多地图服务管理对象在ArcGIS Server中的设计与实现

Design and implementation of multiple map service management object based on ArcGIS Server

在基于ArcGIS Server的WebGIS应用中,服务器在生成海量地图服务时,由于每个地图服务都会占用大量服务器CPU资源,会导致服务器处于瘫痪状态。针对应用中遇到的瓶颈问题,提出建立基于ArcGIS Server的动态多地图服务管理对象的方案,将多地图服务管理对象置于GIS服务器端。当客户端发出新的地图请求时,进行多地图服务管理对象检验,根据设定的地图服务上限,向ArcGIS Server发出创建新的地图服务的请求或是发出删除某地图服务的请求,从而解决服务器经常处于瘫痪的问题。

In WebGIS application based on ARCGIS, when enormous map services generated at servers, each map services will occupy a large amount of server CPU resource, which will inevitably lead to server＇ s paralysis. To solve the problem, a muhiple map service management object is created. This object is set at GIS map server. When customer-issued a new map request, according to the upper limit, ArcGIS Server sent the request directly to establish a new map service, or to delete a map services.
