configuration.

After enable the dynamic management of service instances, the service can be used normally. When the service is unavailable, it is because the maximum number of service instances is online at the same time. You can try again later or contact the administrator to adjust the maximum number of service instances.
